Statement 1: During pulmonary circulation, the oxygenated blood moves from the right ventricle towards the lungs for reoxygenation.​

Statement 2: During systemic circulation, the oxygenated blood moves from the left ventricle to the rest of the body through the aorta.​

Q. Assertion :Pulmonary circulation consists of flow of deoxygenated blood from right ventricle to the lungs and flow of oxygenated blood from lungs to the left atrium. Reason: Systemic circulation consists of flow of oxygenated blood from the left ventricle to all parts of the body and deoxygenated blood from different parts to right atrium.

Q.

During systemic circulation, deoxygenated blood flows from right ventricle of heart to lungs.

Q. Read the statements and select the option which best describes the process that occurs during systematic circulation.
(i) The left atrium receives the oxygenated blood through the pulmonary veins. The left ventricle pumps the blood through the aorta to various parts and the de-oxygenated blood reaches right atrium.
(ii) The left atrium receives the oxygenated blood through pulmonary veins and pumps the blood through the aorta to various parts and the de-oxygenated blood reaches the right atrium.
(iii) The left atrium receives de-oxygenated blood and pumps into left ventricles which in turn pumps into pulmonary artery for oxygenation.
(iv) The right atrium receives the de-oxygenated blood and pumps into pulmonary artery for oxygenation.

Q. Which of the following statement(s) wrong with regard to heart?
A. Left atrium receives deoxygenated blood from different parts of the body while right atrium receives deoxygenated blood from the lungs.
B. Right atrium receives deoxygenated blood from different body parts while right ventricle pumps deoxygenated blood to the lungs.
C. Left atrium receives oxygenated blood from lungs while left ventricle pumps oxygenated blood to different parts of the body.
D. Pulmonary vein carries deoxygenated blood to the lungs and pulmonary artery brings oxygenated blood towards the heart.

Q. Mark the statements as true or false.

A. Systemic circulation starts from the left ventricle and ends in the right atrium.

B. Pulmonary circulation starts from the right ventricle and ends in the left atrium.
