the stucture of the circulatory system is to the circulatory - or cardiovascular - system carries blood that is low in oxygen away from the heart to the lungs via veins, where oxygen levels are restored through the air which we breath in; once oxygenated, this blood is then carried throughout the body via arteries, keeping our organs and tissue alive.
It consists of the heart, which powers the whole process; the veins and arteries; and capillaries, which deliver oxgen to tissue at the cellular level.
The circulatory system is an organ system that passes nutrients (such as amino acids, electrolytes and lymph), gases, hormones, blood cells, etc. to and from cells in the body to help fight diseases, stabilize body temperature and pH, and to maintain homeostasis.
