(2026) Complete Questions and 100%
Correct Answers (verified)
• What does the Respiratory Zone do? -✓✓Allow inhaled oxygen to diffuse into the lung
capillaries in exchange for CO2
• Conducting Zone -✓✓nose, pharynx, larynx, trachea, bronchi, bronchioles
• What does conducting zone do? -✓✓conducts air to respiratory zone, humidifies,
warms, and filters air
• Most common cancer mutation? -✓✓Acquired
• What does anticholinergic mean? -✓✓blockade of muscarinic receptors - This inhibits
nerve impulses responsible for involuntary muscle movements and various bodily
functions
• What does dopamine do? -✓✓influences movement, learning, attention, and emotion.
Dopamine enables neurons in your brain to communicate and control movement.
• What does messenger RNA do? -✓✓Transcribes information from the DNA in the
nucleus and carries it to the cytoplasm, and then to the ribosome. Single-stranded,
intermediate molecule. Carries the instructions for making proteins.
• What do ribosomes do? -✓✓Make proteins (protein synthesis)
• Neurotransmitters -✓✓chemical messengers that cross the synaptic gaps between
neurons
• Neurotransmitters at the parasympathetic postganglionic synapses -✓✓Acetylcholine
and nitric oxide
• Atropine Neurotransmitters -✓✓Atropine is a muscarinic receptor antagonist that is
used to inhibit the effects of excessive vagal activation on the heart, which is manifested
as sinus bradycardia and AV nodal block. Therefore, atropine can temporarily revert
sinus bradycardia to normal sinus rhythm and reverse AV nodal blocks by removing
vagal influences.
• alpha adreneric receptors -✓✓
