Systolic Pressure (the other is Diastolic) is the squeezing of the ventricles as they push blood out of the heart and along the arteries to either the body or the lungs.

Diastolic Pressure is when the heart is at its most relaxed after the Systolic squeezing.

ie a Blood Pressure reading of 120/80mm Hg (which is the ideal) is 120mm HG Systolic Pressure - when there is the most force pushing the blood - over 80mm HG - when there is the least force behind the blood flow.

systolic reading denotes the force of contraction of heart and diastolic reading represents relaxation of heart

145/85 is an elevated blood pressure reading. A chronic reading at this level indicates high blood pressure.

Systolic pressure and Diastolic pressure

Many online health and doctor sites such as WebMD, MayoClinic or HealthCentral provide information also for healthy blood pressure. Typically a blood pressure that is considered normal is systolic between 120 and 140 and diastolic between 80 and 90. Low diastolic pressure is called hypotension in medical terms.

Blood pressure is usually expressed in terms of the systolic (maximum) pressure over diastolic (minimum) pressure and is measured in millimeters of mercury (mm Hg). The top number is the largest and that happens when the heart is contracting. The lower number occurs when the heart is relaxed before it beats again.

Blood pressure is usually expressed in terms of the systolic (maximum) pressure over diastolic (minimum) pressure and is measured in millimeters of mercury (mm Hg).

In medical terms, an agent usually refers to a medication. For instance, an antihypertensive agent reduces blood pressure.

Blood pressure is one of the vital signs upon which doctors and other health professionals rely to understand the health of a patient. The phrase refers to the amount of pressure that blood exerts against the walls of the blood-carrying vessels when the heart pumps. Since there is always some pressure as long as there is blood in the veins and arteries, this reading is given in two parts. Systolic blood pressure is the maximum pressure and diastolic is the minimum amount of pressure.Blood pressure is rated according to its ability to raise a millimeter of mercury. This is written in terms of mm/Hg. Thus, a systolic reading of 100 and a diastolic reading of 70 would read as 100 mm/Hg over 70 mm/Hg. However, it is much more common to simply use the numbers when the context of blood pressure is already given. In that case, the blood pressure reading would simply be given as 100/70. Desirable blood pressure levels are anywhere between 90/60 and 120/80.High Blood PressureHigh blood pressure readings are any reading over 140/90. This is a condition known as hypertension. This can increase the likelihood of heart disease in a person's lifetime. Causes for this condition vary but one primary cause is too much sodium in the bloodstream. Many other substances have a similar effect, such as alcohol and caffeine. This tendency can also be genetically inherited. Treatments are available and medication for hypertension is one of the most commonly prescribed drugs in the United States.Low Blood PressureLow blood pressure is known as hypotension. It is a less common affliction than hypertension but carries serious consequences as well. The lack of sufficient pressure can cause blood flow to the brain to become insufficient. This results in lightheadedness and fainting. This condition is caused by a variety of things, among them hormonal abnormalities, sepsis and eating disorders such as anorexia and bulimia.

Blood pressure is usually expressed in terms of millimeters of mercury (mmHg).

A drop in blood flow, or blood pressure, is known as hypotension. Other terms can be used to describe the specific lack of blood flow, such as "ischemia," and "hypoxia."

Oxygen moves into the blood because the partial pressure of oxygen is higher in air and lower in blood. Carbon dioxide moves out of the blood because the particle pressure of carbon dioxide is higher in blood and lower in air.

no its high pressure to low pressure cos when the heart pumps the blood, the pressure is most and thicker veins have to be present to accomodate such a high pressure. Gradually the pressure decreases as if put it in terms of physics, most kinetic energy is converted to other forms of energy thus slowing down and pressure is lesser. Hope that my answer is correct.

How is blood pressure measured?To take a blood pressure reading, you need to be relaxed and comfortably seated, with your arm well supported. Alternatively, you can lie on an examination couch.* A cuff that inflates is wrapped around your upper arm and kept in place with Velcro. A tube leads out of the cuff to a rubber bulb.* Another tube leads from the cuff to a reservoir of mercury at the bottom of a vertical glass column. Whatever pressure is in the cuff is shown on the mercury column. The mercury is held within a sealed system - only air travels in the rubber tubing and the cuff.* Air is then blown into the cuff and increasing pressure and tightening is felt on the upper arm.* The doctor puts a stethoscope to your arm and listens to the pulse while the air is slowly let out again.* The systolic pressure is measured when the doctor first hears the pulse.* This sound will slowly become more distant and finally disappear.* The diastolic pressure is measured from the moment the doctor is unable to hear the sound of the pulse.* The blood pressure is measured in terms of millimetres of mercury (mmHg).Blood pressure can be measured in other ways, such as using an automatic blood pressure gauge that can also be used at home.

In terms of an incoming emergency room patient, vital statistics include: pulse and blood pressure.

Blood pressure (BP) is the pressure exerted by circulating blood upon the walls of blood vessels, and is one of the principal vital signs.When used without further specification, "blood pressure" usually refers to the arterial pressure of the systemic circulation.During each heartbeat, blood pressure varies between a maximum and a minimum pressure.The blood pressure in the circulation is principally due to the pumping action of the heart.Differences in mean blood pressure are responsible for blood flow from one location to another in the circulation. The rate of mean blood flow depends on the resistance to flow presented by the blood vessels.Gravity affects blood pressure via hydrostatic forces (e.g., during standing), and valves in veins, breathing, and pumping from contraction of skeletal muscles also influence blood pressure in veins.A person's blood pressure is usually expressed in terms of the maximum pressure over the minimum pressure and is measured in millimeters of mercury (mm-Hg), for example 120/80.Various factors, such as age and sex, influence a person's average blood pressure and variations in it. In children, the normal ranges are lower than for adults and depend on height. As adults age, the maximum pressure tends to rise and the minimum pressure tends to fall.In the elderly, blood pressure tends to be above the normal adult range, largely because of reduced flexibility of the arteries. Also, an individual's blood pressure varies with exercise, emotional reactions, sleep, digestion, and time of day.

The National Heart, Lung, and Blood Institute (NHLBI) says about 1 in 3 adults in the U.S. may have high blood pressure (HBP) or hypertension. Many people called HBP the "Silent Killer" because it does not have any known symptoms. When left unchecked, the disease causes damage to the heart, kidneys, blood vessels, and other parts of the body.Blood pressure measures the force of the heartbeat as it moves blood, which contains oxygen, to all parts of the body. As blood flows through arteries and veins, it stretches the tissue that makes, up the walls. We describe this "force" in numerical terms, such as "one-twenty over eighty," "120/80," which measures blood pressure in two ways:As the heart beats and pumps blood through the vessels or systolic blood pressure--top number.The heart when it's in the rest state or diastolic blood pressure--bottom number.According to NHLBI, blood pressure readings of less than 120/80 milliliters of mercury (mmHg) -- for both numbers-- represent a normal reading.Remember, you will not become aware of HBP with signs or symptoms.In rare cases, an individual with HBP may experience a headache, dizziness or nosebleeds. By then, the high blood pressure may have reached a critical stage or become "life-threatening." NHLBI defines high blood pressure as blood pressure readings over 140/90 mmHg.HBP readings between 120139 or 8089, warn of pre-hypertension. Readings of 130/80 mmHg, or higher for individuals who have diabetes or chronic kidney disease, indicate high blood pressure. HBP numbers vary for children and teenagers.Having the proper blood pressure helps you form a solid foundation for maintaining good health. Make it part of your health check routine to "know your blood pressure numbers," even when you feel good and healthy. Take multiple blood pressure readings over a three-day period and calculate your average blood pressure.Persons with pre-hypertension or HBP must work with their health care practitioners and take the steps required to get the disease under control. Individuals with normal blood pressure should work with their health care team to maintain normal blood pressure and healthy lifestyle.

agreement, talk to terms, understanding

When one describes Bld. Pressure in layman's terms, it can be said that the top # 167= the amt. of pressure against the bld. vessels at the moment; and I believe the lower # represents the consistent pressure. 67 is lower than the average of 80. So this B.P. probably represents an anxious individual whose anxiety increased the B.P. at the time (most likely increased heart rate>100BPM=beats per min.) 60-100BPM=normal. The reading of 67 is indicative of individual with low to average B.P. if this diastolic reading is consistent in findings. Systolic=upper # Diastolic=lower reading. Decreasing one's ANXIETY level will most likely lower this systolic reading of 167. Make sense? Stay cool...RELAX; and your B.P. will be less likely to be HIGH...R.N./Mass.

What are the Causes of High Blood Pressure?Understanding what causes high blood pressure will help you to control it.As a first step, let's talk about your heart.Your heart is an organ that is mostly muscle tissue. It is a pump. In very simple terms its job is to receive incoming blood from the body that is low in oxygen and pump it to the lungs.As it passes through the lungs the blood gets rid of carbon dioxide and picks up oxygen. Then the blood goes back to the heart and the heart pumps the oxygen rich blood out to the entire body.Blood flows through arteries going out from the heart to various parts of the body, and through veins on the way back to the heart.The heart pumps blood by the rhythmic contraction of the four chambers in the heart. It is the strong contractions of the lower two chambers (called ventricles) that pumps the blood out of and away from the heart to the various parts of the body.There is a great deal of pressure created by the contraction of the ventricles. and it is this pressure that pushes the blood through the miles of arteries within the body.It is the pressure, the force of the blood pushing against the inside walls of your arteries, that is being discussed when we talk about blood "pressure."What do the numbers mean?You've probably heard the sound of a heart beating at some time. It sounds sort of like: lub-DUB, lub-DUB, lub-DUB, lub-DUB.The "lub" is the sound of the auricles beating and pumping the blood into the bigger, more powerful chambers, the ventricles. The "DUB" is the sound of the ventricles beating, and pumping the blood away from the heart (see the above illustration).When the powerful ventricles contract (the "DUB"), that is the moment of greatest pressure called the "systolic pressure."Between one "lub-DUB" and the next "lub-DUB" is a moment when the heart is not beating at all, that is the moment of lowest pressure called the "diastolic pressure."When doctors or nurses measure your blood pressure, they usually give it to you as two numbers, the "systolic" over the "diastolic" or the high over the low measurements.These numbers fall into certain ranges:What controls blood pressure?Blood pressure is controlled by tiny muscles that line the inside of your blood vessels.These muscles allow your arteries to operate like soft rubber tubes, that expand with each beat of your heart.When these muscles throughout the vascular system [the arteries and veins that carry blood] expand, blood pressure drops.When these muscles throughout the vascular system tense up, blood pressure rises.When these muscles get tense, the arteries become narrower, more rigid, less flexible, and the heart has to beat harder to keep the blood flowing through these narrower tubes.If the muscles that line your arteries are tense all the time, the blood pressure will remain high. This is called hypertension!Continuous high blood pressure puts extra strain, wear and tear on your heart and arteries, that can eventually lead to heart attacks and strokes.What Causes High Blood Pressure?What is it that makes the muscles that line your blood vessels tense all the time? What are the things that can actually drive your blood pressure up?* Poor diet* Nutritional deficiencies* Being overweight* Alcohol and caffeine in excess* Emotional and physical stress* Being diabeticEach of the above can cause the loss of vital minerals from the body. These minerals are essential to the natural and effective control of blood pressure."Magnesium is essential for cells to maintain proper balances of other minerals such as potassium, sodium, and calcium.""When cells are deficient in magnesium, this balance is disrupted, and cells lose potassium and are flooded with calcium and sodium.""In the smooth muscle cells of the blood vessels, this sets the stage for constriction and elevation of blood pressure."excerpted from The Magnesium Solutionby Jay S. Cohen, M.D.Not having enough magnesium is one of the main causes of high blood pressure."As many as half of us in the United States are magnesium deficient.""Our soils are becoming depleted of magnesium, which eliminates the natural opportunity to receive magnesium from fruits, vegetables, and water."excerpted from The Sinatra Solutionby Stephen T. Sinatra, M.D.

Thrombus in medical terms means blood clot.

Literary terms in certain contexts.

Heat causes the body to adapt in many ways as we require to maintain a steady internal temerature. An increase in heat causes us to sweat more, so that when the water evaporates it takes the heat with it to cool us down, maintaining Homeostasis. The water in the sweat has to come from somewhere and that somewhere is usually the blood. So if heat increases the water content of the blood plasma decreases, this means the pressure of the blood decreases. The term "thin" in relation to blood used to mean a low blood pressure but this term is archaic nowadays. Usually thickness in terms of a fluids is relates to Viscosity (higher the viscosity less runny). If the water is being removed from the blood then the concentration of everything in it is increasing (the Osmolarity is increasing), meaning its viscocity is increasing. So in these terms it is true to say that heat thickens the blood. In other words the terms thick and thin in relation to blood are so ambiguous they should not be used, blood pressure or osmolarity should be used depending on what is trying to be said.

Blood pressure ranges are incredibly important to understand for people with or without blood pressure issues. In most simplistic terms, blood pressure is the force exerted on the walls of bodily arteries by circulating blood. The most favorable blood pressure levels are less than 120/80, or one hundred twenty over eighty. If blood pressure becomes higher than this number, than a person may be in the mild, moderate or severe high blood pressure ranges. The higher blood pressure ranges need to be treated with medicines or they will be severely detrimental to a person's health. While high blood pressures are not to be taken lightly, it is important to understand that at certain times, a person's blood pressure can reach higher numbers without too much concern involved. For instance, blood pressures will be naturally higher when a person is physically exerting themselves. However, if a person's blood pressure is high while at rest, it means that their heart is overworked and their artery walls have unneeded extra stress being exerted upon them. Of course it is also important to remember that low blood pressure is just as much of a problem as high blood pressure, so it is wise to know blood pressure guidelines. Below normal blood pressure numbers will hypotension, or low blood pressure. Normal blood pressure ranges from 90-119/60-79, or ninety to one hundred nineteen over sixty to seventy-nine. Therefore, low blood pressure ranges will be below these normal blood pressure ranges. Pre-hypertension ranges, or mild blood pressure ranges, will be anywhere from 120-139/80-89, or one hundred twenty to one hundred thirty-nine over eighty to eighty-nine. Stage one hypertension, or moderate blood pressure ranges, will be from 140-159/90-99, or one hundred forty to one hundred fifty-nine over ninety to ninety-nine. Stage two hypertension levels, or severe blood pressure levels, will range anywhere 160/100, or one hundred sixty over one hundred, or higher. It is critically important to know these levels, especially if you have a personal or family medical history of blood pressure problems. Even if you have never had blood pressure problems personally, it is important to know these numbers for future reference. Blood pressure can be measured with certain medical devices that can be purchased in many stores, so be sure to invest in an instrument to measure your own blood pressure in the future if you have not done so already.

In terms of physics pressure means the force per unit area. When an object is placed on a surface such as a desk the pressure is the weight of the object against the surface.
