Airways, Lungs, Blood Vessels, Muscles

The respiratory system includes all the organs and structures involved in breathing, which is the process of bringing oxygen into the body and expelling carbon dioxide. The main organs of the respiratory system are:

1. Nose and nasal cavity: The nose is the primary entrance for air into the respiratory system. The nasal cavity filters, warms, and moistens the air as it flows through.

2. Trachea: The trachea, or windpipe, is a tube that runs from the back of the throat to the lungs, providing a passageway for air.

3. Bronchi: The bronchi are two tubes that branch out from the trachea and enter each lung. They further divide into smaller passageways known as bronchioles.

4. Lungs: The lungs are the main organs of the respiratory system, responsible for receiving and exchanging oxygen and carbon dioxide. There are two lungs, one on each side of the chest.

5. Alveoli: The alveoli are tiny air sacs within the lungs where gas exchange between the air and blood takes place.

6. Diaphragm: The diaphragm is a dome-shaped muscle located at the bottom of the chest that plays a key role in breathing by contracting and relaxing to expand and contract the lungs.
