Question
In human beings, where does the gaseous exchange take place?
✓
Answer
In humans, lungs are the major respiratory organ.Internally, lungs are divided into numerous sac like structures called as alveoli. respiratory is the process that occurs between oxygen and carbon dioxide. Oxygen is passed from the lungs to the bloodstream and carbon dioxide is eliminated from the bloodstream to the lungs. Exchange of Gas takes place in lungs between the alveoli and capillaries which are tiny blood vessels, placed at the walls of alveoli. The rate of diffusion depends on the thickness of the biological membrane which forms the boundary between the external environment.
