question 14
The human circulatory system is one of the major eleven organ systems in the human body and is responsible for the circulation of blood through the body. It consists of blood, blood vessels and heart. The blood circulating through the circulatory system is responsible for the transport of oxygen and nutrients to the cells, and removal of carbon dioxide and waste from the cells. The heart is a four chambered structure that is responsible for pumping the blood into the blood vessels of the system. The two upper chambers are called right and left atria whereas two lower chambers are called right and left ventricles.
The blood vessels comprising the circulatory system are of three types: arteries, veins, and capillaries. In case of systemic circulation, the arteries are responsible for circulating oxygen rich blood from the heart to the tissues. The veins are responsible for circulating oxygen depleted blood from the tissues back to the heart. The capillaries are vessels with very thin diameter where actual exchange of gas occurs between tissues and is responsible for connection between arteries and veins.
