Explanation:

The respiratory system refers to the series of processes that begin with the inhalation of air and its movement across the blood vessels and eventual discharge from the body. Oxygen which is a very important gas needed to sustain life is inhaled during respiration. It is also circulated through the circulatory system to the cells and tissues that need it.

Taking care of these systems through exercise, rest, and eating the right foods will protect us from diseases that affect them such as Heart attack. Cells would also function well and not die easily because they can access the oxygen needed for them to thrive. The right balance of these gases would also ensure that the proper pH of the body is being maintained.
