2. B ELL W ORK What blood type… is the Universal DONOR? O-, no antigens is the Universal RECIPIENT? AB+, all antigens, no blood antibodies What blood type are Jeff, Steven and Mark? J  A+, S  B-, M  O+ Can Jeff donate blood to Steven? No, Steven does not have A or Rh antigens Can Mark donate blood to Steven? No, positive to a negative Can Mark donate to Jeff? Yes, nothing foreign in his blood (Jeff already has the Rh factor.) Anti AAnti B Rh JeffStevenMark

3. CARDIOVASCULAR SYSTEM The Heart

4. H EART ( THE PUMP ) 1 organ 2 functions, 2 sides, 2 pumps 1) Pumps venous blood to the lungs 2) Pumps arterial blood to the cells

5. H EART S TRUCTURE 4 Chambers LEFT VENTRICLE RIGHT VENTRICLE RIGHT ATRIUM LEFT ATRIUM

6. CARDIOVASCULAR SYSTEM

7. Blood is circulated by the heart and blood vessels. In one day, blood will be circulated 1 400 times!

8. CARDIOVASCULAR SYSTEM Includes Blood Blood vessels Heart

9. DIAGRAMS Vessels carrying O2 rich blood are RED Vessels carrying CO2 rich blood are BLUE

10. BLOOD VESSELS Different types, based on size and where they are going

11. BLOOD VESSELS Arteries and Arteriols Small blood vessels carrying arterial (O 2 rich) blood away from the heart to give O 2 to the cells. *except pulmonary artery

12. BLOOD VESSELS Arteries and Arteriols Small blood vessels carrying arterial (O 2 rich) blood away from the heart to give O 2 to the cells. Larger arteries subdivide into smaller arterioles. Has a lot of power because blood just left the heart.

13. BLOOD VESSELS Arteries and Arteriols Thick walls to resist high pressure

14. BLOOD VESSELS Capillaries Thinnest blood vessels Allow diffusion through a semi-permeable membrane

15. BLOOD VESSELS Capillaries Blood cells travel through in single file Walls are a single layer of cells Diffusion of gases and nutrients

16. BLOOD VESSELS Veins and Venules Small blood vessels that carry blood back to the heart. (CO 2 rich except pulmonary vein) Many smaller venules lead to larger veins

17. BLOOD VESSELS Veins and Venules Veins have valves to keep blood from flowing downward Blood has lost power from the heart Blood is fighting gravity

18. BLOOD VESSELS Veins and Venules Veins have valves to keep blood from flowing downward Blood has lost power from the heart Blood is fighting gravity Valves open and close, creating suction.

19. MAJOR BLOOD VESSELS Connected to the heart Aorta  Largest artery of the body  Carries arterial blood

20. MAJOR BLOOD VESSELS Connected to the heart Pulmonary Vein Carries ARTERIAL (O 2 rich) blood from lung to heart

21. MAJOR BLOOD VESSELS Connected to the heart Pulmonary Artery Carries VENOUS blood (CO 2 rich) from the heart to the lungs

22. MAJOR BLOOD VESSELS Connected to the heart Inferior Vena Cava Carries venous blood from lower veins to the heart

23. MAJOR BLOOD VESSELS Connected to the heart Superior Vena Cava Carries venous blood from upper veins to heart
