MT 30 LAB – H 3 years, 9 months ago The circulatory system pumps blood from the heart and lungs to the different parts of the body to send oxygen-rich blood to organs. The heart pumps oxygenated blood through the arteries to the different organs of the body. The veins then collect the used-up deoxygenated blood and sends it back to the heart to be reoxygenated. The capillaries are the smallest blood vessels that connect small arteries and small veins and allow oxygen and carbon dioxide to pass in and out of cells.References:
