InnovateUs states that the main function of hemoglobin is transporting oxygen from the lungs to other parts of the body. It is an important chemical in red blood cells that carries oxygen, and performs different effect modulation and gas transport duties.
Through respiratory system, the oxygen enters the body and then it is transported as oxyhaemoglobin to the cells with the help of cardiovascular system. The cardiovascular system also performs the work to transport the waste product carbon dioxide to respiratory system, that evacuates it.igestive system breaks down large molecules (e.g starch) into simple molecules such as glucose. These are then transported to cells of the body via the circulatory system. The respiratory system causes the diffusion of oxygen into the blood and the diffusion of CO2 out of the blood.
