The Respiratory System
By: Jenna Grant
What is the Importance of the Respiratory System Dealing with Immunity?
The respiratory system acts as a filter for the air you breathe. It keeps dust, pollen, pollen, and bacteria out of the lungs by producing mucus that traps these unwanted particles out of your body. For example, when you come down with the common cold, your mucus production increases to fight off the virus and keep it out of your system and helps you to heal. There are immune tissues along the way of the respiratory system, such as the tonsils, to protect you also.
How does the body's use of nutrients relate to the Respiratory System?
The respiratory system and the digestive system work in several ways to provide energy to the body's cells. In order for the digestive tract to break up food, it requires contractions of the intestine. Oxygen is needed in the smooth muscle in order for it to contract. Therefore without oxygen, your digestive tract would stop working and you would not be able to digest food and gain nutrients.
