Circulatory System Notes
The human circulatory system is one of the most important systems in the human body. By interacting with nearly every other body system it helps our body maintain homeostasis with the outside environment.
To maintain homeostasis with its external environment the lungs transport the gases Oxygen (O2) and Carbon Dioxide (CO2) to and from your lungs, nutrients from the food you eat, electrolytes, wastes, and hormones to and from every cell in your body. It also helps the body regulate its internal temperature and fight off diseases and infections
