What are the 3 organs of respiratory system?

The three main organs of the respiratory system are:

1. Nose: The nose is the primary organ through which air enters the respiratory system. It helps in filtering, warming, and moistening the inhaled air. It also contains sensory receptors that allow us to smell.

2. Lungs: The lungs are the principal organs of the respiratory system, responsible for gas exchange (oxygen uptake and carbon dioxide release). They are composed of millions of tiny air sacs called alveoli, where oxygen and carbon dioxide are exchanged between the air and the bloodstream.

3. Trachea (Windpipe): The trachea is a tubular structure that connects the nose and throat to the lungs. It carries the inhaled air from the nose and throat to the lungs and transports exhaled air from the lungs out of the body.
