Circulatory System
The circulatory system is an organ system that passes nutrients (such as amino acids, electrolytes and lymph), gases, hormones, blood cells, etc. to and from cells in the body to help fight diseases,
stabilize body temperature and pH, and to maintain homeostasis.
The most primitive animal phyla lack circulatory systems. The lymphatic
system, on the other hand, is an open system providing an accessory route for
excess interstitial fluid to get returned to the blood.
Two types of fluids move through the circulatory system: blood and lymph.
Lymph is essentially recycled blood plasma after it has been filtered from the
blood cells and returned to the lymphatic system.
The blood, heart, and blood vessels form the cardiovascular system. The lymph, lymph nodes, and
lymph vessels form the lymphatic system.
