D

Explanation: 

Detailed explanation-1: -Red blood cells contain a protein called hemoglobin, which carries oxygen from the lungs to all parts of the body .

Detailed explanation-2: -Red blood cells carry oxygen from our lungs to the rest of our bodies. Then they make the return trip, taking carbon dioxide back to our lungs to be exhaled.

Detailed explanation-3: -The blood transports oxygen from the lungs to the cells of the body, where it is needed for metabolism. The carbon dioxide produced during metabolism is carried back to the lungs by the blood, where it is then exhaled (breathed out).

Detailed explanation-4: -red blood cell, also called erythrocyte, cellular component of blood, millions of which in the circulation of vertebrates give the blood its characteristic colour and carry oxygen from the lungs to the tissues. The mature human red blood cell is small, round, and biconcave; it appears dumbbell-shaped in profile.

Detailed explanation-5: -Blood cells pick up oxygen in the lungs. Pulmonary veins carry the oxygenated blood from the lungs to the heart’s left atrium (upper heart chamber). The left atrium sends the oxygenated blood into the left ventricle (lower chamber). This muscular part of the heart pumps blood out to the body through the arteries.
