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 blood vessels called that carry blood away from the heart?





2. What are the blood vessels called that carry blood toward the heart?





3. What are capillaries and what do they do?





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 into the lungs. Your exhale some of the wastes into the air.

1. What do the veins and arteries do with the blood?






2. What job do capillaries do as part of our circulatory system?






3. What two types of molecules pass through the capillary membranes and where do they 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 into the lungs. Your 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 function of; veins, arteries, and capillaries.







2. Explain what goes on in the capillaries.






3. Where do the wastes in the blood go and how are they gotten rid of?
