  1. The functions of blood
    • Transportation
    • Regulation
    • Protection
  2. Transportation
    • O2/CO2
    • Nutrients
    • Heat and waste transport
  3. Regulation
    Homeostasis - temperature
  4. Protection
    • Clots
    • WBC
  5. Total blood volume for men
    5-6 liters
  6. Total blood volume females
    4-5 liters
  7. Ph of blood
    7.35-7.45
  8. Plasma
    55 percent of blood volume
  9. Components of blood
    • Total blood volume
    • ph
    • Plasma
    • White blood cells
    • Platelets
    • Red blood cells
  10. Red blood cells are also called
    Erythrocytes
  11. RBC production requires
    • Iron
    • vitamin B12
    • Folic acid
  12. Structure of red blood cells
    • No nucleus
    • Biconcave
    • Contains hemoglobin
  13. Function of red blood cells
    • Transport oxygen to and from the lungs
    • Regulates blood flow and blood pressure
    • RBC live 120 days
  14. Hemopoiesis
    • Process by which formed elements of blood develop
    • Primary site- red bone marrow
    • Epiphysis long bones
    • Flat bone
  15. Erythropoiesis
    • RBC formation
    • Erythropoietin- hormone produced by kidney controls RBC production
    • Lack of O2 to kidney increases # of RBC produced
  16. Oxyhemoglobin
    • Bright red blood
    • O2 bound to hemoglobin
    • Arterial blood
  17. Deoxyhemoglobin
    • Dark red blood
    • O2 poor
    • Venous blood
  18. Plasma
    • Watery strawberry colored liquid
    • Free of formed elements of blood
    • 91 percent water, rest primarily protein solutes
    • Function to maintain osmotic pressure
    • Solutes include
    • Nutrients, Hormones,Electrolytes
  19. White blood cells have two groups and contain a nucleus
    • Granular leukocytes- necessary form immunity to specific disease
    • Agranular leukocytes
  20. WBC Production
    • Red bone marrow
    • Lymph nodes
  21. Granular leukocytes are
    Eosinophils,Basophils, Neutrophils
  22. Agranular Leukocytes
    Lymphocytes, monocytes
  23. Function of WBC
    • Combat inflammation and infection -Neutrophils, macrophages
    • Histamine in allergic reaction- Eosinophils
    • Antibodies-B lymphocytes
    • Destroy foreign invaders-T lymphocytes
    • Bacteria and virus defense- Leukocytes
    • Immunity- B and T cells
  24. Plateslets (thrombocytes)
    • 150,00-400,00 per microliter of blood
    • Function to stop blood loss by forming platelet plug
    • Life span5-9 days
    • Removed by spleen and liver
  25. Hemostasis
    • Sequence of responses that stop bleeding
    • 3 mechanisms
    • Vascular spasm
    • Platelet plug
    • Blood clotting
  26. Vascular spasm
    • Arteries damaged walls contract,reduces
    • blood loss
  27. Platelet plug
    Aggregation of platelets stick to damaged area preventing blood loss
  28. Blood clotting
    Network of fibers formed elemments get trapped
  29. Blood types
    • A,B,AB and O and Rh designations
    • Based on the presence or absence of antigens
    • O positive is most common blood type in canada
  30. Three basic functions of blood
    • Transportation
    • Regulation
    • Protection
  31. Erythropoiesis defines
    Process of RBC formation
  32. Name hormones that controls erythropoiesis
    and state which organ secretes this hormone
    • Erythropoietin
    • Kidney
  33. List two types of WBC and sub types
    Granular Leukocytes - eosinophils, basophils,neutrphils

    Agranular Leukocytes- lymphocytes, monocytes
  34. What is the general function of WBC's list two
    • Combat inflamation and infection
    • Produce antibodies
  35. Describe the function of platelets
    Blood clotting
  36. Define hemostasis
    Stoppage of bleeding
