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.
A scab will form on the skin surface.
You would bleed to death.
They carry blood to all parts of the body.
They carry messages from the brain to the muscles.
They pump blood to the heart
They filter impurities from the blood.
Four: Types A, B, AB, and O
One: Type "O"
Three: white cells, red cells, and plasma
Two: white cells and red cells
The blood vessels and capillaries
The farther blood is from the heart, the more dark red it is.
It starts to clot.
It gets old and dirty flowing through the body
The oxygen in it is replaced with carbon dioxide.
Blood fills the lungs and causes coughing.
Nothing -- the lungs are just a place blood goes through on its way back to the heart.
Carbon dioxide is replaced with oxygen.
Platelets are exchanged for plasma.
Oxygen helps the blood to clot.
Oxygen is necessary for cell growth and energy.
Oxygen is not important -- carbon dioxide is the most important substance to the body.
Oxygen brings food to the cells.
The body's food-processing system
The body's system of nerves
The body's blood-transporting system
The body's breathing system
Arteries, veins and capillaries
Gastric juices produce the red colour of the blood.
Oxygen makes it red.
The lungs add a pigment (dye) to blood as it flows through them.
Carbon dioxide makes it red.
to clot blood
To transport carbon dioxide to the body's cells and carry away oxygen from the cells
to fight illness
To transport oxygen to the body's cells and carry away carbon dioxide from the cells
white blood cells
red blood cells
They would have to take regular doses of platelets.
They may bleed to death.
They would have to take regular doses of plasma.
Nothing. Clotting is not important.
