Question

what are respiratory pigments? why do larger animals need respiratory pigments​

Answer 1

Answer:

What Is a Respiratory Pigment? A respiratory pigment is any molecule that increases the oxygen carrying capacity of blood. The oxygen carrying capacity is simply the amount of oxygen the red blood cells in our blood can carry to our tissues and organs.

Answer 2

Answer:

Because as the body size of the animals are larger, diffusion pressure cannot take care of the oxygen deliveries to all parts of the body.Hence respiratory pigments will take the oxygen in the air in the lungs and carry it to the tissues which are deficient in oxygen.In humans haemoglobin is the respiratory pigment present in the red blood corpulses
