Question

Differentiate between inter respiration and external respiration

Answer 1

Answer:

Internal respiration is the gas exchange between the systemic blood and tissues.

External respiration is the gas exchange between the lungs and blood.

External respiration occurs in the lungs where oxygen diffuses into the blood and carbon dioxide diffuses into the alveolar air. Internal respiration occurs in the metabolizing tissues, where oxygen diffuses out of the blood and carbon dioxide diffuses out of the cells.

Explanation:

Answer 2

EXTERNAL RESPIRATION :-

The external respiration is a process in which living being exchanges respiratory gases (Carbon di oxide & Oxygen) from the surrounding. Thus in respiratory process oxygen comes inside the body which is called external respiration.

There are two types of external respiration -

1. Breathing
2. Exchange of gases

INTERNAL RESPIRATION :-

The gaseous exchange takes place between the blood and tissue fluid inside a body is called Internal respiration. Since, internal respiration occurs inside the cells, so it is also called Cellular respiration, while gaseous exchange takes place inside the lungs is called external respiration.

There exists various activities for the internal respiration like the following :-

1. Dissociation of Oxyhaemoglobin
2. Oxidation of food stuffs

Usually Internal respiration is of two types :-

Anaerobic respiration - When the phenomenon of respiration takes place in the absence of oxygen it is called Anaerobic respiration.

Aerobic respiration - When the phenomenon of respiration takes place in the presence of oxygen then it is called Aerobic respiration.
