KINE 433 Exam 1 Questions with Verified Answers
pulmonary ventilation Ans✓✓ -movement of air into and out of the lungs
pulmonary diffusion Ans✓✓ -the exchange of oxygen and carbon dioxide
between the lungs and the blood
capillary diffusion Ans✓✓ -the exchange of oxygen and carbon dioxide between
the capillary blood and metabolically active issues
which two processes are considered external respiration Ans✓✓ -pulmonary
ventilation and pulmonary diffusion
What is external respirartion Ans✓✓ -the movement of gases from outside the
body into the lungs and then the blood
internal respiration Ans✓✓ -the exchange between the blood and the tissues
from the nose and mouth where does the air travel through? (serve as the transport
zone of the lungs b/c gas exchange doesn't occur here) Ans✓✓ -pharynx, larynx,
trachea, and bronchial tree
smallest respiratory units Ans✓✓ -respiratory bronchioles and alveoli
What happens when the air finally reaches the smallest respiratory units? Ans✓✓
-exchange of oxygen and carbon dioxide
, respiratory zone Ans✓✓ -the site of gas exchange in the lungs
Why is breathing through the nose important? Ans✓✓ -helps humidify and warm
the air during inhalation and filters out foreign particles from the air
sympathetic nervous system Ans✓✓ -part of the autonomic nervous system;
activates the fight or flight reflex; intense physical activity
autonomic nervous system Ans✓✓ -includes both SNS and PNS
parasympathetic nervous system Ans✓✓ -relaxes the body and slows high
energy systems down
Macrocirculation Ans✓✓ -outside the tissues; arteries & veins; provides
bloodflow to & from tissues
Microcirculation Ans✓✓ -completely encased in a tissue; arterioles, capillaries,
venules; regulate BF & BP; regulates exchange of O2, CO2, and nutrients
How does the central circulatory adjust to exercise? Ans✓✓ -cardiac output
increases; redistribute cardiac ouput; increase venous return (blood leaving the
heart better be matched by blood returning)
Heart: Ans✓✓ -self-regulating; spontaneous; rhythmic; highly regulated; fatigue
resistant
