Q

Lymphocytes

A

Agranulocyte; involved with immune system. Smallest leukocyte. 4 kinds of leukocytes: T-cells, B-Cells, plasma cells, NK (natural killer) cells

17
Q

Monocytes

A

Agranulocytes; “second responder”, active immune response via phagocytosis. More common in chronic conditions

18
Q

Eosinophils

A

Granulocyte, stains red/pink; anti-inflammatory response, assists with immune system

19
Q

Basophils

A

Granulocyte, stains blue; contain histamine and heparin (for allergic response and anticoagulation). Rarest and least understood blood cell.

20
Q

Hemoglobin

A

A proteins found in red blood cells. Gives it its red color. Iron in it binds to oxygen, also carries carbon dioxide and protons.

21
Q

Petechiae
