1) Exchange of gases takes place between the alveoli of lungs and the surrounding blood capillaries.
2)The two main gases exchanged are oxygen and carbon-dioxide.
3)Oxygen is absorbed by the blood capillaries from the lungs alveoli by diffusion while carbon-dioxide is absorbed by the lungs alveoli from blood capillaries by diffusion.
4)Transport of oxygen and carbon-dioxide occurs with the help of respiratory pigment called haemoglobin.
5)Haemoglobin, the iron containing respiratory pigment is a red colored pigment of blood, which has a very high affinity for oxygen.
6)Oxygen is transported from lungs to the body cells in the form of oxy-haemoglobin.
7)Carbon-dioxide is transported from the body cell to the lungs in the forms of carboxy-haemoglobin, carbonic acid, bicarbonates of sodium and potassium.

Oxygen in human beings is carried by hameoglobin which is a pigment present in red blood corpuscles .While, Carbon dioxide is transported in dissolved for forms in our blood
