The circulatory system is made up of multiple different organs, and it's main function is transportation. The system allows blood to circulate, which transports oxygen, hormones and nutrients as well as picking up waste. The elements of the system include;
The Heart
The heart acts as a muscular pump which is divided into 4 different chambers, the heart's main function is to pump the blood around the body. It pumps deoxygenated blood through the veins, to the lungs for oxygenation which can then be pumped into the various arteries. The transported blood therefore transports oxygen, hormones and nutrients to body tissues.
The four chambers in the heart are known as the right atrium, left atrium, right ventricle
