Level#1: Veins are blood vessels that carry blood toward the heart. Arteries are blood vessels that carry blood away from the heart. Capillaries are tiny blood vessels that connect arteries to veins.
1. What are the tiny blood vessels called that connect arteries to veins?
2. What is the job of the arteries?
3. In what direction do the veins carry blood?
Level#2: Veins are blood vessels that carry blood toward the heart. Arteries are blood vessels that carry blood away from the heart. Capillaries are tiny blood vessels that connect arteries to veins. Oxygen and nutrient molecules pass through the capillary membranes into body cells. At the same time, waste molecules from the body cells pass into the blood. These wastes are carried through veins back to the heart and into the lungs. You exhale some of the wastes into the air.
1. Where do waste molecules from body cells go?
2. Which blood vessels carry wastes back to the heart and into the lungs?
3. Where do the wastes that you exhale go?
Level#3: Veins are blood vessels that carry blood toward the heart. Arteries are blood vessels that carry blood away from the heart. Capillaries are tiny blood vessels that connect arteries to veins. Oxygen and nutrient molecules pass through the capillary membranes into body cells. At the same time, waste molecules from the body cells pass into the blood. These wastes are carried through veins back to the heart and into the lungs. You exhale some of the wastes into the air. Blood transports nutrients, oxygen, and wastes, and fights infection. About 55 percent of blood is a liquid called plasma. This liquid carries nutrients and wastes throughout the circulatory system.
1. Explain the job the blood does for the body.
2. Explain what plasma is and what percent of the blood it makes up.
3. What job does plasma do?
