The main function of the circulatory system is to move blood and lymph through the body. Doing this transports nutrients and oxygen to the cells of the body and removes waste products such as carbon dioxide. The circulatory system is necessary to regulate temperature and pH balance and protect the body from diseases.Continue Reading
One primary function of the circulatory system is the transport of oxygen from the lungs to the cells. This is why the system has two basic parts: the pulmonary circulation, which takes blood to the lungs to pick up oxygen, and systemic circulation, which takes the oxygenated blood throughout the body. Along the way, the blood picks up nutrients, attacks diseases and gathers waste for eventual elimination.
Though some scientists separate the cardiovascular and the lymphatic systems, since both systems operate using the same biological pathways, many scientists categorize them together as the circulatory system. Although all vertebrates, such as mammals, birds and reptiles, as well as annelids and cephalopods, have closed circulatory systems, in which the blood travels through vessels to organs and back to the heart, other animals, such as mollusks, have open circulatory systems in which the blood bathes the organs directly. However, in both types of circulatory systems, the purpose is the same: to get nutrients to the cells and ferry waste away from the cells.Learn more about Human Anatomy
The main function of the circulatory system is transporting blood, oxygen, hormones, nutrients and other important substances throughout the body. The circulatory system is actually two separate systems of circulation, pulmonary and systemic, both of which interact with the heart and cardiovascular system to pump blood throughout that system.Full Answer >
The main function of the cardiovascular system is to transport nutrients, waste products and gases around the body. Moreover, it protects the body from blood loss and infection, helps the body keep a constant body temperature and helps maintain fluid balance. It serves as an internal road network that links all body parts.Full Answer >
The dorsal blood vessel is part of the circulatory system of the earthworm that carries blood to the front of its body. It is a single structure that runs along the back of the worm's body.Full Answer >
The heart draws oxygenated blood from the lungs and distributes it to the rest of the body using a system of arteries and veins. Small coronary arteries and the pulmonary veins provide oxygenated blood into the heart. The pulmonary artery then pumps deoxygenated blood to the lungs where it is resupplied with oxygen.Full Answer >
