Question

The image shows the transport of gases in body through heart and lungs. Which option correctly shows the transport of oxygen to the cell?

Lungs-pulmonary vein-left atrium-left ventricle → aorta →

body cells

Lungs-pulmonary vein-right atrium-right ventricle body cells 1 aorta->

Lungs-pulmonary artery-left atrium → left ventricle → vanacava → body cells

Lungs-pulmonary artery → right atrium right ventricle- vanacava

body cells​

Answer 1

• The transportation of blood :-

• Lungs-pulmonary vein-left atrium-left ventricle → aorta - blood vessels - vanacava -right atrium - right venticles -pulmonary artery ।

Answer 2

The correct answer will be option A

• Lungs→pulmonary vein-→left atrium→left ventricle → aorta → body cells

• Oxygenated blood from lungs reaches  left atrium through pulmonary veins,from where the blood goes into the left ventricle.

• Aorta arises from the left ventricle ,so the blood from left ventricle moves through the aorta and finally to the body cells.

• Aorta has semilunar valves which prevent the backflow of bloof into the left ventricle.
