2
Plasma

• 90 Water with 100
• different dissolved
• solutes 8 plasma proteins
• 60 albumin-carrier for
• certain molecules , buffer, major in contributing
  to osmotic
• pressure alone with Na

3
Red blood cell

• Origin- bone marrow
• Function- gas transport (1 billion O2 each)
  produce ATP anaerobically hemoglobin

• Hemoglobin
• substance containing iron found in red blood
  cells, which helps the blood to exchange carbon
  dioxide for oxygen.

4
Neutrophil

• Origin- bone marrow
• Function- most numerous
• numbers with bacterial
• infections phagocytize
• bacteria and some
• fungi contain defensins

5
Eosinophil

• Origin- bone marrow
• Function- kill parasitic worms destroy
  antigen-antibody complexes inactivate some
  inflammatory chemicals or allergies.

6
Basophil

• Origin- bone marrow
• Function- rarest release histamine and other
  mediators of inflammation contain heparin, an
  anticoagulant, that acts as a vasodilator.

7
Lymphocyte

• Origin- bone marrow, lymph nodes, spleen.
• Function- mount immune response by direct cell
  attack or via antibodies.

8
Monocyte

• Origin- bone marrow
• Function- during chronic infections
  phagocytosis develop into macrophages in
  tissues attack viruses and certain intracellular
  bacterial parasites.

9
Platelet

• Origin- bone marrow
• Function- critical role in blood clotting
• Smallest cell in the blood.
• When a blood vessel is cut, platelets clump
  together to plug it.

10
ABO Blood Groups

• Four basic groups A, B, AB, O.
• Discovered by Karl Landsteiner 1900
• Based on 2 Antigens (A and B)

11
AnemiaInsufficient number of rbcs

• Anemia is not a disease.
• There are a decreasing number of red blood cells,
  which carry oxygen, thus less oxygen.
• If you are tired you may suspect anemia.

• Signs
• light headedness
• pallor (pale skin)
• weakness, tiredness, fatigue
• chest pains
• headaches
• etc..

12
AnemiaDecreases in hemoglobin content

• Hemoglobin is the red pigment in red blood cells
  that carry oxygen to different parts of the body.
  
• A decrease in hemoglobin equals a decrease in
  oxygen circulation.

13
AnemiaAbnormal hemoglobin

• Sickle cell anemia is abnormal hemoglobin.
• It is a hereditary disorder that primarily
  affects people of African ancestry.
• It occurs when two abnormal cells are inherited.
• Instead of being flexible and round, these cells
  are rigid and curved.

14
WBC disorder- Leukemia

• It occurs when there is a large number of
  abnormal white blood cells .
• They are called leukocytes.
• Since these cells are abnormal they dont help
  protect your body against infection.

15
WBC disorder- mononucleosis

• It is caused by the Epstein-Barr virus.
• A member of the herpes family.
• Once youve been infected it stays in your body
  for the rest of your life, and can reappear in
  saliva.
