Detailed explanation-1: -So, the correct option is ‘Right auricle→ Right ventricle → Lungs→ left auricle → Left ventricle’.
Detailed explanation-2: -Blood comes into the right atrium from the body, moves into the right ventricle and is pushed into the pulmonary arteries in the lungs. After picking up oxygen, the blood travels back to the heart through the pulmonary veins into the left atrium, to the left ventricle and out to the body’s tissues through the aorta.
Detailed explanation-3: -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.
Detailed explanation-4: -right atrium → right ventricle → lungs → left atrium → left ventricle → body.
Detailed explanation-5: -Pulmonary circulation transports oxygen-poor blood from the right ventricle to the lungs, where blood picks up a new blood supply. Then it returns the oxygen-rich blood to the left atrium.
