13. Cornell Notes Topic/Title: Blood Components

14. Blood The only fluid tissue in the human body Classified as a connective tissue

15. Blood Figure 10.1

16. Components of Blood PLASMA (55%) WHITE BLOOD CELLS & PLATELETS (>1%) RED BLOOD CELLS (45%)

17. Components of Blood FORMED ELEMENTS (Red & White Blood Cells and Platelets)

18. Blood Plasma ~ 90% water Liquid part of blood – Nutrients – Hormones – Proteins

19. Formed Elements Erythrocytes = red blood cells Leukocytes = white blood cells Platelets = clotting cells

20. Photomicrograph of a Blood Smear Figure 10.2

21. Erythrocytes (Red Blood Cells) Main function = carry oxygen Hematocrit = percentage of red blood cells in our body

22. Anemia Someone is anemic if they have: – A lower than normal amount of red blood cells or – Not enough hemoglobin Sickle-cell anemia – Common in African Americans – Sharp and spiky RBC  low oxygen Above: Normal RBC Below: Sickled RBC

23. Control of Erythrocyte Production Figure 10.5

24. White blood cells and platelets: Make up less than 1% of the formed elements White blood cells (leukocytes) = fight infections Platelets = involved with blood clotting and wound repair

25. Summary Summarize what we learned today about blood!
