What is the role of respiratory pigment in respiration? |
| Answer» Animals have large body size due to which, the diffusion pressure alone cannot deliver oxygen to all parts of the body.Therefore, the respiratory pigments take up oxygen from the lungs and carry it to the tissues, which are deficient in oxygen before releasing it.Haemoglobin is one such respiratory pigment found in the Red Blood Cells (RBCs) of human beings. | |
