Heart

There are two other options. The efficiency of the heart and other body systems should increase with the age. You can imagine the consequences of that. The efficiency of the 500 years old people will be more than 400 years old. The other option is that the efficiency of the people should remain same with the advancing age. Then why should he die all of sudden with out the reason? The fact is that the nature is not interested in you once you pass the reproductive age group. The fact is that all the animals take care of the young ones. No animal species take care of the elderly animals. Be thankful too the society and family for taking care of the elderly people. So it is too natural to lose the efficiency of the heart as the age advances. This process is called as ageing.

Dr. Daniel hale Williams first performed surgery on James Cornish's pericardium in 1893.The pericardium is the sack that that surrounds the heart.Cornish was the victim of a knife attack.He did not perform a heart transplant.

during diastolic phase the chambers of heart get filled with blood

systolic phase and diastolic phase are the phases oh heartbeat

and diastolic phase is also known as resting phase.

left ventricle

The heart of mammals (and birds) is completely divided into two sides, left and right. Blood cannot pass directly from one side to the other, but has to leave the heart first. For example, blood from the right side goes first to the lungs before returning to the left side of the heart. Blood from the left side goes round the body before returning to the right side. Blood passing through the right side of the heart is deoxygenated ie it has had oxygen removed as it circulated through the body. Blood passing through the left side of the heart is oxygenated, as it has collected oxygen in the lungs before returning to the heart. So, each side of the heart works as a separate pump, one side pumping deoxygenated blood and the other pumping oxygenated blood. Because the two pumps are physically connected to form one organ, the heart is called a double pump. In the embryo, the heart begins as two separate tubes lying side by side which then fuse together. See: http://www.bbc.co.uk/science/humanbody/body/factfiles/heart/heart.shtml

The pericardium surrounds the heart like a protective sac. It contains fluid that decreases friction.

The fat eventually builds-up in the coranary vessels and this means that blood flow will be restricted. This mean that the heart is being deprived of blood and oxygen (which is essential for the heart to work properly) and a heart attack (at that stage) is going to happen.

The epicardium is the outer layer of the heart.
Epicardium

The left atrium of the heart receives oxygented blood from the pulmonary veins returning oxygenated blood to the heart.

You are talking about the pulmonary circulation. The blood (low in oxygen) is pumped by the right ventricle to the lungs by way of the pulmonary arteries. It comes back after it drops off carbon dioxide and picks up oxygen at the lungs. It finishes the circle when it comes back to the heart by way of the pulmonary veins into the left side of the heart.

You mean, what is the function of the auricle?

Auricles are ear-like flaps of tissue projecting from the atrial chambers. They function to help increase the capacity of the atria, which in turn, increases the amount of blood that the atria can hold.

yes certainly panic attacks are bad, because when there is an attack the heart beat rate will increase and sudden adrenaline rush in the body , They might feel very thirsty and sweaty. Immediate treatment would be to calm them down and start taking deep breath and drink water. more tips available at http://trainyourmind.blogspot.com

interatrial (between the atria)

interventricular (between the ventricles)

atrio-ventricular (between the atria and the ventricles)

So, each chamber is separated by a septum

The heart and lungs work together to deliver oxygen to and remove carbon dioxide from the body's tissues. The brain uses this oxygen to function.

During systole, both atrioventricular valves (tricuspid and mitral) are closed. The aortic valve is open. During diastole, both atrioventricular valves are open, and the aortic valve is closed.

No, dead muscle is dead muscle - however the genius of the human body is that it can adapt. If there is enough of the heart sill alive it will increase its effort to compensate for what died. Many people live long lives after heart attacks. It is best to catch an attack before the muscle dies and have surgery to rework blood paths to the starved muscle. Bypass and shunts have worked restoring blood flow to struggling hearts restoring health and longevity. But a dead muscle is a dead muscle so treatment before a major attack is critical.

A sticky heart valve is another term for mitral valve prolapse. Mitral valve prolapse is when one of the mitral valves swings up towards the atrium when it opens causing blood to leak back into the atrium.

No the cranium is above the heart so therefore the heart is not superior to the cranium.

The largest part of the heart is the left ventricle.

When alcohol is consumed, the heart function is increased and the ability of the heart to contract and move blood is increased

These are known as arteries. Veins carry blood to the heart. The artery known as the aorta carries blood from the heart to the body (and splits progressively into the various other arteries like the carotid artery in the neck and the femoral artery in the legs), whereas the pulmonary artery carries blood from the heart to the lungs .

Pulmonary artery (to the lungs) Aorta (to the rest of the body.)

The purpose of ventricles in the brain is to cushion and protect the brain from trauma. Ventricles are filled with Cerebral Spinal Fluid (CSF). This fluid cushions the brain and acts as a shock absorber.
