The ventricles send the blood outside the heart, whether to the lungs or other parts of the body. The left ventricle sends oxygenated blood to other areas of the body via the aorta, an artery that connects to other main arteries.Order of Blood Flow Through the Heart The Rol...
The human heart beats, at the rate of about 70- 72 per minute at rest. Every time the heart pumps blood into arteries, they distend rhythmically. This rhythm or wave can be felt and counted in the superficial and radial arteries near the wrist (Fig. 1.13). This count r...
On the outside, the heart is made of muscle. The strong muscular walls contract (squeeze), pumping blood to the arteries. The cardiovascular system is made up of your heart and your blood vessels. This heart anatomy diagram shows that blood flows from the right atrium into the right ventric...
Arteries are smooth on the inside and tough on the outside. Their muscular wall helps the heart to pump blood. When the heart beats, the arteries expand and get filled with blood. When the heart relaxes, contraction of the arteries takes place, which exert enough force to push the blood ...
