Flowchart Of How Blood Passes Through The Heart

Blood enters the heart through two large veins the inferior and superior vena cava emptying oxygen poor blood from the body into the right atrium of the heart. Blood leaves the svc and the ivc and enters the right atrium ra 3. Then the ventricles immediately contract to force blood into the blood vessels.

With most of the blood from the atria now in the ventricles the atria contract to squeeze any remaining blood down into the ventricles.

Flowchart of how blood passes through the heart. This period of contraction in the heart muscle is called systole. The oxygenated blood then passes into the left ventricle via the left atrioventricular valve l av mitral or bicuspid valve. From your pulmonic valve blood travels to the pulmonary artery to tiny capillary vessels in the lungs. Here oxygen travels from the tiny air sacs in the lungs through the walls of the capillaries into the blood.

The heart is made of four chambers which receive and pump blood. As the atrium contracts blood flows from your. Right side of the heart. Blood flow through the heart beginning with the superior and inferior vena cavae and the coronary sinus the flowchart below summarizes the flow of blood through the heart including all arteries veins and valves that are passed along the way.

At the same time carbon dioxide a waste product of metabolism passes from the blood into the air sacs. Blood enters the heart through two large veins the inferior and superior vena cava emptying oxygen poor blood from the body into the right atrium. When the heart beats the ventricle pushes blood through the pulmonic valve into the pulmonic artery. The ivc collects blood from the lower half of the body.

All blood enters the right side of the heart through two veins. Superior and inferior vena cavae and the coronary sinus. The superior vena cava svc and the inferior vena cava ivc see figure 3. The blood first enters the right atrium.

The path of blood through the heart also makes up a major part of the circulation because the heart also needs to be nourished and this is where both oxygenated and deoxygenated blood flow. The right atrium receives deoxygenated blood through the superior and inferior vena cavas from the body and pumps it to the right ventricle through the tricuspid valve which opens to allow the blood flow through and closes to prevent blood backing up the atrium. As the atrium contracts blood flows from your right atrium into your right ventricle through the open tricuspid valve. Arteries generally transport oxygen rich blood.

The svc collects blood from the upper half of the body. It then flows through the tricuspid valve into the right ventricle. Stage 7 the left ventricle contracts pushing the blood through the aortic semi lunar valve through the ascending aorta aortic arch descending aorta and then out to the body.
