2. Neutrophil
-Carried by blood flow
Function: to protect the cell from pyogenic
bacteria and aide in destroying and separating
damaged tissue from other parts of the cell (by
participating in the inflammatory process)

3. Lymphocyte
-Regulates the immune system, effects cellular immunity and
produces antibodies to fight off disease.
-Four Different types: B-cells-produce most of the antibodies to
destroy foreign cells, such as bacteria, killer T-cells, helper T-cells,
inflammatory T-cells (T-cells produce cytokines which control
immune responses)

4. Monocyte
-Replenish certain immunity cells to their normal state and can
move quickly to an infected area and help with immunity and
kill the bacteria in that area by dividing and multiplying

5. Eosinophil
-Produced at a low level in the blood stream
-Normally function to try to protect the body by killing
bacteria and parasites. They also can cultivate in the
bowels, when large parasites are present (and try to
engulf this parasite), instead of doing this inside the body.
-Also, when they attack bacteria and other
microorganisms, they can cause serious damage to
other normal cells.

6. Basophil
-Can produce biologically active cells, such as
histamine. Basophil function is not completely
understood, but they relate to allergies and are
associated with ingesting foreign particles.

7. Platelets/Erythrocytes fraction of the
• Platelets are so small, they make up just a tiny
blood volume. The principal function of platelets is to
prevent bleeding. They are circulating fragments of cells.
• Erythrocytes contain hemoglobin and carry oxygen to the
body. They are biconcave in shape. They are also very
flexible and change shape when flowing through the
capillaries.

8. Malaria
-Malaria is caused by a parasite that is passed from one
human to another by the bite of infected Anopheles
mosquitoes. After infection, the parasites travel through the
bloodstream to the liver, where they mature and release
another form, the merozoites. The parasites enter the
bloodstream and infect red blood cells. The parasites
multiply inside the red blood cells.
-The effect of
malaria causes a
mutation in normal
blood cells. They
become
rigid, brittle, deform
ed, and begin to
have drastic
skeletal
malfunctions.

9. Blood Cells
1. Red blood cells are also called erythrocytes.
2. The shape of a red blood cell can be described as a
biconcave disk.
3. The shape of a red blood cell is related to its function
of transporting gases.
4. Hemoglobin is the oxygen-carrying substance in a red
blood cell.
5. Red blood cells with high oxygen concentrations are
bright red because of the presence of oxygen.
6. Red blood cells cannot reproduce because they lack
nuclei when they mature.
7. White blood cells are also called leukocytes.
8. White blood cells with granular cytoplasm are called
granulocytes.
9. White blood cells lacking granular cytoplasm are
called agranulocytes.
10. 10. Polymorphonuclear leukocyte is another name for a
neutrophil with a segmented nucleus.
11. Normally, the most numerous white blood cells are
neutrophils.
12. White blood cells whose cytoplasmic granules stain
red in acid stain eosinophils.
13. Basophils are normally the least abundant of the
blood cells.
14. Monocytes are the largest of the white blood cells.
15. Lymphocytes are small agranulocytes that have
relatively large, round nuclei with thin rims of
cytoplasm.
16. IN red bone marrow, platelets develop from cells
called megakaryocytes.
17. Upon an injury, platelets adhere to broken surfaces
found in connective tissue.
18. In the presence of damaged blood vessels, platelets
release a substance called serotonin that causes
smooth muscle contraction.
