Lab #9 - The mammalian and avian blood

A specialized tissue in which new blood cells are formed.

• Hematopoietic tissue

• epithelial tissue

• connective tissue

Occurs within the spongy trabeculae of the bone adjacent to vascular sinuses.

• Hematopoietic tissue

• Hematopoiesis

What are the two major types of blood cells? (select 2)

• Granulocytes

• Agranulocytes

• Erythrocytes

• Leukocytes

Among the choices, which is not a granulocyte? (select 2)

• Lymphocytes

• neutrophils

• eosinophils

• basophils

• monocytes

These cells have prominent cytoplasmic granules that are lysosomes containing the enzymes released when neutrophils are recruited into inflammatory reactions.

• Neutrophils

• Band neutrophils

• Eosinophils

• Basophils

• Lymphocytes

These WBC have multilobed nuclei. It circulates for about 12 hours and, therefore, must constantly be replaced from the marrow.

• Neutrophils

• Band neutrophils

• Eosinophils

• Basophils

• Lymphocytes

A few of these slightly immature neutrophils circulate, and they have a crescent shaped nucleus that has not yet become lobated. They also have cytoplasmic granules.

• Band neutrophils

• Eosinophils

• Basophils

• Lymphocytes

• Monocytes

These specialized granulocytes are not numerous. They have prominent bright red cytoplasmic granules. They respond to allergic reactions and parasitic infections.

• Neutrophils

• Eosinophils

• Basophils

• Lymphocytes

• Monocytes

These granulocytic cells have prominent dark purple cytoplasmic inclusions. They are at least numerous of circulating white blood cells.

• Neutrophils

• Eosinophils

• Basophils

• Lymphocytes

• Monocytes

Both T and B cells circulate, with about 80% of the peripheral blood_ , being T cells. These cells have a single large nucleus and scant blue cytoplasm. These blood cells can live for months to years.

• Band neutrophils

• Eosinophils

• Basophils

• Lymphocytes

• Monocytes
