NEET BIOLOGY

Detailed explanation-1: -The right ventricle pumps the blood to the lungs where it becomes oxygenated. The oxygenated blood is brought back to the heart by the pulmonary veins which enter the left atrium. From the left atrium blood flows into the left ventricle.

Detailed explanation-2: -The heart pumps deoxygenated blood from the right ventricle to the lungs and at the same time pumps oxygenated blood from the left ventricle into the aorta.

Detailed explanation-3: -The right atrium receives oxygen-poor blood from the body and pumps it to the right ventricle through the tricuspid valve. The right ventricle pumps the oxygen-poor blood to the lungs through the pulmonary valve.

Detailed explanation-4: -Pulmonary circulation is the system of transportation that shunts de-oxygenated blood from the heart to the lungs to be re-saturated with oxygen before being dispersed into the systemic circulation.

Detailed explanation-5: -The right ventricle pumps the oxygen-poor blood through the pulmonary valve to the lungs. The left atrium receives oxygen-rich blood from the lungs and pumps it through the mitral valve to the left ventricle. The left ventricle pumps the oxygen-rich blood through the aortic valve out to the rest of the body.
