Detailed explanation-1: -A blood clot in the left leg would first enter the venous system to drain back towards the heart, first encountering the vena cava. A clot would flow from the vena cava to the right atrium, to the right ventricle, to the lungs, left atrium, left ventricle and finally the aorta.

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: -Oxygen-poor blood from all over your body enters your right atrium through two large veins, your inferior vena cava and superior vena cava. Your tricuspid valve opens to let blood travel from your right atrium to your right ventricle.

Detailed explanation-4: -the correct answer is 3. vena cava-right atrium-right ventricle-lungs-left atrium-left ventricle-aorta .

Detailed explanation-5: -The blood first enters the right atrium. The blood then flows through the tricuspid valve into the right ventricle. When the heart beats, the ventricle pushes blood through the pulmonic valve into the pulmonary artery. The pulmonary artery carries blood to the lungs where it “picks up” oxygen.
