The Respiratory System

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.
