2024/2025 BIOS255 COMPREHENSIVE
EXAM WITH CORRECT ANSWERS
Function of nervous system - CORRECT ANSWERS- -Control of body's
internal environment to maintain 'homeostasis'
-Programming of spinal cord reflexes
-Memory and learning
-Voluntary control of movement
cardiac cycle - CORRECT ANSWERS- A complete heartbeat consisting of
contraction and relaxation of both atria and both ventricles
innate and adaptive immunity - CORRECT ANSWERS- innate/natural- general
immune response, monocytes, neutrophils, NK cells
adaptive immunity- antigen specific response, B cells, T cells
humoral/cell-mediated are actually parts of both systems
CD4 t helper cells - CORRECT ANSWERS- T-cell needed for both humoral and
cellular immunity. Recognize antigens.
Artificially acquired passive immunity - CORRECT ANSWERS- antibodies
gathered from a human or other animal and are injected into an individual.
Ex.) antiserum for a snakebite, rabies
, inspiratory capacity - CORRECT ANSWERS- tidal volume + inspiratory
reserve volume
Brain and forceful breathing - CORRECT ANSWERS- controlled by medulla
oblongata
types of respiration - CORRECT ANSWERS- external, internal, cellular
External respiration is the breathing process. It involves inhalation and
exhalation of gases.
Internal respiration involves gas exchange between the blood and body cells.
Cellular respiration involves the conversion of food to energy.
alveoli and capillaries - CORRECT ANSWERS- site of gas exchange
Sacromere - CORRECT ANSWERS- unit of a muscle fiber
what increases hemoglobin - CORRECT ANSWERS- high altitudes
function of surfactant - CORRECT ANSWERS- Thin layer of fluid that covers
the alveoli.
Reduces surface tension of the fluid layer lining the alveoli, preventing the
alveoli from collapsing during exhalation.
Type II alveolar cells - CORRECT ANSWERS- secrete surfactant
