Respiration is the process by which oxygen is taken in and carbon dioxide is expelled. It is essential for the body to function properly. There are two different types of respiration, internal and external. Internal respiration occurs within the cells of the body and external respiration occurs in the lungs. While they are both essential for the body to function properly, they are different processes.

What is External Respiration?

External respiration is the process of exchanging oxygen and carbon dioxide between the air and the body’s cells. It occurs in the lungs and involves the inhalation and exhalation of air. During inhalation, oxygen is taken in from the air and transported to the cells by the bloodstream. Carbon dioxide is then exhaled from the body as a waste product.

What is Internal Respiration?

Internal respiration is the process of exchanging oxygen and carbon dioxide between the cells of the body and the bloodstream. It occurs within the cells and involves the diffusion of oxygen and carbon dioxide. Oxygen is taken in from the bloodstream and used in the cells for energy production. Carbon dioxide is then released from the cells and transported to the lungs where it is exhaled.

Difference in Process

The main difference between external and internal respiration is the process of exchange. In external respiration, oxygen is inhaled and carbon dioxide is exhaled. In internal respiration, oxygen is diffused and carbon dioxide is released. This is an important distinction as each process has a different effect on the body.

Difference in Location

The other major difference between external and internal respiration is the location of the process. External respiration occurs in the lungs and involves the inhalation and exhalation of air. Internal respiration occurs within the cells of the body and involves the diffusion of oxygen and carbon dioxide.

Difference in Function

The function of external and internal respiration also differs. External respiration provides oxygen to the cells and removes carbon dioxide from the body. Internal respiration takes the oxygen from the bloodstream and uses it to produce energy in the cells. It then releases the carbon dioxide into the bloodstream to be transported to the lungs and exhaled.

Difference in Rate

The rate of exchange between oxygen and carbon dioxide also differs between external and internal respiration. External respiration occurs rapidly and in large amounts. Internal respiration occurs slowly and in small amounts. This is because external respiration occurs in the lungs while internal respiration occurs within the cells.

Difference in Oxygen Concentration

The concentration of oxygen in the air also differs between external and internal respiration. External respiration takes place in the lungs where the oxygen concentration is relatively high. Internal respiration takes place in the cells where the oxygen concentration is relatively low.

Difference in Carbon Dioxide Concentration

The concentration of carbon dioxide also differs between external and internal respiration. External respiration occurs in the lungs where the concentration of carbon dioxide is relatively low. Internal respiration occurs in the cells where the concentration of carbon dioxide is relatively high.

Difference in Oxygen Transport

The way in which oxygen is transported also differs between external and internal respiration. External respiration involves the inhalation of oxygen which is then transported to the cells by the bloodstream. Internal respiration involves the diffusion of oxygen from the bloodstream into the cells.

Difference in Carbon Dioxide Transport

The way in which carbon dioxide is transported also differs between external and internal respiration. External respiration involves the exhalation of carbon dioxide from the lungs. Internal respiration involves the release of carbon dioxide from the cells into the bloodstream.

Difference in Energy Production

The way in which energy is produced also differs between external and internal respiration. External respiration does not produce energy. Internal respiration produces energy in the cells by using oxygen from the bloodstream.

Difference in Waste Removal

The way in which waste is removed also differs between external and internal respiration. External respiration involves the exhalation of carbon dioxide from the lungs. Internal respiration involves the release of carbon dioxide from the cells into the bloodstream.

Difference in Gas Exchange

The way gas is exchanged also differs between external and internal respiration. External respiration involves the inhalation and exhalation of air. Internal respiration involves the diffusion of oxygen and carbon dioxide.

Difference in Oxygen Uptake

The way in which oxygen is taken up also differs between external and internal respiration. External respiration involves the inhalation of oxygen which is then transported to the cells by the bloodstream. Internal respiration involves the diffusion of oxygen from the bloodstream into the cells.

Difference in Carbon Dioxide Uptake

The way in which carbon dioxide is taken up also differs between external and internal respiration. External respiration involves the exhalation of carbon dioxide from the lungs. Internal respiration involves the release of carbon dioxide from the cells into the bloodstream.

Difference in Oxygen Utilization

The way in which oxygen is utilized also differs between external and internal respiration. External respiration does not use oxygen. Internal respiration uses oxygen from the bloodstream to produce energy in the cells.

Difference in Carbon Dioxide Utilization

The way in which carbon dioxide is utilized also differs between external and internal respiration. External respiration does not use carbon dioxide. Internal respiration uses carbon dioxide from the cells to be transported to the lungs and exhaled.

Difference in Oxygen Supply

The way in which oxygen is supplied also differs between external and internal respiration. External respiration involves the inhalation of oxygen from the air. Internal respiration involves the diffusion of oxygen from the bloodstream into the cells.

Difference in Carbon Dioxide Supply

The way in which carbon dioxide is supplied also differs between external and internal respiration. External respiration involves the exhalation of carbon dioxide from the lungs. Internal respiration involves the release of carbon dioxide from the cells into the bloodstream.

Conclusion

External and internal respiration are two different processes that are essential for the body to function properly. External respiration occurs in the lungs and involves the inhalation and exhalation of air. Internal respiration occurs within the cells and involves the diffusion of oxygen and carbon dioxide. While they both involve the exchange of oxygen and carbon dioxide, they are different processes that have different effects on the body.
