How is oxygen and carbon dioxide exchanged in the bronchi and lungs?

Answer 1

When air is inhaled it is brought into aveoli, which are very small sacs surrounded by capilaries. These capilaries have blood flowing through them, and oxygen diffuses into the blood and carbon dioxide diffuses out of the blood and into the lungs.

Answer 2

The exchange occurs in the lungs thanks to the hemoglobin. I a nutshell, when exposed to fresh, oxygen-rich air, the hemoglobin picks up the oxygen and releases the CO2, by undergoing a change in its shape. The affinity for the oxygen is because of the iron atom in the center of the hemoglobin. The process involves substances such as 2,3 diphosphoglycerol, change in pH and temperature. These factos affect the affinity that the hemoglobin has for oxygen.

Answer 3

When oxygen goes into the lungs it goes through different changes and turns into carbon dioxide when you let it out.

Answer 4

In the lungs are oxygen and carbon dioxide gases exchanged to facilitate the process of respiration. This happens in tiny air sacs that are known as alveoli.

Answer 5

the oxygen
