The transportation of oxygen and carbon (IV) oxide in mammals is carried out by
Answer Details
The transportation of oxygen and carbon dioxide in mammals is carried out by erythrocytes, which are also known as red blood cells. Erythrocytes are specialized cells that contain a protein called hemoglobin, which binds to oxygen and carbon dioxide molecules. Oxygen is transported from the lungs to the tissues of the body, while carbon dioxide is transported from the tissues back to the lungs for exhalation.
When erythrocytes pick up oxygen in the lungs, the oxygen molecules bind to the hemoglobin in the red blood cells and form a complex called oxyhemoglobin. This complex is then transported by the erythrocytes to the tissues of the body where the oxygen is released and diffuses into the cells. At the same time, erythrocytes pick up carbon dioxide molecules that are produced by the cells during cellular respiration. The carbon dioxide binds to the hemoglobin in the erythrocytes and is transported back to the lungs where it is released and exhaled.
Leucocytes, thrombocytes, and phagocytes are other types of blood cells that play different roles in the immune system and blood clotting, but they do not play a significant role in the transportation of oxygen and carbon dioxide in mammals.
