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.Know More
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 excretory system is a collection of organs tasked with removing excess nitrogen and other toxins from the body. The kidneys, liver and large intestine perform most of the filtration duties. Solid waste passes out through the colon, gaseous waste exits the body through the lungs and excess liquid leaves through the bladder and skin.Full Answer >
The main function of capillaries is enabling the exchange between water, oxygen, carbon dioxide, nutrients and many other substances between blood and the surrounding tissues. The capillaries also connect the arterioles and venules to create uninterrupted blood flow through the body.Full Answer >
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 circulatory system is important because it is transports blood and other materials throughout the body. Without the circulatory system, the body does not receive oxygen, and the heart and lungs fail to work.Full Answer >
