Major Functions of the Cardiovascular System. The cardiovascular system consists of the heart, which is an anatomical pump, with its intricate conduits (arteries, veins, and capillaries) that traverse the whole human body carrying blood.The blood contains oxygen, nutrients, wastes, and immune and other functional cells that help provide for homeostasis and basic functions of human cells and organs. It is a closed tubular system in which the blood is propelled by a muscular heart. To protect the body from infection and blood loss 3. Your heart works as a pump that pushes blood to the organs, tissues, and cells of your body. The main function of the circulatory (or cardiovascular) system is to deliver oxygen to the body tissues, whilst simultaneously removing carbon dioxide produced by metabolism. Responsible for transporting oxygen, nutrients, hormones, and cellular waste products throughout the body, the cardiovascular system is powered by the body’s hardest-working organ — the heart, which is only about the size of a closed fist. Now, picture the small roads that branch off that major highway, the ones that lead to small town. Describe the general features of the heart. Digested nutrients are absorbed into the bloodstream through capillaries in the villi that line the small intestine. The blood also carries nutrients, hormones, waste products and sometimes medications through the body. To help maintain fluid balance within the body The primary function of the heart and blood vessels is to transport oxygen, nutrients, and byproducts of metabolism. This system causes heart muscle depolarization in only one direction- from the atria to the ventricles; it enforces a contraction rate of approximately 75 beats per minute on the heart, thus the heart beats as a coordinated unit. The right ventricle and atrium are where blood is received from the veins. The circulatory system transports blood throughout the body. The cardiovascular system, also called the circulatory system, is the organ system that transports materials to and from all the cells of the body. of body temperature, fluid pH, and water content of cells. It provides all the living cells of the organism with the materials required for their normal functions (e.g., O2 and nutrients) ... by way of the interstitial (extracellular) fluid. Arteries carry blood away from the heart and veins carry blood back to the heart. Circulatory system. The removal of waste and toxins is a function performed by the lymphatic system. more muscular than the right ventricle. Clotting mechanisms are also present that protect the body from blood loss after injuries. Regulation of body temperature, fluid pH, and water content of cells. The cardiovascular system is a transportation system that delivers blood, nutrients, ions, gases and heat throughout our bodies. Your blood vessels might also constrict or expand, thus allowing more or less of the body's fluids to be lost through sweat. 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. Your heart and circulatory system works together to deliver blood to your organs so they can function.. The systemic circulation can also be seen to function in two parts – a macrocirculation and a microcirculation. bookmarked pages associated with this title.
