The circulatory system (also called the cardiovascular system in mammals) of the pig is responsible for the transportation of nutrients, gases, wastes, and hormones.
Additionally, it is involved with the control of body temperature, provides channels for the immune system to protect the body, and participates in the maintenance of body fluid homeostasis.
