Anatomy PSW Exam Review Question
and answers correctly solved 2026/2027
Immune System - correct answer The immune system is a defense system that protects the body from
foreign agents
Nonspecific immune mechanisms or innate immunity - correct answer protect the body against many
different types of foreign agents and do not require recognition of the specific agent
Lines of defense - correct answer The first line of defense includes mechanical barriers, chemical
barriers, and reflexes. The second line of defense includes phagocytes inflammation, fever, protective
proteins and natural killer cells (NK cells)
Specific Immunity - correct answer Specific immunity (adaptive) protects the body against specific
foreign agents and requires recognition of the specific agent involved
T cells or T lymphocytes - correct answer They make up 70% to 80% of the blood's lymphocytes, they
engage in cell-mediated immunity (CMI).
Activated cytotoxic T cells and memory cells - correct answer produce a clone
Helper T cells - correct answer secrete cytokinesis and are necessary for activation of the cytotoxic T
cells
B cells or B lymphocytes - correct answer make up 20% to 30% of the blood's lymphocytes, the also
engage in antibody mediated immunity
Activated B cells - correct answer produce a clone of memory cells and plasma cells. The plasma cells
secrete antibodies that travel through the blood to the antigens located primarily in extracellular fluids
, Antibodies - correct answer immunoglobulins E (lgE) presents a serious problem with regard to an acute
allergic response
Genetic Immunity - correct answer A person is genetically immune to an antigen
Acquired immunity - correct answer a person can acquire immunity, by getting a disease or by receiving
antibodies from the mother across the placenta and or through breast milk, artificially acquired by the
use of a vaccine globulin made by another person or animal
Active immunity - correct answer means that a persons body makes the antibodies (usually long-lasting)
Allergic Responses - correct answer Allergic reactions are caused by the formations of antibodies to
substances usually not recognized as foreign
Delayed Onset Allergy - correct answer also called an immediate helper sensitivity reaction is often
caused by exposure to pollens and drugs such as penicillin. The most severe form is anaphylaxis.
Excretion - correct answer There are several organs of excretion: The kidneys, skin, lungs and intestines
The urinary systems - correct answer The urinary systems include the kidneys, ureters, urinary bladder
and urethra
Kidney - correct answer has three distinct regions the cortex, medulla, and pelvis, it has many functions,
it excretes nitrogenous waste, regulate blood volume, regulate electrocute concentration, regulate pH
and blood pressure and stimulate red blood cell production
Nephron Unit - correct answer is the functional urine making unit of the kidney
