Give an example of two other body systems that work together, and explain how they support each other.

A good example is pulmonary system and the circulatory system.

The body needs oxygen. The respiratory system is where we get the oxygen supply. When it enters our lungs, how does it go around? This is where the circulatory system comes in.  When blood enters our lungs, it picks up the oxygen we need. The primary function of the blood is to distribute nutrients, hormones, and Oxygen to the other cells of the body. Another important function of blood is to remove wastes from the cell like carbon dioxide. The carbon dioxide is brought to the lungs which we will expel when we exhale.
