Question

how is oxygen transported in large multicellular organisms like humans?​

Answer 1

Answer:

in large multicellular organisms like humans,the body size is large, so the diffusion pressure alone cannot take care of oxygen delivery to all parts of the body. In multicellular organisms respiratory pigments take up oxygen from the air in the lungs and carry it to the tissue which are deficient in oxygen before releasing it. In human beings, the respiratory pigment is hamoglobin which has a very high affinity for oxygen. This pigment is present in the red blood corpuscles
