It transports oxygen and other essential substances throughout the body, fights sickness, and performs other vital functions. Blood is a living fluid. Human cardiovascular system, organ system that conveys blood through vessels to and from all parts of the body, carrying nutrients and oxygen to tissues and removing carbon dioxide and other wastes. There are several different circuits contained in the cardiovascular system. This system contains two fluids, blood and lymph, and functions by means of two interacting modes of circulation, the cardiovascular system and the lymphatic system; both the fluid components and the vessels through which they flow reach their greatest elaboration and specialization in the mammalian systems and, particularly, in the human body. As mentioned several times, the circulatory system has several functions in addition to transporting nutrients. Health Information, Just for Your Health. It is a closed tubular system in which the blood is propelled by a muscular heart.

The removal of waste and toxins is a function performed by the lymphatic system. Using the network of arteries, veins and capillaries, blood carries carbon dioxide to the lungs (for exhalation) and picks up oxygen. All those "roads" are veins, arteries and capillaries that carry the blood from the major artery all the way out to the small capillaries. Veins deliver used blood from the body back to the heart. The cardiovascular system helps regulate the temperature with the following: Balancing the fluids in the body means that every cell gets the proper amount of electrolytes, nutrients and gases. This amazing muscle produces electrical impulses through a process called cardiac conduction.These impulses cause the heart to contract and then relax, producing what … The main function of the cardiovascular system is to transport nutrients, waste products and gases around the body. The materials carried by the cardiovascular system include oxygen from the lungs, nutrients from the digestive system, hormones from glands of the endocrine system, and waste materials from cells throughout the body. All vertebrates have a closed circulatory system in which the blood plasma and cells remain within blood vessels. © 2020 Houghton Mifflin Harcourt.

Your heart is divided into four chambers. The heart and circulatory system make up your cardiovascular system. Oxygen is bound to molecules called haemoglobin that are on the surface of the red blood cells in the blood. That blood travels through a complex system of arteries, veins and capillaries. Blood Vessel Structure and Function: How the Circulatory Network Helps Fuel the Entire Body There are three main types of blood vessels in 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.
