"The circulator system is an organ system that passes nutrients, gases, hormones, blood cells, etc. to and from cells in the body to help fight diseases and help stabilize body temperature and ph to maintain homeostasis."

1. The circulatory system impacts the cardiovascular system by transporting oxygen depleted blood away from the heart, to the lungs, and returns oxygen rich blood back to the heart.
2. Numerous hormones (endocrine system) that help maintain constant internal conditions are transported by the circulatory system.
3. The circulatory system contains cells that fight infection, thus impacting the immune system.
4. The circulatory system helps maintain body temperature by transporting heat.
5. "Glucose a simple sugar used to produce ATP, is transported throughout the body by the circulatory system. Immediately after digestion, glucose is transported to the liver. The liver maintains a constant level of glucose in the blood."
6. After digestion, the circulatory system carries nutrients to the tissues to use and it disposes of waste.
