Question

How is oxygen and carbon dioxide is transported in human being

Answer 1

Dear student.

Oxygen and carbon di oxide transported through Blood in human beings.

Haemoglobin present in RBC is the respiratory pigment in human beings which transport the inspired oxygen molecule. Oxygen binds with the red colour pigment known as haemoglobin in the blood and transported to different parts of the body. Once used up, the deoxygenated blood contains carbon di oxide and expels it out.

More to know:

• Alveoli are microscopic air sacs. They are the primary sites of exchange of gases. Gas exchange also occurs in lungs and tissues by diffusion.
• Atmospheric air contains little CO₂, but blood flowing in pulmonary capillaries has a higher concentration of CO₂.
• CO₂ diffuses from higher concentration in blood across walls of alveolar capillaries to lower concentration in air in alveoli.
• Blood coming into pulmonary capillaries is oxygen poor and alveolar air is oxygen rich.
• Oxygen diffuses from higher concentration in alveoli across walls of alveolar capillaries to lower concentration in blood.
