Systemic circulation is the portion of the cardiovascular system which carries oxygenated blood away from the heart, to the body, and returns deoxygenated blood back to the heart.Īrteries always take blood away from the heart, regardless of their oxygenation, and veins always bring blood back. The cardiovascular system and the lymphatic system collectively make up the circulatory system. The lymph, lymph nodes, and lymph vessels form the lymphatic system. The blood, heart, and blood vessels form the cardiovascular system. Two types of fluids move through the circulatory system: blood and lymph. An average adult contains five to six quarts (roughly 4.7 to 5.7 liters) of blood, which consists of plasma that contains red blood cells, white blood cells, and platelets. The circulatory system includes: the pulmonary circulation, a "loop" through the lungs where blood is oxygenated and the systemic circulation, a "loop" through the rest of the body to provide oxygenated blood. The main components of the human circulatory system are the heart, the blood, and the blood vessels. The lymphatic system, on the other hand, is an open system. The most primitive animal phyla lack circulatory systems. 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. 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. 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. Red indicates oxygenated blood, blue indicates deoxygenated. Īssociate Editor-In-Chief: Cafer Zorkun, M.D., Ph.D. List of terms related to Circulatory systemĮditor-In-Chief: C.

The blood then continues through the rest of the body before arriving back at the atrium this is called systemic circulation. The atrium collects blood that has returned from the body and the ventricle pumps the blood to the gills where gas exchange occurs and the blood is re-oxygenated this is called gill circulation. \)a Fish have a single circuit for blood flow and a two-chambered heart that has only a single atrium and a single ventricle.
