How does the R.S. relate to Immunity?

The respiratory is how we breath. We breath in oxygen which may sometimes contain harmful organisms. If our immune system is not strong enough to fight off the organisms then you may get sick. It is important to have a healthy immune system so if we breath in harmful things it will be able to protect us.

Relating the body's nutrients to the R.S.

Nutrients helps out the respiratory system by building up the immune system. Nutrition is a great way to a stronger immune system helping it fight off harmful diseases. When we breath we may take in some unhealthy organisms which may cause us to get sick. The more nutrients you have, the stronger your immune system will be and the more it will fight off the disease.
