Deoxygenated blood spilld into the right atrium by way of the inferior and superior vena cava. The blood then funnels through the tricuspid valve and builds up in the right ventricle. With a strong contraction upward, the right ventricle pumps the blood upward through the pulmonic valve(pulmonary semilunar valve) . The blood moves through the pulmonary artery to the lungs where the exchange of carbon dioxide for oxygen takes place. Oxygenated blood then flows from the lungs into the pulmonary veins. The pulmonary veins then dumps the oxygenated blood into the left atrium. Blood funnels through the mitral valve (bicuspid valve) into the left ventricle. A powerful contraction is made to push the blood through the aortic valve(aortic semilunar valve) into the aorta where the blood is channeled throughout the body.

What is meaning of blood circuit?

A blood circuit is the pathway blood travels from the heart out of the aorta to the rest of the body (oxygenated blood), then (deoxygenated blood) returns back to the heart to be sent to the lungs to exchange CO2 for oxygen then returns back to the starting point to leave the heart through the aorta again. A blood circuit is the pathway blood takes from a certain point then eventually returning back to that point.

What is the primary pathway of the blood going to the heart?

The pulmonary artery is the primary artery going to the heart; very basically- it transports the blood below the heart. The aorta runs above the heart and is actually the largest artery, but it handles less blood as it has a smaller area to cover.

WHICH ARE THE PATHWAY THROUGH WHICH BLOOD TRAVEL AROUND THE BODY?

Veins carry the deoxygenated blood back to the heart. Arteries carry the oxygenated blood away from the heart to the body.The jugular veins bring deoxygenated blood from the head to the heart. The carotid artery supplies the head with oxygenated blood.
