The respiratory system is responsible for providing oxygen to all the different parts of the body. This is made of a few parts:

The mouth and nose are used to pull air inside our systems. it can also block certain things from entering the lungs.
Sinuses are used to regulate the temperature and humidity of the air inside the respiratory systems.
The throat is a tube that delivers air from our noses and mouths to the windpipe.
The windpipe is a passage that connects the throat and lungs.
Bronchial tubes are tubes that connect the windpipe to both of the lungs.
The lungs are organs that act like bellows that send oxygen through blood to all the organs and tissues.
The ribs act like a shield to protect the lungs.
The Diaphragm is a muscle that helps push and pull air in and out of the lungs.

The lungs have a few cells that help them distribute air and defend themselves. Some of these cells are:

Alveolar Epithelial Cells form tiny air sacks called alveoli, which transfer oxygen from air to the bloodstream.
Bronchiolar Epithelial Cells line the tubes that control airflow, they help redirect air to the alveoli.
Goblet Cells generate a small coating of mucus in the lungs, and this sticky paste catches debris that could damage the lungs.
