BMS 110 Exam 4 questions well
answered graded A+
sebum - correct answer ✔✔oil; protective substance
pathogens - correct answer ✔✔disease causing agents (bacteria, viruses, etc.)
Innate (nonspecific) immunity - correct answer ✔✔Inborn; same defenses regardless of
pathogen type
Acquired (specific) immunity - correct answer ✔✔develops over course of life. A specific attack
against a specific pathogen
First line of defense - correct answer ✔✔physical (integumentary system, mucus, hairs, etc.)
and chemical (sebum, gastric acid, normal bacteria flora lysoszyme) surface barriers
second line of defense - correct answer ✔✔Fever, inflammation, phagocytes
Third line of defense (specific) - correct answer ✔✔immune responses (T and B lymphocytes,
antibodies, and macrophages)
protects against a specific pathogen
Dependent of B and T cells (lymphocytes)
Does immune system identify whole pathogens or surface antigens? - correct answer
✔✔surface antigens
, lymphocytes - correct answer ✔✔B and T cells
Antigens - correct answer ✔✔proteins, lipids, oligosaccharides
T/F: Anything that is not recognized as self will be killed. - correct answer ✔✔True
Lymphatic System function - correct answer ✔✔pick up fluid lost from capillaries and returns it
to the blood.
Defense against pathogens
Primary lymphoid organs - correct answer ✔✔red bone marrow and thymus gland
Secondary lymphoid organs - correct answer ✔✔spleen and lymph nodes (tonsils)
Red bone marrow - correct answer ✔✔site of blood cell production
B cells mature here
Thymus Gland - correct answer ✔✔immature T cells from bone marrow move to thymus and
mature (most stay here: 95%)
Spleen - correct answer ✔✔Filled with white pulp (contains lymphocytes and red pulp)
filtering of erythrocytes
lymph nodes - correct answer ✔✔contain B cells, T cells, and macrophages
common in neck, armpits, and grain regions
Lymph vascular system (3 D's) - correct answer ✔✔drainage, delivery, and disposal
