In this article, we discussed the Difference Between External Respiration and Internal Respiration of Class 10 Chapter Life Processes with a full Detailed explanation
External Respiration: It is exchange of gases that occurs at the respiratory surface. Oxygen has a higher partial pressure in the alveolar air than inside the blood circulation over the alveolar surface. Carbon dioxide has higher partial pressure in the blood as compared to alveolar air.
Internal Respiration: It is exchange of gases that occurs between blood and tissues. Blood containing oxygen or oxyhemoglobin is called oxygenated blood. From lungs the oxygenated blood. From lungs the oxygenated blood passes into left part of heart through pulmonary veins
Difference Between External Respiration and Internal Respiration
| External Respiration | Internal Respiration | |
|---|---|---|
| 1 | Place: It occurs at the respiratory surface | It occurs around the tissues |
| 2 | Gaseous Exchange: It takes place between blood and air | It occurs between blood and cells |
| 3 | Cell Respiration: It is not connected directly with cell respiration | It is connected directly with cell respiration |
