1. BLOOD Ms. Whitney | Vet Science | Block 4 | Kiel High School

2. 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

3. 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

4. ~55% ~44%

5. 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.

6. VIDEO Why is Blood Important? What to Look For Component Functions/ Purpose

7. BLOOD COMPONENTS

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

9. RED BLOOD CELLS Erythrocytes (RBC’s) Carries oxygen and carbon dioxide throughout the body Carries Nutrients

10. WHITE BLOOD CELLS Leukocytes 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

11. PLATELETS Thrombocytes Tiny cell fragments Form clots when cut Too Few Platelets: extensive bleeding Too Many: leads to unnecessary clotting, stokes and heart attacks
