Book Lungs
A respiratory unit refers to a functional component of the lungs where gas exchange takes place. It consists of respiratory bronchioles, alveolar ducts, and alveoli, allowing for the exchange of oxygen and carbon dioxide between the air and the blood. This process is essential for maintaining adequate oxygen levels in the body and removing waste carbon dioxide.
Gas exchange between oxygen and carbon dioxide takes place in small sacs called alveoli, which are located at the end of the respiratory bronchioles in the lungs. This is where oxygen from the air is transferred into the bloodstream and carbon dioxide is removed from the blood.
The largest organ of the respiratory system is the lungs. This is where the exchange of oxygen and carbon dioxide occurs during breathing.
The function of the respiratory system is to allow gas exchange it, taking oxygen into the blood and removing carbon dioxide from the blood. The oxygen absorbed is used by the body cells to carry out respiration, the release of energy from food: sugar + oxygen ----> water + carbon dioxide + ENERGY The carbon dioxide made by respiration is removed when we breathe out.
The respiratory system is responsible for exchanging oxygen and carbon dioxide between the body and the environment. This process primarily occurs in the lungs where oxygen is taken in and carbon dioxide is expelled. Other organs involved include the nose, trachea, and bronchial tubes.

Carbon dioxide
Respiratory gas exchange is the diffusion of both carbon dioxide and oxygen from the capillaries to the alveoli in our lungs, and vice versa.

The main function of the respiratory system is the exchange of gases. It brings in oxygen and elmiinates carbon dioxide.
