The circulatory system is also called cardiovascular system, is an organ system that permits the blood to circulate and transport nutrients. Such as amino acid and electrolites, hormones, oxygen, carbon dioxide.
The circulatory system consist of three independent system that works together [the heart or cardiovascular, lungs or pulmonary and artries, veins, coronary and portal vassal systemic]
The system is responsible for the flow of blood, nutrients, oxygen and other gasses and as well as hormones to and from the cell.
The heart is muscular organ which have four chambers. Heart is located just behind and slightly left the chest bone, it pumps blood through the network of arteries and veins called as cardiovascular system.
The systemic circulation is a major portion of circulatory system. The network of veins, arteries and blood vassals transport oxygenated blood from the heart to organs and body’s cell and then back deoxygenated blood to the heart.
An average adult have 5 to 6 quarts [4.7_5.6 liter] of blood which made up of plasma, red blood cells, white blood cells and platelets.
The system of blood vassals in human body measure about 60,000 miles [96,560 kilometers].
Arteries carry oxygen-rich from the heart to the body and veins carry oxygen-poor blood back to the heart.
The superior vana cava carries oxygen-poor blood into the heart and the aorta supplies the oxygen-rich blood to the whole body.
