Immune Cells Quiz

Study Notes

Neutrophils

Polymorphonuclear shape facilitates movement through tissue.
Key role in early immune responses.
Functions primarily in phagocytosis, engulfing pathogens and debris.

Lymphocytes

Comprises T cells, B cells, and Natural Killer (NK) cells.
Mononuclear shape aids in specific immune functions.
B cells are responsible for antibody production.
T cells facilitate cell-mediated immunity and activate B cells.
NK cells target and destroy infected cells through apoptosis.

Monocytes

Exhibits a pleomorphic shape for adaptability in response to various stimuli.
Functions in phagocytosis and contributing to the inflammatory response.
Differentiates into macrophages that play a significant role in immune defense.

Eosinophils

Possess a polymorphonuclear shape similar to neutrophils.
Function in inflammatory responses, especially in allergic reactions.
Assist in immunity and also engage in phagocytosis.

Basophils

Characterized by a polymorphonuclear shape.
Initiate immune and allergic reactions by releasing histamine and heparin from granules.
Play a lesser role in phagocytosis compared to other white blood cell types.

Erythrocytes

Commonly referred to as red blood cells.
Function primarily in the transport of oxygen and carbon dioxide in the blood.

Leukocytes

The general term for white blood cells.
Key players in the immune system, providing defense against infections and pathogens.

Thrombocytes

Also known as platelets.
Crucial for blood clotting and wound healing by aggregating at injury sites and releasing clotting factors.

Description
