Transport of oxygen by blood takes place with the help of (1) Erythrocytes (2) Thrombocytes (3) Lymphocytes (4) Leuecocytes

1 Answer

Answer :

(1) Erythrocytes Explanation: Red blood cells, or erythrocytes, are the most common type of blood cell and the vertebrate organism's principal means of delivering oxygen (O2) to the body tissues via the blood flow through the circulatory system. The cytoplasm of these cells is rich in haemoglobin., an iron-containing bio-molecule that can bind oxygen and is responsible for the blood's red color.
