Aorta
Its actually called the atrium.Aorta
The aorta is the major blood vessel which transports blood from the heart to the rest of the body.
Aorta
The semi-lunar valves are located between the ventricles and the major arteries. There are two of them: the aortic valve and the pulmonic valve. They prevent blood from flowing backward out of the vessel back into the ventricle.
Aorta
A major blood vessel in the human body.
Left ventricle is the strongest and most important chamber of the heart. It receives oxygenated blood from left atrium, and pumps it into the aorta. Thus supplying the body with oxygenated blood. When this is said, all of the chambers are necessary for proper function of the heart.
When leaving the right ventricle during systole the blood leaves through the pulmonic semilunar valves, into the pulmonary trunk and out the right and left pulmonary arteries...heading to the lungs.
When the ventricles of your heart contract, blood is pumped out of the heart into the major arteries. The left ventricle pumps blood into the aorta, and the right ventricle into the pulmonary artery.
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.
The major arteries that take blood away from the heart are the aorta and pulmonary arteries.
The Systemic aorta is the major blood vessel that brings back blood to heart from most body parts.
