Front 20

What are the 7 characteristics of Erythocytes?

Back 20

-Transports CO2 and O2

-Disc shaped for greater surface area

-Plasma membrane has antigens (glycocalyx)

-Life-span of 3-4months

-Devoid of most organelles-no mitochondria (can’t use up the O2)

-Carbonic anhydrase (CAH) CO2 + H2O ↔ H2 CO3 ↔ HCO3- + H+

-Hemoglobin (15g/100mL) carriers O2 (in cytoplasm)

Front 21

What are 4 characteristics of Erythocyte hemoglobin?

Back 21

- 4 protein chains

- Heme molecule with iron→ binds O2

- HbA- adult

- HbF- fetal binds O2 more tightly

Front 22

Type of Leukocyte: What is a Granulocyte?

Back 22

a white blood cell with secretory granules in its cytoplasm, e.g., an eosinophil or a basophil.

Front 23

5 Characteristics of Neutrophils?

Back 23

- 50-70% of WBCs

- 3-5 lobes, cytoplasm stains a pale lilac color with fine granules

- Bacterial infections

- Phagocytosis-release antimicrobial chemicals (lysosomes, defensins)-respiratory burst.

- Sometimes referred to as stab cells-band cells or polymorphonuclear cells (PMN).

Front 24

3 Characteristics of Eosinophil?

Back 24

- 2-4%, 2 large lobes-cytoplasm stains a red-orange color with large granules

- Parasitic infections (worms)-allergic reactions

- Phagocytosis-release enzymes to digest the pathogen-destroy antigen-antibody complex and inhibit the effects of inflammation usually associated with allergic reactions.

Front 25

4 Characteristics of Basophil?

Back 25

- .5-1%
- Cytoplasmstains a deep bluish-purple color with abundant granules
- Chicken pox-diabetes-polycythemia
- Secrete histamine & heparin → increase blood flow & mobility of WBCs to the infected area.

Front 26

What are Agranulocyte?

Back 26

Also known as mononuclear leukocytes, are white blood cells with a one-lobed nucleus. They are characterized by the absence of granules in their cytoplasm, which distinguishes them from granulocytes
