Blood
Oxygen

Carbon dioxide
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.
Oxygen enters a person's bloodstream through the lungs. The blood carries oxygen to the cells of the body. In the cells, oxygen combines with chemicals obtained from food to produce the energy needed for each cell to perform its function in the body.
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.

They would bleed to death.
Nothing. Clotting is not important.
They would have to take special clotting drugs.
They would have to take regular doses of plasma.
You would bleed to death.
A scab will form on the skin surface.
Platelets stick to the edges of the cut and to one another, forming a plug.
The flow of blood to tissues beyond the clot may be cut off.
Platelets are exchanged for plasma.
Carbon dioxide is replaced with oxygen.
Blood fills the lungs and causes coughing.
Nothing -- the lungs are just a place blood goes through on its way back to the heart.
It starts to clot.
It gets old and dirty flowing through the body.
The oxygen in it is replaced with carbon dioxide.
The farther blood is from the heart, the more dark red it is.

Three: white cells, red cells, and plasma
Four: Types A, B, AB, and O
