How does the circulatory system work with other body systems?
The circulatory system is an organ system that moves nutrients, gases, and wastes to and from cells, helps fight diseases and helps stabilize body temperature and pH to maintain homeostasis. This system may be seen strictly as a blood distribution network, but some consider the circulatory system as composed of the cardiovascular system, which distributes blood, and the lymphatic system, which distributes lymph. While humans, as well as other vertebrates, have a closed cardiovascular system (meaning that the blood never leaves the network of arteries, veins and capillaries), some invertebrate groups have an open cardiovascular system. The most primitive animal phyla lack circulatory systems. The lymphatic system, on the other hand, is an open system.
The circulation of the blood throughout the body is important. Certain cells found in the blood transport oxygen and carbon dioxide. Oxygen to the brain is important to its function. Blood is pumped to the heart, tissue cells take in nutrients and excrete wastes etc. It is the essential transport system that keeps blood flowing continuously for homeostatic need with in the body.
