What is the difference between pulmonary ventilation external respiration and internal respiration?
Pulmonary ventilation is the movement of air into and out of the lungs (breathing). External respiration is the exchange of O2 (loading) and CO2 (unloading) between blood and alveoli (air sacs). Internal respiration is gas exchange between blood and tissue cells.
What is internal expiration?
Internal respiration is the process of diffusing oxygen from the blood, into the interstitial fluid and into the cells. Waste and carbon dioxide are also diffused the other direction, from the cells to the blood.
What is the difference between internal and external gas exchange?
The main difference between internal respiration and external respiration is that internal respiration refers to the gas exchange across the respiratory membrane in the metabolizing tissues whereas external respiration refers to the gas exchange across the respiratory membrane of lungs.
What do inspiration and expiration have in common?
oxygen entering the body and carbon dioxide leaving the body. What do inspiration and expiration have in common? They both use the same pathways.
What is ventilation write the difference between inspiration and expiration?
Inspiration is the intake of the air into the lungs. Expiration is the expulsion of the air out of the lungs.
What’s the difference between internal respiration and external respiration?
External respiration also involves gas exchange, the exchange of oxygen and carbon dioxide between body cells and blood cells. Internal respiration is the respiration that occurs within a cell.
How are inspiration and expiration related to pulmonary ventilation?
Pulmonary ventilation comprises two major steps: inspiration and expiration. Inspiration is the process that causes air to enter the lungs, and expiration is the process that causes air to leave the lungs (Figure 22.3.3). A respiratory cycle is one sequence of inspiration and expiration.
What is the relationship between inspiration and expiration?
Pressure Relationships Inspiration (or inhalation) and expiration (or exhalation) are dependent on the differences in pressure between the atmosphere and the lungs. In a gas, pressure is a force created by the movement of gas molecules that are confined.
What are the two types of respiration in the body?
There are two main types of respiration, internal and external respiration. What are internal respiration and external respiration? Internal respiration occurs in the body tissues, where cells release carbon dioxide and take in oxygen from the blood.
