The cardiovascular system's functions are to pump blood around the body, deliver nutrients and oxygen to tissues and take waste away from tissues, according to WebMD. It achieves this by working alongside other organs, including the lungs.Continue Reading
The cardiovascular system consists of the heart plus arteries and veins that extend throughout the body, according to Medscape. Blood containing oxygen and nutrients pumps from the heart and reaches various tissues and organs throughout the body via the arteries. In addition, the cardiovascular system takes waste away from tissues and organs. Gases and nutrients exchange via the smallest components of the cardiovascular system, the capillaries, according to Medscape. This ensures tissues and organs function normally.
Through its actions, the cardiovascular system supports homeostasis, Medscape states. Homeostasis is the set of parameters the body needs to function within to stay healthy, MedicineNet highlights. The cardiovascular system may change its functions to maintain homeostasis. For example, the heart adjusts how fast it beats when someone moves more or less. If the cardiovascular system fails, organs don't receive enough oxygen to meet their basic functions, according to Medscape. This means the body doesn't have enough support to maintain metabolism, which results in a homeostatic imbalance.Learn more about Cardiac Health
