3. Why is blood so important to survival?

4. Functions of Blood
transport medium
protection (immunity)
regulation

6. What is blood made of?

7. What are the four main parts of blood?
Red blood cells
White blood cells
Platelets
Plasma

8. (as a cell, tissue, organ, or organ system?)
How would blood be classified?
(as a cell, tissue, organ, or organ system?)

9. blood -
a fluid tissue composed of plasma in which RBC's, WBC's, and platelets are suspended

10. Red Blood Cells

11. There are 5,000,000 red blood cells in one drop (1 microliter) of blood
There are about 5 liters of blood in the body.
How many red blood cells are there in the body?

12. There are 25,000,000,000,000 red blood cells in the human body.
If 3 million red blood cells die each second, then how many must be made to replace them in one day?
259,200,000,000

13. Development of Red Blood cells

14. Bone Marrow

15. Why do red blood cells have this shape?

16. Side view of a red blood cell
oxygen
carbon dioxide
(blood vessel in lungs)

17. Side view of a red blood cell
oxygen
carbon dioxide
(blood vessel in tissues)

19. How is a red blood cell like a taxi?
oxygen
Tissues
Lungs
Carbon dioxide

20. 1 2 1 - Oxygen, nutrients, hormones CELLS IN BODY BLOOD
1 – metabolic wastes including Carbon dioxide, hormones

21. red blood cell

24. Hemoglobin

25. Hemoglobin
a complex iron-containing protein that carries oxygen and carbon dioxide throughout the body and gives blood its red color

26. Sickled Cell

28. Anemia
Decreased ability of the red blood cells to provide adequate oxygen supplies to body tissues.

29. Sickle-cell anemia:
an inherited, potentially lethal disease in which a defect in hemoglobin, the oxygen-carrying pigment in the blood, causes distortion (sickling) and loss of red blood cells, producing damage to organs throughout the body.

30. Causes of Anemia abnormal hemoglobin insufficient amount of hemoglobin
insufficient amount of red blood cells
Causes - dietary deficiency
- premature destruction of red blood cells

31. White Blood Cells

34. Immune Cells

35. White Blood Cells
protect the body from pathogens

44. What is this?

45. How do blood clots form?

46. Clotting Animation http://health.howstuffworks.com/adam-200077.htm

47. Platelets

48. Platelets
Adhere (attach) to the walls of broken blood vessels (sealant)
Adhere to each other to help establish a clot
Release chemicals which stimulate the blood to clot

51. A Blood Clot Forming 1
platelet 2
fibrin 3
Red blood cell

52. The Process of Blood Clotting
Blood vessel injured
Platelets release Thromboplastin
Prothrombin Thrombin
Fibrinogen Fibrin
Fibrin Net traps Platelets and Red Blood cell to form clot

54. The Process of Blood Clotting
When a blood vessel is injured, platelets in the blood release a protein (fibrin) that forms a net
This net traps blood cells and platelets forming a blood clot

55. Coronary Thrombosis

56. How are blood clots dissolved?

58. What do these creatures have in common?

59. substances that prevent clot formation
anticoagulants
substances that prevent clot formation
- heparin - used as a drug after surgery to prevent clotting
