Solution
The site of gas exchange in the human respiratory system is the Alveoli of Lungs.
Here's a step-by-step explanation:
-
When we breathe in, air enters the body through the nose or mouth and travels down the trachea (windpipe).
-
The trachea splits into two bronchi, each leading to a lung.
-
Inside the lungs, the bronchi branch out into smaller bronchioles.
-
These bronchioles end in tiny air sacs called alveoli.
-
The alveoli are surrounded by a network of tiny blood vessels, or capillaries.
-
Oxygen from the inhaled air passes through the walls of the alveoli and into the blood in the capillaries.
-
At the same time, carbon dioxide, a waste product, passes from the blood into the alveoli and is then exhaled.
-
This process of gas exchange - oxygen in, carbon dioxide out - is the primary function of the respiratory system.

Recall what happens during gas exchange in the alveoli of the lungs.
The human gas-exchanging organ, the lung, is located in the thorax, where its delicate tissues are protected by the bony and muscular thoracic cage. The lung provides the tissues of the human body with a continuous flow of oxygen and clears the blood of the gaseous waste product, carbon dioxide. Atmospheric air is pumped in and out regularly through a system of pipes, called conducting airways, which join the gas-exchange region with the outside of the body. The airways can be divided into upper and lower airway systems. The transition between the two systems is located where the pathways of the respiratory and digestive systems cross, just at the top of the larynx.T
