Gylys Chapter 9 Anatomy and Physiology

What is a/an antibody?

• A substance, recognized as harmful, that stimulates formation of cytokines in an immunocompetent individual

• A protective protein produced by B lymphocytes in response to a foreign substance called an antigen

• A chemical substance produced by certain cells that initiates, inhibits, increases, or decreases activity in other cells

• A specialized type of monocyte that displays antigens on its cell surface and presents them to components of the immune system

The development of blood cells into their mature forms is called

• hemostasis

• homeostasis

• hemopoiesis

• hemosiderin

RBCs live about 120 days and then breakdown, releasing hemoglobin which releases an iron compound called

• blasts

• dendritic cells

• bile pigments

• hemosiderin

Which embryonic cells migrate to the lymphatic system to complete their maturation and development?

• monocytes and lymphocytes

• lymphocytes and erythrocytes

• monocytes and basophils

• neutrophils and monocytes

The migration of WBCs though the endothelial walls of capillaries and venules is called

• phagocytosis

• diapedesis

• hemosiderin

• hemopoiesis

Which three leukocytes have multiple nuclei and have granules in their cytoplasm

• neutrophils, lymphocytes, basophils

• monocytes, lymphocytes, neutrophils

• neutrophils, eosinophils, basophils

• eosinophils, lymphocytes, basophils

Which is the correct order of the process of hemostasis

• injury to vessel, thromboplastin released, platelets aggregate, fibrinogen becomes insoluble, fibrin forms to trap blood cells

• injury to vessel wall, platelets aggregate, thromboplastin released, fibrinogen becomes insoluble, fibrin forms to trap blood cells

• injury to vessel, fibrin forms to trap blood cells, fibrinogen becomes insoluble, thromboplastin released, platelets aggregate

• injury to vessel, fibrinogen becomes insoluble, platelets aggregate, thromboplastin released, fibrin forms to trap blood cells

What is blood serum

• the liquid portion of the blood in which blood cells are suspended

• the thin almost colorless fluid that is composed of 92% water as well as albumins, globulins, fibrinogen, clotting factors, gases, nutrients, salts, and hormones

• formed elements which make up 45% of whole blood

• a product of blood plasma formed when fibrinogens and clotting factors are removed from blood plasma

Human blood is divided into 4 groups, A, B, AB, O, based on the presence of what on the surface of the RBCs

• antibodies

• antigens

• proteins

• erythrocytes

What is lymph made up of

• lymphocytes, neutrophils

• lymphocytes, basophils

• lymphocytes, monocytes

• lymphocytes, eosinophils
