OBJECTIVES
• Students will be able to list the components of blood and their functions with 100% accuracy.
• Students will be able to create a blood mixture illustrating the components based on the make up of blood

IMPORTANCE
• Transports oxygen and nutrients to the lungs and tissues
• Forms blood clots to prevent excess blood loss
• Carries cells and antibodies that fight infection
• Brings waste products to the kidneys and liver (Kidney and Liver filter and clean blood)
• Regulates body temperature

What does blood run through?
Veins- Low pressure
Arteries- High pressure
Capillaries- Doorway between Veins and arteries
All: Tubes that carry oxygen-depleted blood toward the heart.

PLASMA• Thick liquid
• Transports food and waste
• Carries Proteins
• Regulates Bleeding and Clotting

RED BLOOD CELLSErythrocytes (RBC’s)
• Carries oxygen and carbon dioxide throughout the body
• Carries Nutrients

WHITE BLOOD CELLSLeukocytes
• Fight Infection
• Significantly larger than red blood cells
• Far fewer cells then red
• Clean up old blood cells
• Fight the germs that enter your body

PLATELETSThrombocytes
• Tiny cell fragments
• Form clots when cut
• Too Few Platelets: extensive bleeding• Too Many: leads to unnecessary clotting, stokes and heart attacks
