The second least numerous WHC in peripheral circulation are the

Acidophilus

____________ are large phagocytic WBC that remain in circulation for only about 24 hours before entering peripheral tissues to become tissue macrophages

Monocytes

Agglutinogens of various blood types are example of

Surface antigens

the least numerous white blood cells in peripheral circulation are the

basophils

Formed elements that are nucleated and capable of amoeboid movement are

leukocytes

When foreign cells invade the body, one would most likely expect to see increased number of

lymphocytes

A normal WBC count is about _________ cells per microliter

5,000-10,000

the primary function of a white blood cell is to

help defend the body against pathogens

A sample of tissue from an injury shows a large number of eosinophils. This would indicate that the tissue was

infected by parasites

The most abundant type of WBC in a normal blood sample is

neutrophil

The pus associated with infected wounds contains which type of WBC

neutrophils

Which of the following are the most active type of leukocytes, phagocytically, and are usually the first to arrive at an injury cite

neutrophils

Type AB blood contains

Agglutinogen A and Agglutinogen B

Neutrophils

are active in fighting bacterial infection

Agglutinins

are antibodies that will attack surface antigens on RBCs of a different blood type

Which of the following is an agranulocyte

monocyte

The white blood cells that are important in leaving the blood vessels and phagocytizing large materials, releasing chemicals that draw fibroblasts to the injured areas are

monocytes

Which of the following leukocytes enter into the peripheral tissues and mature into tissue macrophages

monocytes

although technically they have granules, these cells were traditionally classified as "agranulocytes"

monocytes

A person's blood type is determined by the

presence or absence of specific surface antigens on the plasma membrane

Which of the following terms is related to the ability of white blood cells to leave blood vessels and crawl through connective tissues

Ameboid movement, diapedesis and extravasation

Bill wants to determine his blood type, so he takes a few drops of blood from a puncture wound in his finger and mixes it with various antisera. His blood cells agglutinate when mixed with the anti-A sera but not with the anti-B or anti-D sera. This means

Bill's plasma contains anti-B antibodies

____________ is the characteristic of WBC that allow them to enter surrounding tissue by squeezing between adjacent epithelial cells in the capillary wall

diapedesis
