The immune system protects the body from infections and other external objects, whereas the circulatory system gives the body vital nutrition and resources. These two systems complement one another like peanut butter and jelly; they are each excellent on their own, but when combined, they create something truly remarkable.
To defend against health threats, your immune system uses specialized cells. Immune cells are transported by your circulatory system to their destinations, which is one of the most crucial ways it supports your immune system. These vital cells could not perform their functions properly without your arteries and blood vessels.
