Circulatory System What is the circulatory system? The body's breathing system The body's system of nerves The body's food-processing system The body's blood-transporting system From what source do cells get their food? Blood Oxygen Other cells Carbon dioxide Why is oxygen important to blood and to the cells? Oxygen helps the blood to clot. Oxygen brings food to the cells. Oxygen is necessary for cell growth and energy. Oxygen is not important-carbon dioxide is the most important substance to the body. Which type of blood vessels carries blood away from the heart? Veins Arteries Capillaries Arteries, veins and capillaries Why is blood that flows from the lungs to the heart bright red rather than dark red? Oxygen makes it red. Carbon dioxide makes it red. Gastric juices produce the red colour of the blood. The lungs add a pigment (dye) to blood as it flows through them. What part of the blood carries minerals, vitamins, sugar, and other foods to the body's cells? Plasma Stunning images of cells Platelets Red corpuscles White corpuscles What is the main job of the red corpuscles in the blood? To clot blood To fight disease To transport oxygen to the body's cells and carry away carbon dioxide from the cells To transport carbon dioxide to the body's cells and carry away oxygen from the cells
