Heart

No. The medical term for heart attack is myocardial infarction, or the death of heart myocardium (basically the heart muscle). Coronary Heart Disease (CAD) is a disease where plaques of cholesterol are deposited in the heart's coronary arteries (which feed the heart blood during diastole). Ruptures of these plaques can cause clots in may however result or cause myocardial infarctions, due to a sudden yet complete blockage of a coronary artery.

Typically, fluttering of the heart is called "palpitations."

It is called the Mammalian Diving Reflex. It is because the pressure increases underwater. Many other things happen as well. Check out these websites Wikipedia and Buzzfeed

You lose your chair because you are standing up.

Actually, the answer to the riddle is: "You lose your lap."

The coronary stent is a tube placed in the coronary arteries to keep them open and is a treatment for coronary heart disease. It is an intervention to prevent heart attacks and more damage to the heart.

Hydrostatic pressure is generated by the systole (contraction of the ventricles).

Because pressure is built up in the left ventricle of the heart before it is forced out through the aorta in order for blood to be forced around to the body efficiently to the cells where it is needed. Without this high pressure, blood would not be efficiently ejected to the body and it can pool in the ventricles, which can cause problems.

This high pressure in the ventricle is also required in order for blood to travel around the body. This is because blood moves from an area of high pressure to low pressure to travel. This same principle is used for cells to gain oxygen and other necessities. For example, oxygen will diffuse from the capillaries (smallest blood vessels) which has a high concentration of oxygen into cells, which have a low concentration of oxygen.

Hope this helps ! :)

Move on. There's plenty of fish in the sea. If they hurt you they obviously don't care enough about you for you to waste your time on them.

people might brake your heart but if they do they dont really care about you do they so move on with your life dont let one person get in the way of you living your life Unfortunately it is difficult to deal with a situation like this. Sometimes people state that we should "move on" like in the answer given above. The Bible however teaches another perspective on heartbreak. The Bible teaches to love those that hate us. To forgive even those who hurt us. It teaches to give unconditional love, and to not be angry. It teaches that if a man has offended another he should go and be reconciled before the other person, if it is possible. But it does say "if it is possible"... and sometimes it's not possible, but the only way to know if it is possible is to try.

systemic circulation
This is a fairly basic explanation. You would start off with the oxygenated blood leaving the left ventricle of the heart, through the aorta, then the blood would move into atrioles, and into the organs. There it would move into cappillaries and the oxygen in the blood would diffuse through the walls of the cappillaries and carbon dioxde from the organ its in would diffuse through the capillary wall and into the blood, where it would leave the organ through venules. They would transport the blood into veins, which would bring the de-oxygenated blood back around into the heart through the vena cava, inferior or superior.

there are 4 chambers of the heart. the left and right atrium and the left and right ventricle. the left atrium is where the blood enters the heart and leaves through the left ventricle and the opposite for the only side only to the lungs instead of the body

Your heart works with the circulatory (heart, blood, vessels) and respiratory system (nose, trachea, lungs). The hearts pumping action helps to circulate blood through the body. The heart must be supplied with rich fresh oxygen and used blood must be returned to the lungs for reoxygenation.. (This is an example on how the heart works with the lungs.)

Cardiac muscle forms the muscular wall of the heart. Cardiac muscle is involuntary muscle.

The larger the animal, the slower the heartbeat.

A rat's heartbeat is like a bee buzz...

Any insufficiency in the delivery of blood to the body is fatal. Chronic insufficiency interferes with oxygen exchange in the lung, the function of the kidneys and liver function. Your heart is the main reason you are alive, if something is wrong with your heart there is a strong chance you will die. Your heart is responsible for not only for a transport system but it is used to fight disease, but if the heart is the diseased, your heart is less likely to save itself. It is important to keep your heart healthy by regular exercise and a healthy/balanced diet, and to avoid bad habits like smoking and drinking and junk food.

There are different diseases of heart and they impact the heart slightly differently. The one that gets so much attention is coronary artery disease. This is where the blood flow to the heart is diminished due to blockages in the arteries that feed the heart blood and oxygen. This makes your heart work harder and may stop functioning normally until it can regain proper blood supply. Heart By-pass surgery allows the arteries to go around the blockage and allows blood to flow freely the the cardiac tissue.

after the first heart sound is made ventricles starts emptying.

Oxygenated blood enters the heart in the pulmonary vein. It passes through the left ventricle, before exiting in the aorta.

Your heart pumps about five liters of blood per minute. This is also called as cardiac out put. In severe exercise the cardiac out put can increase up to twenty five liters per minute.

Resting heart pumps about five liters of blood per minute. In severe exercise the heart can pump up to twenty five liters of blood per minute.

There are more than one reason, sometimes when a woman is pregnant, or if someone is anemic, the heart will have a "conpensatory systolic heart murmur" to just add an extra beat of the heart to give the body a little extra oxygenated blood every few beats. Also sometimes when their is a mitral valve problem, the heart will have a murmur.Often after the anemiais taken care of or the baby is born the murmur will just disappear.

brain cells are activated by brain genes and heart cells are activated by heart genes. that's how they function, by their genes

The heart has 4 quadrants. The Right and Left atrium (on the top) and the Right and Left ventricles (on the bottom)

Deoxygenated blood enters the right atrium via the superior and inferior Venea Cava. From there it goes through the tricuspid valve into the right ventricle and then flows threw the pulmonic valve into the pulmonary artery (the only artery in the body to carry deoxygenated blood) and goes to the lungs to become oxygenated. The now oxygenated blood leaves the lungs via the Pulmonary vein (the only vein in the body to carry oxygenated blood) and then enters the left atrium. From the left atrium the blood flows threw the mitral valve into the left ventricle (the biggest and strongest portion of the heart) where it is then pumped out of the aortic valve to the body!

Heart attacks do hurt. It is when the tube that leads to your heart gets clogged. Then, your body cannot pump blood, so all of it rushes to your head and you see stars. Then you pass out.

I know this personally because I have had 2 heart attacks before. Be sure to check your cholesterol level AT LEAST every 2 years. Don't eat to many hot dogs, shrimp, hamburgers or steak because they all ( and more) cause plaque build up and plaque is how the tube is clogged. I hope this helps and stay healthy!!

No, semilunar valves control the flow of blood out of the heart.
