Heart

with excercise. When your heart gets pumping hard from physical activity, it gets stronger because it's a muscle, and muscles get stronger with use (not just picking up your coffee kind of thing, but like really using them like you do when you excercise).

Your state of mind affects your pulse rate.

There are many contributing factors such as Fear, laughing, breathing etc.

· Loud Noises

· Exercise

· Caffeine

· Television

. scary movies ...........

And loud tempo music.........

The heart itself is a muscle, however the heart all is made up of different muscles. The muscle knows as the MYOCARDIUM makes up the largest portion of the Heart Wall. The myocardium is made up of the cardiac muscle tissue, which is responsible for the pumping action.

Smoking damages the lungs, so that the blood does not get all the oxygen it needs. This deprives the body from oxygen, and causes the heart to overwork. An overworked heart is not a happy heart.

The left atrium receives oxygenated blood from the pulmonary vein.

To prevent the back flow of blood into the left and right atrium when the ventricles contract

The smallest heart chamber is the left atrium. The right atrium is slightly larger than the left.

chronic heart failure is demonstrated by a cardiac catheterization or nuclear medicine study. During cardiac catheterization, the patient's cardiac function will be measured by cardiac output, ejection fraction and cardiovascular pressures.

Heart disease is becoming more and more common due to the fact the growing number of people eating unhealthy foods regularly such as processed foods like fast food and ready meals. These foods contain lots of saturated fats and salts which can cause heart disease and cardiovascular disease, which do kill. Many more heart disease charities are being set up for the increasing number of deaths due to heart disease and deaths due to this disease are becoming more common as is the disease itself.

Yes, it does. So that you can get oxygenated blood throughout your body, the right side pumps de-oxygenated blood not to the whole body, but just into to lungs to pick up the oxygen it needs, to return to the heart and be pumped to the rest of the body.

Some of the warning signs of congenital heart failure are fluid filling up in the lungs, less of a appetite and becoming out of breath easily and not falling to sleep unless sitting fully upright.

the bicuspid/mitral valve is located in between of the two.

Some holes are harmless and may be left as they are. Others may cause severe harm leading to death and must be corrected by surgery so that the child may live.

Four chambers, left ventricle, left atrium. The right atrium and ventricle ( send blood to the lungs ). There are valves that stop the blood from backing up into the atria and the veins. And there are coronary arteries. There's a few more miscellaneous parts, but that covers the major stuff.

A normal heart rate at rest is 60-100 BPM For more information contact me: Elliottcollins@hotmail.co.ukHow_heart_worksIM 17 TOO!!!!!!!!!

You should not get any tattoo work done soon after a major surgery, or after experiencing anything that has caused trauma to your body. Your body needs time to recuperate, and does not need to have to focus on healing a tattoo (which is essentially a wound) in addition to recovering from surgery or any kind of injury.

The longer you wait to get a tattoo after your valve replacement, the better.

the sounds of the heart "LUBB-DUPP" are produced due to the sharp closure of the valves of the heart. the first sound is produced when the auricular-ventricular valve(bicuspid and tricuspid valve)closes. the second one is produced when the semilunar valves(pulmonary and aortic valves) close.

The veins have small valves that allow the flow in only one direction, so that muscle movement in the legs act to push the blood towards the heart. This is why it is so important for people to walk or shift their weight when standing for a prolonged period.

It comes from the left ventricle out through the aorta.

yes, your heart stops beating only when your dead.

The blood enters throught the heart throught the right and left atria. As the heart contracts, blood flows into the ventricles and then out from the ventricles.

A frog is an amphibian. An amphibian heart is characterized by three chambers. Two auricles and one ventricle constitute an amphibian heart. Hence, an amphibian heart appears like a pyramidal structure turned upside down.

If you are thinking of the organ, the heart, its main function is to pump blood throughout the body. Blood circulation is vital because this is how most of the organs of your body are able to get nutrients and oxygen as well as get rid of waste products.

If there was no heart, the blood in your body would settle down in the lower parts because there would be nothing to work against gravity.

So the heart is the pump for the blood. It pushes the blood to, and through the lungs so that new oxygen can enter the bloodstream and carbon dioxide (and other gases) can leave the blood. The heart also pumps the blood through the various organs that perform specialized functions, such as the liver and kidneys, which work to remove waste products from the blood. The heart also pushes the blood around your whole body, even forcing the blood into the capillaries that surround most living tissue in your body.

This is why people with heart problems often have swelling in their hands and especially their feet. It takes a lot of force to move the blood throughout the vessels in your toes. When you heart isn't working with enough force blood can pool, or gather in the tissues that are the farthest from the heart.

People have four chambers in their heart, and each pumps blood at a different stage. This is why it is so dangerous when the heart's rhythm is interrupted. It's as if there were four pumps working together when one starts pumping at a different rate or at a different force than the other pumps.

Your heart doesn't have its own "brain" to decide when to pump, that information comes from your head. The human brain sends special electrical signals to your heart. These small electrical pulses cause the various muscles that make up your heart beat at the right times.

Many dangerous problems with your heart happen when the muscles or something in the links between the brain and your heart get confused. The special first aid treatment with the big paddles and the electrical shock is designed to get the heart muscles back into sync with one another. In one sense it is like hitting a reset button. This special electric shock is designed to reset the timing of your heart's beats, which often fixes at least some of the problems that cause a heart to stop working correctly.

If you are asking about the "spiritual heart" (hence the posting in this section), the role of the "heart" changes from society to society. Some ancient cultures believed that the head was where your "soul" lived. Others believed it was the liver, or other organs. The view that "won the contest" throughout most of the world was that the human heart was the place where human life centered.
