Heart

Not ALL herbivores do, four chambers are a characteristic of "ruminant" herbivores. Herbivores need to be able to get energy from plant material (a sugar called cellulose) and to do this they need to get bacteria to "ferment" the plant material they eat (they then live on the reproducing bacteria). The chambers of the stomach are where this fermentation happens.

Humans stomachs are designed to eat fruits and meat and therefor we do not need large stomachs (gorillas do because although they are not ruminants they live on plants).

Yes, the heart is an involuntary muscle. It contracts without conscious control.

it is important because the fat protects the heart from abuse and keeps it warm

Arteries are the blood vessels that carry blood away from the heart to all parts of the body. Veins are the blood vessels that carry deoxygenated blood from all body part to the heart and lungs.

the fossa ovalis was the foramen ovale and the ligamentum arteriosum was the ductus arteriosus.

They each contributed to shunting blood away from the non-functional lungs in the fetus.

The answer to that is unknown. It is also not fact, yet that the universe implodes and explodes, still theory. But in my opinion to that question, I would think, it would be untraceable.

Left coronary artery

right atrium, left atrium, left ventricle and right ventricle

The apex of the heart is lowest tip of the heart that points downward at the base. It is a where doctors often listen to the heart because it is easier to hear without other noises.

yes because then you will die if no blood is pumped through your body :P

Yes, if you have significant heart muscle damage causing chronic congestive heart failure, abnormal heart rhythms (arrhythmia), or low efficiency (ejection fraction generally <20%, normal is 55-65%).

The ventricular chambers are full with cerebrospinal fluid and are lined by neuroglia (ependymal cells).

In normal conditions, blood is pumped to the body by the left side of the heart while the right side pumps it to the lungs. Because of the tetralogy of fallot, the hole between the right and left pumping chambers allows the blood to travel across the right and left ventricles but also out into the body artery.

mean arterial pressure

Could be. Breathing is not a response. A person who is unconscious would be unresponsive and still breathing.

You have the special blood supply for your heart coming from aorta. You have left and right coronary arteries. You have two branches of left coronary artery. The left circumflex goes towards left side between the upper and lower chambers of your heart. The descending branch comes down between two ventricles on anterior side. The right coronary goes to the right side between the upper and lower chambers. The same blood vessel goes down from backside between the two ventricles. There can be individual variations. But then each and every heart cell gets the blood supply in normal course.

The third ventricle

It means "atrioventricular". It refers to the valves between the atria and the ventricles.

You mean the atrium? It passes the blood towards the ventricle. And don't be surprised; after all, the heart is just a pump, albeit a necessary one...

You'll need to be more specific, since valves are used in many different applications.

What type valves are you posting your inquiry?

Since the topic is under "new electrical work", one might assume that you are asking about electrically operated valves or valves with position sensors, or you may be asking about the old "vacuum tubes", which in much of the world are referred to as "valves".

Answering all of those questions would end up being a dissertation, and probably more than would be appropriate for Answers.com

The valves of the heart prevent the blood that is pumped out from flowing back to the heart or backward in veins.

Because all Egyptians believe that the heart means Intelligence and the dead body will need it in heaven.
