In which part of the human body does gas exchange primarily occur?
Correct Answer: Alveoli
Step 1: Understand that gas exchange is the process of taking in oxygen and getting rid of carbon dioxide.
Step 2: Know that this process happens in the lungs, which are the organs responsible for breathing.
Step 3: Learn that within the lungs, there are tiny structures called alveoli.
Step 4: Recognize that alveoli are small air sacs where oxygen from the air enters the blood and carbon dioxide from the blood is released into the air.
Gas Exchange – The process by which oxygen is taken into the body and carbon dioxide is expelled, primarily occurring in the alveoli of the lungs.
Alveoli – Tiny air sacs in the lungs that facilitate the exchange of gases between the air and the bloodstream.
