Hello Manohar!
Your question is not clear. So I shall try to explain the concept to you in general.
Internal Respiration is the process of exchanging of gases from blood to the tissue cells . During internal respiration, the diffusion of gases occurs between the two, depending on the concentration of gases. After inhalation, the blood will be rich in oxygen and has higher concentration of oxygen than tissues. So oxygen will be diffused from blood to tissue cells. This oxygen will be used by cells in release of energy by breaking carbohydrates called cellular respiration . The carbon dioxide that is in excess concentration in tissues will diffuse into blood. From the blood, this carbon dioxide will be expelled to the outside environment through alveoli of lungs. This interaction of gases between body and external environment is called external respiration.
Hope this helps!
