Level#1: There are three kinds of solids in blood: platelets, red blood cells, and white blood cells. Platelets are actually pieces of cells. They help blood cells to clump together. This action helps wounds to stop bleeding. Red blood cells deliver oxygen to other body cells. White blood cells fight infection.

1. How many kinds of solids are in blood and what are they?





2. What are platelets and what do they help blood cells to do?





3. What do red blood cells do and what do white blood cells do?

Level#3: There are three kinds of solids in blood: platelets, red blood cells, and white blood cells. Platelets are actually pieces of cells. They help blood cells to clump together. This action helps wounds to stop bleeding. Red blood cells deliver oxygen to other body cells. White blood cells fight infection. A protein in red blood cells delivers oxygen to other body cells. This protein, called hemoglobin, contains the mineral iron. Iron gives the blood cells their red color. The more oxygen the protein carries, the brighter the color of the cells. White blood cells fight infection. They destroy harmful bacteria and defend the body against other harmful substances. You have fewer white blood cells than red blood cells. But, when your body is fighting an infection, the number of white blood cells can quickly increase.
