1. Allergen- Antigen capable of causing a hypersensitivity or allergy in the body.
2. Antibody- Protein material produced in body as a response to invasion of foreign substance.
3. B cells- (also called B lymphocytes) cells produced by the immune response process, humoral immunity. These cells respond to antigens by producing protective protein antibodies.
4. Bilirubin- Waste portion of damaged red blood cells that are disposed of by the liver.
5. B lymphocytes- (also called B cells) cells produced by the immune response process, humoral immunity. These cells respond to antigens by producing protective protein antibodies.
6. Cell-mediated immunity- (also called cellular immunity) process results in production of T cells and natural killer cells that directly attach to foreign cells, immune response fights invasion by viruses, bacteria, fungi, and cancer.
7. Eosinophils- a type of granulocyte white blood cells (those w/ granules in the cytoplasm) that destroy parasites and increases during allergic reactions.
8. Erythrocytes- red blood cells containing hemoglobin that bind w/ oxygen from the lungs and deliver it to the tissues of the body.
9. Erythropoiesis- (also called hematopoiesis) red blood cell production that occurs in bone marrow and involves maturation of nucleated precursors into erythrocytes regulated by the hormone erythropoietin produced in the kidneys.
10. Gamma globulin- a plasma protein that acts as an antibiotic to resist infection.
11. Granulocyte- subgroup of Leukocytes (white blood cells) that have granules in their cytoplasm
12. Hemoglobin- iron-containing pigment in red bloods cells that carries oxygen from the lungs to the tissue.
13. Immunoglobulins- antibodies secreted by the B cells. All antibodies are immunoglobulins and assist in protecting the body and its surfaces from the invasion of bacteria. For example, the immunoglobulin IgA in colostrum, the first milk from mother, helps to protect the newborn from infection.
14. Leukocytes- (white blood cells) that provide protection against pathogens, such as bacteria, viruses and other foreign material. Spherical in shape with a large nucleus, there are 5 types that are either granulocytes or agranulocytes.
15. Lymph nodes- small organs in the lymphatic system that filter bacteria and other foreign organisms from body fluids.
16. Macrophage- leukocytes present throughout all body tissues, but are concentrated in areas of high exposure to of bacteria invasion (lungs, digestive system, & lymph nodes), they are very active phagocytic cells ingesting and digesting any pathogen, they meet.
17. Monocytes- granulocyte type of white blood cells; they engulf foreign and damaged cells (phagocytosis)
18. Neutrophils- granulocyte type of white blood cells that are important for phagocytosis; also the most numerous leukocytes.
19. Passive acquired immunity- immunity that results when a person receives protective substances produced by another human or animal; may…
