Answer:
1. The Small Intestine. The small intestine, shown in Figure 6, is where final digestion and absorption occur.
2. The transportation route to all tissues is a highly intricate blood-vessel network, comprised of arteries, veins, and capillaries. Nutrients absorbed in the small intestine travel mainly to the liver through the hepatic portal vein.
3. The oxygen enters the bloodstream from the alveoli, tiny sacs in the lungs where gas exchange takes place (Figure below). The transfer of oxygen into the blood is through simple diffusion. The oxygen-rich blood returns to the heart
4. Oxygen enters the body in the mouth and nose, passes through the larynx and the trachea. ... The capillaries take oxygen into the arteries, and the oxygen-rich blood is then pumped into every cell of your body. Once the oxygen has been absorbed, carbon dioxide and water are eliminated through the lungs.
5.Natural sources of carbon dioxide include most animals, which exhale carbon dioxide as a waste product. Human activities that lead to carbon dioxide emissions come primarily from energy production, including burning coal, oil, or natural gas.
