Types of Blood CellsBy: Jenna Martin Danielle David Victoria Snoddy

Neutrophil-Carried by blood flowFunction: 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)

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)

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

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.

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.

Platelets/Erythrocytes• Platelets are so small, they make up just a tiny fraction of

the 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.

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, deformed, and begin to have drastic skeletal malfunctions.

Blood Cells1. 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. 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.
