Front 22

How many oxygen molecules can a single hemoglobin molecule carry?

Back 22

4.

Front 23

Why can a hemoglobin molecule carry only 4 oxygen molecules?

Back 23

Because the oxygen binds to the heme group and each hemoglobin molecule only has 4 heme groups.

They are cytoplasic fragments of megackaryocytes.

Front 28

Megakaryocyte

Back 28

A cell in red bone marrow.

What is the function of thrombocytes?

Back 29

The stoppage of blood flow; blood clotting.

Back 30

Hemocytoblast, megakaryocyte, platelets.

Front 35

Neutrophil

Back 35

50-70%, 10-12 micromiters, basophilic, banded or 2-6 lobes, eosin & methylene blue eye, functions in phagocytosis and exocytosis, granulocyte, microphage, polymorphonuclear leukocyte.

Front 36

Basophil

Back 36

0.5-1%, 10-14 micrometers, basophilic, usually biloped, methylene blue dye, causes inflammation and allergies, granulocyte, similar to mast cells in tissues.

Front 37

Eosinophil

Back 37

2-5%, 10-14 micrometers, basophillic, usually bilobed, eosin dye, functions in destroying parastic worms and stopping inflammation, granulocyte, works hand in hand with basophils.

Front 38

Monocyte

Back 38

3-8%, 14-24 micrometers, basophilic, often folded or indented, functions in phagocytosis (cell eating), agranulocyte, becomes a macrophage in tissues.

Front 39

Lymphocyte

Back 39

25-45%, 5-17 micrometers, basophilic, clumped cromatin, functions in immune response, agranulocyte, has 3 main types (B cells, T cells, and NK cells).
