What are tiny sacs where the exchange or oxygen and carbon dioxide takes place?

Alveoli are tiny sacs in the lungs where the exchange of oxygen and carbon dioxide occurs during the process of respiration. They are surrounded by a network of blood vessels, allowing for efficient gas exchange to support bodily functions.

Where does gas exchange between the air and the blood occur?

Gas exchange between the air and the blood occurs in the alveoli of the lungs. The alveoli are tiny air sacs where oxygen from the air diffuses into the blood and carbon dioxide from the blood diffuses into the air to be exhaled.
