Question

For efficient transport of oxygen to all cells, the body requires______.

• A. Diffusion pressure and haemoglobin
• B. Osmotic pressure and globin
• C. Blood pressure and haemoglobin
• D. Osmotic pressure and blood pressure

Answer 1

The correct option is A

Diffusion pressure and haemoglobin

When the size of an organism is large, diffusion pressure is not sufficient for oxygen transport. It is overcome by the presence of an oxygen-carrying pigment called haemoglobin which transports oxygen efficiently to all the cells of the body.
