Respiratory System

The respiratory system is important to the body's function because we need oxygen to live and this system brings oxygen into the body and gets rid of carbon dioxide.

Organs in the Respiratory System

Nose and Nasal Cavity- The nose forms the main opening for the respiratory system to let you breathe in oxygen and exhale carbon dioxide. The nasal cavity filters air entering the body before it reaches the lungs. Hairs and mucus inside  the nasal cavity helps trap dust, mold, and pollen before they can reach the inner portions of the body.

Bronchi-  The bronchi is the passageway through which air enters the lungs. They are two branches that the trachea breaks into.

Alveoli-  The alveoli is surrounded with blood capillaries, so that the exchange of oxygen and carbon dioxide can occur.

Pharynx- The pharynx is a passageway that air and food pass to get to the lungs and stomach. It has tonsils which trap and kill bacteria that comes in with the air.

Trachea- The trachea or windpipe connects the pharynx to your lungs, providing  a clear pathway for air to enter and exit the lungs.

Diaphragm- The diaphragm causes your chest to expand and contract which helps you inhale and exhale.

Lungs- The are two lungs in your body. After the oxygen gets to your lungs, it is absorbed into the bloodstream and carried throughout the body. The bloodstream then brings carbon dioxide back to the lungs, which you remove by exhaling.
