Heart

Through the vena cava. Blood enters the heart at the right atrium when from the systemic circulation. It Gets here through the superior and inferior vena cava and the coronary sinus. From the pulmonary circulation it enters the left atrium from the pulmonary vein.

One could be like my father's to where the heart cannot produce enough blood for the circulation of the body. A way to get this disease is smoking and/or drinking or even if it runs in your family you could get it. If you have it a good way to make it stronger is to eat healthier, exercise, and get rest do not strain yourself; when you take your pain medication lay down, take it easy for an hour or two.

Cardiac arrest, arrhythmia, ventricular aneurysm, and death

the pulmonary system.

animal tissue, usually a pig's aortic valve. Another is mechanical and is made of metal and plastic. The third, includes human valves that have been removed from an organ donor

The endocardium

The myocardium is not the innermost layer of the heart, the endocardium is.

The cardiovascular system brings blood to the body. You have more than 50,000 miles of blood vessels in your body.

Ventricular fibrillation is the term for rapid irregular contractions of the ventricles. Because the contractions are unsynchronized and random, the ventricles do not pump effectively. The patient may have no palpable pulse, and the condition can be fatal.

A myocardial infarction, commonly referred to as a heart attack, occurs when the blood supply to the heart is cut off. This is usually the result of plaques in the arteries, that form blood clots if they rupture.

The heart sends deoxygenated blood to the lungs, via the pulmonary arteries - thus this system is called the pulmonary circuit

De-oxygenated blood flows from right ventricle of heart to lungs through two pulmonary arteries for oxygenation. After oxygenation the blood now travels through the pulmonary veins to left auricle of heart. Two pulmonary veins from each lung reach the heart making a total of four pulmonary veins. This circulation of blood to and from lungs is called pulmonary circulation. The pulmonary vein is thus the only vein which carries oxygenated blood and pulmonary artery in the same way the only artery to carry deoxygenated blood.

It is a result of thousands of years of evolution. But you also have to look at their functions. The left ventricle is pumping deoxygenated blood through the pulmonary artery to the lungs and back to the left part of the heart (including the left ventricle) which then pumps the oxygenrich blood out in the body. I guess you can imagine that pumping the blood in the body requires more work than pumping the blood to the lungs and back.

I suggest you read more about the circulatory system and the heart if you have an exam or something that you have to prepare to.

If you're asking "Are abnormal heart sounds caused by valvular disease?," the answer is "sometimes." If you're asking "What are the abnormal heart sounds caused by valvular disease?," the answer is "it varies with the type and degree of disease." One of the most common abnormal heart sounds caused by valvular disease is a whooshing or swishing sound instead of the sharp thumping beat of a valve that's functioning properly.

The Mitral valve.

There are many vessels serving as conduits between the lungs and the heart. This is because the heart and the lungs need enough oxygenated blood at all times.

The left atrioventricular valve stops the back-flow of blood by only being opened if a large force or pressure is behind it (in the left atrium) and is closed if a large force or pressure is in front of it (in the left ventricle).

septum

There are plenty of them available, and they can be built to fit the patient, unlike waiting for a donated organ. Also, the patient is more likely to know what day they're having surgery on with an artificial heart, rather than waiting for a call saying there is an organ available.

They're parts of the four cardiac chambers.Deoxygenated Blood from the inferior and superior vena cava goes to the the heart's right atrium and through the tricuspid valve in to the right ventricle (which is then pumped to the lungs to rid of CO2 and get O2diffused into the blood). They are both parts of the heart, and They come in pairs inside the heart. They both contain valves that prevent the back flow of blood. A difference is that the atria has thin walls and the ventricle has thick walls. The atria are receiving chambers and the ventricles are discharging chambers - they pump the blood.The septum in-between the atria has the foramen ovale, a closed opening that used to be present in a fetal heart.

Blood vessels are the tubes that carry blood. The three types of blood vessels are arteries, capillaries, and veins.

The ericardium is the fluid filled sac that surrounds the heart and keeps it contained inside the chest.

You have pulmonary aorta that arises from the right ventricle. It splits into right and left branches. The branches most probably continue to divide with the bronchi. Ultimately you have the network of the capillaries to cover the alveoli.
