Which process primarily involves the exchange of gases between the alveoli and the blood?
Understand the Problem
The question is asking about the specific process that deals with the exchange of gases between the alveoli in the lungs and the blood, which is typically known as external respiration.
Answer
External respiration primarily involves the exchange of gases between the alveoli and the blood.
The exchange of gases between the alveoli and the blood is primarily facilitated by diffusion, and this process is known as external respiration.
Answer for screen readers
The exchange of gases between the alveoli and the blood is primarily facilitated by diffusion, and this process is known as external respiration.
More Information
In the respiratory system, oxygen diffuses from the alveoli into the blood, while carbon dioxide diffuses from the blood to the alveoli. This is essential for maintaining the body's oxygen supply and removing carbon dioxide.
Tips
A common mistake is confusing external respiration with cellular respiration. Cellular respiration occurs within cells and involves the use of oxygen to produce energy. External respiration is strictly about the exchange of gases between the alveoli and the blood.
