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 ...

5. Coronary arteries: There are two coronary arteries right and left, arising from the base of aorta and supply blood to heart muscles, (blockage at these arteries result a myocardial infraction or heart attack). ADVERTISEMENTS: Valves in the Heart: ...
Function and Physiology of Cardiac Cycle The heart contains four chambers: left and right atria and left and right ventricle. The atria are superior to the ventricles and smaller. Atria receive blood from the veins. Ventricles receive blood from the atria and eject blood to the arteries. The ...
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 blood from the left atrium then flows into the left ventricle and out of the heart to the body via the aorta. Once the blood has supplied most of its oxygen content to the body, it picks up carbon dioxide and returns it to the placenta via the umbilical arteries. This diagram ...
