What generates blood pressure?
Blood pressure is the pressure of the blood pressing on the walls of arteries and veins. It is contracted by the left ventricle in the heart.
When the heart is contracted this corelates to which number in the blood pressure?
systolic and diastolic
What pressure does the action of the heart create in the blood vessels?
Blood pressure is the measure of the pressure created as the heart pumps blood through the blood vessels. This is one of the most important vital signs.
What is differenc between the blood pressure and heartbeat?
The heart beat is the beating of the heart. Blood pressure is the amount of pressure the heart beat causes the blood to push against the blood vessels.
What is the difference from systolic blood pressure and diastolic blood pressure?
Systolic (the higher number) is a reading of the pressure in your blood vessels when your heart is beating at its maximum strength. Diastolic (the lower number) tells you what the pressure is in your blood vessels when your heart is at rest.
What moves blood through the blood vessels?
Your heart. Your heart pumps and that moves the blood.
What is systolic pressure measured?
The pressure inside the blood vessels at the end of the contraction of the heart. Diastolic pressure is the pressure between beats when the heart is relaxed. Blood pressures are systolic/diastolic; 120/80.
Can meths use enlarge the heart?
increased heart rate & blood pressure, damaged blood vessels in the brain that can cause an irregular heartbeat that can cause cardiovascular collapse or death, permanent damage to blood vessels of the heart, & heart attack.
What is blood pressure used to evaluate?
Your systole and diastole (or systolic and diastolic pressure). Systolic pressure is the pressure your blood exerts on blood vessels when your heart pumps out blood while diastolic pressure is the pressure your blood exerts on blood vessels when your heart is at rest(in between pumps). Blood pressure is stated as systolic pressure/diastolic pressure. The normal BP is 120/80 mmHg.
What is the effect of hypovolemic shock on the blood vessels and the heart?
Blood vessels constrict to increase venous return and maintain pressure. Heart rate increases to compensate for loss of blood pressure and to maintain cardiac output.
Why is high blood pressure angerous?
High blood pressure can damage your heart, eyes, kidneys, blood vessels and brain
How does your pulse and blood pressure work?
Your "pulse" is how fast your heart is beating, and is measured in how many beats in a minute. This is controlled by several things. One is how healthy your heart is (if you have a strong heart, i.e. from exercising, your heart does not have to beat as often for the same effect and therefore your pulse will be lower). If you are exercising, your pulse or heart rate will increase to meet the increasing oxygen demands of your muscles. Also, if you are afraid, stressed out, or angry, your sympathetic nervous system stimulates the "flight or fight" response which increases your heart rate for the same reason. Your Blood pressure, however, is how much pressure is actually being exerted on the insides of your blood vessels when your heart beats. This is affected by three things: the size of your blood vessels, the strength of your heart, and the amount of fluid or blood in your bloodstream. The flight or fight response can affect these things by causing your heart to beat harder, therefore exerting more pressure, and by causing your blood vessels to constrict, or narrow. Both of these things raise your blood pressure. Again, exercise also causes your heart to beat harder and raises your blood pressure. Nicotine causes your blood vessels to constrict and this increases blood pressure. If you are dehydrated or bleeding severely, your blood pressure goes down because there is less fluid in your blood stream. Your body will compensate for this by increasing your pulse rate and constricting your blood vessels. The numbers you see in a blood pressure represent your systolic Blood Pressure (the first and usually higher number) and your diastolic Blood Pressure. The systolic blood pressure is the pressure exerted on your blood vessels when your heart pumps. This is why this pressure is higher. The diastolic Blood Pressure is the pressure in your blood vessels in between heart beats. Review: Related Links for more info.
