Which of these transports oxygen to every cell of the body?

Correct option is A

The correct answer is (a) R.B.C.
· Red Blood Cells (R.B.C.s), also known as erythrocytes, are the primary cells in the blood responsible for transporting oxygen.
· R.B.C.s contain hemoglobin, an iron-containing protein that binds oxygen in the lungs and releases it in tissues throughout the body.
· The structure of R.B.C.s, being biconcave and flexible, allows them to travel efficiently through the circulatory system and deliver oxygen to all body cells.
Information Booster:
· R.B.C. and hormone: Hormones are chemical messengers that regulate various functions in the body, but they do not transport oxygen.
· R.B.C and W.B.C.: White Blood Cells (W.B.C.s) are involved in the immune response and do not transport oxygen. They protect the body against infections and foreign invaders.
· W.B.C.: White Blood Cells (W.B.C.s) are not involved in oxygen transport; their primary role is in immune defense.
