A&P Exam-Focused Study Guide: WBCs & Plasma Proteins

A set of vocabulary flashcards covering key concepts related to white blood cells (WBCs) and plasma proteins, focusing on definitions and functions.

Agranulocytes

White blood cells that include Monocytes and Lymphocytes.

Granulocytes

White blood cells that include Neutrophils, Eosinophils, and Basophils.

Neutrophils

Most abundant white blood cells, first responders to infection, with a multi-lobed nucleus.

Monocytes

Largest white blood cells that arrive after neutrophils and can differentiate into macrophages or dendritic cells.

Lymphocytes

Agranulocytes involved in adaptive immunity, including B cells, T cells, and NK cells.

Order of Immune Response

Neutrophils first, followed by monocytes (macrophages), then lymphocytes.

Neutrophils vs Monocytes

Neutrophils are granulocytes with a fast response and short lifespan; Monocytes are agranulocytes with a slower response and long lifespan.

Albumins

Most abundant plasma protein that maintains osmotic pressure and transports hormones, drugs, and fatty acids.

Globulins

Plasma proteins involved in immune defense and transport.

Fibrinogen

A plasma protein essential for blood clotting, converted to fibrin during clot formation.
