Circulatory

= The Circulatory system by Atum and Joely =

The Circulatory system is an organ system that passes nutrients examples such as amino acids, electrolytes and lymph. also gases, hormones, blood cells, etc, etc. to and from cells in the body to help fight diseases and help stabilize body temperature and pH to maintain homeostasis.

This system may be seen strictly as a blood distribution network, but some people consider the circulatory system as composed of the **Cardiovascular System**, wich distributes blood, and the Lymphatic system, which distributes Lymph. While humans and other vertebrates have closed cardiovascular systems, meaning that the blood never leaves the network of arteries,veins and capillaries. some invertebrate groups have have an open cardiovascular system. The most primitive animal phyla lack circulatory systems. The lymphatic system but on the other hand is an open system. 2 types of fluid pass move through the circulatory system: blood and lymph.The blood, heart, and blood vessels ford the cardiovascular system. The lymph, symph nodes and lymph vessels form the lymphatic system. The cardiovascular system and the lymphatic system collectively make up the circulatory system. here are some cool links Muscles and Nervous System [|circulatory facts] [|more facts] here are some cool video links [|circulatory video] and[| circulatory song]
