Lymphocytes are specialized leukocytes. Lymphocytes include T cells, B cells, and natural killer (NK) cells.

Which of the following is considered a type of lymphocyte?

Identifying Leukocytes

to mount immune response by direct cell attack or via antibodies

to release histamine and other mediators of inflammation

Which of the following is a function of neutrophils?

Although arising from different cell lines, granulated mast cells are similar to basophils.

Mast cells are most similar to which type of leukocyte?

Eosinophils kill parasitic worms and play a role in the body’s response to allergens and asthma.

Which of the following types of white blood cells kills parasitic worms and plays a role in the body's response to allergens and asthma?

Chemotaxis is the process by which leukocytes follow the trail of chemicals released by injured cells at the site of inflammation.

Diapedesis is the ability of certain cells to slip out of the capillary blood vessels.

Amoeboid movement is the movement produced by the extension of the cytoplasm as pseudopodia move into the environment.

The process of actively metabolizing oxygen by neutrophils to produce bleach and hydrogen to kill bacteria is known as __________.

The Composition and Function of Blood

WBCs are nucleated and have a protective function.

WBCs retain their nuclei and help protect the body against foreign invaders.

Which property do white blood cells (WBCs) have in common?

Lymphocytes are specific immune system cells that destroy the body's invaders.

Which of the following is a function of lymphocytes?

the engulfing of foreign bodies by leukocytes

To protect the body from foreign invasion, WBCs need to leave circulation and move out of capillary vessels into tissue space, a process called diapedesis.

the type of movement erythrocytes use in the tissue spaces

the movement of leukocytes from blood vessels into tissue spaces

the chemical attraction leukocytes use to reach the site of tissue damage

the secretion of chemicals that trigger the inflammatory process

The granules in basophils contain histamine.

Which leukocytes contain histamine in their granules?

How are White Blood Cells made? Leukopoiesis Regulation

Structure and Function of White Blood Cells - Leukocytes 

The migration of white blood cells out of the blood vessels is called diapedesis. Leukocytosis is an increase in leukocyte count. Transcytosis is the movement of a substance across a cell layer. Active transport is a means of moving a substance into or out of a cell against a concentration gradient.

The migration of white blood cells out of the capillary blood vessels is called __________.
