What is conducting system of the heart description of the components of the conducting system of the heart site and function?
The cardiac conduction system is the conducting system of the heart.
How do the arteries aid the heart in pumping blood?
The arteries are the blood vessels which take oxygenated blood from the heart and to the rest of the body. The main artery is the aorta which then branches off into smaller arteries, then these eventually break off into even smaller vessels called arterioles which contol the amount of blood supplied to individual tissues. From arterioles branch capillaries which arethe site of exchange between the blood and the cells. Once the body tissues have used all the oxygen and nutrients in the blood, it is returned to the heart by the veins. The aorta aids in pumping because it is highly elasticated and so acts like a capacitor. It takes all the blood form the ventricle as a burst which stretched its walls out. The walls then squeeze back down pushing the blood along more continuously.
What chamber of the heart has the highest probability of being site of myocardial infraction?
Left Ventricle
What is the site www.x-overprofiles.com?

You can create your profile, upload photos, create your own blogs, post and watch videos, and chat with your friends live, all in one stop. It truly is a social networking site that connects YOU to the world.
Is the main purpose of the heart to oxygenate blood true or false?
False in general as it is only indirectly that blood pumped by the heart is oxygenated. The heart is primarily a pump. Blood pumped to the lungs picks up oxygen (becomes oxygenated) and disposes of carbon dioxide. Oxygen diffusing from the alveoli of the lungs is the true site of oxygenation. Thus the heart's pumping only gives blood the route to the lungs, the site of oxygenation. The heart has no oxygenation powers of its own.
The aorta connects to the heart at the site of the what valve?
The valve in this area is one of the semilunar valves called the aortic valve. These valves look like 3 little cups that collapse and allow blood flow from the left ventricle into the aorta (and from there it supplies a lot of your tissues and organs) when the heart pumps. After the blood moves into the aorta, the little cups expand and prevent the back-flow of blood back into the heart from the aorta.

Heart excitation originates in the what?
The atrioventricular node is the site of heart excitation. It electrically connects and coordinates the atrial and ventricular chambers at the top of the heart.
How does an Artificial heart valve work?
I can't answer this, that's why I asked this site, but obviously this site is stupid,so shove that in your pipe!
Site where resistance to blood flow is greatest?
Veins hold the greatest volume of blood in the body--------and the heart along with the nerve glands in your throat.....
Where can you find coronary circulation?
Coronary Circulations is the blood supply to the heart. The major arteries of the coronary supply are listed below. The supply to the heart is strange, in that blood only flows through its arteries during ventricular diastole (when the ventricles relax). This happens because of the Aortic valve, which stops backflow of blood from the aorta to the left ventircle. The valve is, in essence, a flap that sits over the opening to the aorta so that when the heart is relaxed the aortic blood will push againts it and hold it down, but when the veinctricla contract the flap is forced up and open to allow flow out of the ventricle. The very first arter from the aorta is the one supllying the heart (the Coronary Artery). It comes from the aorta just after the aorta come from the heart. For this reason it is blocked by the flap of skin during systole (contraction). When diastole occurs the flap is no longer pushed up so it no longer blockes the coronary supply. This is somewhat hard to explain in words and I am not aware of any way to add diagrams to this site yet but i hope this helped, or at least i hope you found it interesting. Main arteries of the heart (very abreviated): Left Coronary; Right Coronary; Right Marginal; Left Marginal; Anterior Inverventricular; Posterior Interventricular.

Where is the pcv valve located on a 1997 Plymouth breez?
The PCV valve is located on a long semi-rigid black tube that runs from the top of the valve cover, between the pipes on the intake manifold, and then finally connects to the actual intake manifold itself. As you are facing the motor with the hood up, it will be to the left of the breather/intake plastic black box. Toy have to look behind the manifold pipes to find it. Autzone's web site repair gude has a great picture of it!
