Neutrophil function

First ones to infection site and breaks down and kills bacteria, viruses, etc.

Eosinophil function

Uses exocytosis to release toxins onto surface of large parasite.

Basophil function

[Histamine] Increases permeability of capillaries and [Heparin] reduces blood clotting.

Monocyte function

Leave vessel and become macrophages.

Lymphocyte function

Migrates from blood to tissue through lymph and returns to blood.

White blood cells that phagocytize

Neutrophils, Eosinophils, Monocytes

White blood cells that do not phagocytize

Basophils and Lymphocytes

Neutrophils release

Toxins to kill bacteria and chemicals to call white blood cells to site

Eosinophils release

Chemicals that cause allergic reactions

Basophils release

Granules of Histamine and Heparin

Monocytes release

Chemical messengers

Lymphocytes release

Nothing

Leukocytes (WBCs) that are granulocytes/stain dark

Neutrophils, Eosinophils, and Basophils

Leukocytes (WBCs) that are agranulocytes

Monocytes and Lymphocytes

3 general properties of leukocytes

Defend, have nuclei, and is made in lymphatic tissue (such as bone marrow)

Location of most leukocytes

Bone marrow, Thymus, Spleen, mostly in tissues or organs of the Lymphatic System.

General characteristics of WBCs

Move along capillaries by amoeboid movement, detect injured cells, leave the capillary by squeezing through cells-diapedesis, positively chemotactic in the tissue, and finally, can destroy things by phagocytosis.

List WBCs in order of abundance

Neutrophils (54-62%), Lymphocytes (25-33%), Monocytes (2-8%), Eosinophils (3%), and Basophils (<1%)
