Circulatory System Functions Parts Facts Britannica The circulatory system works thanks to constant pressure from the heart and valves throughout the body. this pressure ensures that veins carry blood to the heart and arteries transport it away. The human circulatory system possesses a body wide network of blood vessels. these comprise arteries, veins, and capillaries. the primary function of blood vessels is to transport oxygenated blood and nutrients to all parts of the body. it is also tasked with collecting metabolic wastes to be expelled from the body.
Diagram Of The Human Circulatory System 15.3a: anatomy of human circulatory system. the circulatory system is an organ system that permits blood to circulate and transport nutrients (such as amino acids and electrolytes), oxygen, carbon dioxide, hormones, and blood cells to and from the cells in the body to provide nourishment and help in fighting diseases, stabilize temperature and. The circulatory system (cardiovascular system) pumps blood from the heart to the lungs to get oxygen. the heart then sends oxygenated blood through arteries to the rest of the body. the veins carry oxygen poor blood back to the heart to start the circulation process over. your circulatory system is critical to healthy organs, muscles and tissues. The circulatory system, also called cardiovascular system, is a vital organ system that delivers essential substances to all cells for basic functions to occur. also commonly known as the cardiovascular system, is a network composed of the heart as a centralised pump, blood vessels that distribute blood throughout the body, and the blood itself. The systemic circulation is a major portion of the circulatory system. the network of veins, arteries and blood vessels transports oxygenated blood from the heart, delivers oxygen and nutrients to.

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. even at rest, the average heart easily pumps over 5 liters of blood throughout the body every minute. The heart is a muscular organ responsible for the flow of blood in the body. the heart has a right and a left side, each with an upper chamber (atrium) and lower chamber (ventricle). the right atrium receives oxygen deprived blood from the body. the blood travels across the tricuspid valve into the right ventricle, which pumps the blood across.
