Circulatory System Functions Parts Facts Britannica 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. 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.

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 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. Definition. the circulatory system, also known as the cardiovascular system, consists of the organs and fluids that transport materials like oxygen and nutrients throughout the body. all vertebrates have a closed circulatory system in which the blood plasma and cells remain within blood vessels. this is opposed to an open circulatory system in. Main features of the human circulatory system. a liquid, blood, to transport nutrients, wastes, oxygen and carbon dioxide, and hormones. two pumps (in a single heart): one to pump deoxygenated blood to the lungs and the other to pump oxygenated blood to all the other organs and tissues of the body. a system of blood vessels to distribute blood.

Circulatory System Organs And Functions Definition. the circulatory system, also known as the cardiovascular system, consists of the organs and fluids that transport materials like oxygen and nutrients throughout the body. all vertebrates have a closed circulatory system in which the blood plasma and cells remain within blood vessels. this is opposed to an open circulatory system in. Main features of the human circulatory system. a liquid, blood, to transport nutrients, wastes, oxygen and carbon dioxide, and hormones. two pumps (in a single heart): one to pump deoxygenated blood to the lungs and the other to pump oxygenated blood to all the other organs and tissues of the body. a system of blood vessels to distribute blood. The circulatory system is a system of organs that includes the heart, blood vessels, and blood which is circulated throughout the entire body of a human or other vertebrate. [1][2] it includes the cardiovascular system, or vascular system, that consists of the heart and blood vessels (from greek kardia meaning heart, and from latin vascula. 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.
