TTU EX PHYS EXAM 3 – EXERCISE PHYSIOLOGY STUDY GUIDE, PRACTICE
QUESTIONS & REVIEW 2026/2027
function of respiratory system - ANS ✔✔conduct, warm, humidify and filter air. Adds moisture
intrapulmonary pressure - ANS ✔✔pressure within the lungs
atmospheric pressure - ANS ✔✔the pressure exerted by atoms and molecules in the atmosphere
surrounding Earth
muscles that cause inspiration - ANS ✔✔intercostals, scalene, sternocleidomastoid, pectoralis minor
muscles that cause expiration - ANS ✔✔internal intercostals, rectus abdominis, internal oblique,
transverse abdominis
Pulmonary Ventilation - ANS ✔✔movement of air into and out of the lungs
gas transport - ANS ✔✔movement of gases through blood
tidal volume - ANS ✔✔Amount of air that moves in and out of the lungs during a normal breath
residual volume - ANS ✔✔Amount of air remaining in the lungs after a forced exhalation
anatomical dead space - ANS ✔✔air that never reaches the alveoli, no gas exchange
alveolar ventilation - ANS ✔✔the amount of air that reaches the alveoli
factors that influence gas diffusion at the lungs - ANS ✔✔large surface area of alveoli, thin respiratory
membrane, difference in pressures.
breathing depth during exercise vs breathing frequency during exercise - ANS ✔✔increase in depth of
breathing occurs first at the onset of exercise.
increase in rate of breathing is secondary
factors that influence airflow - ANS ✔✔decreasing air resistance
Boyle's Law - ANS ✔✔describes how pressure of a gas tends to increase as the volume of the container
decreases
Dalton's law - ANS ✔✔each gas moves according to its own individual pressure.
total pressure of gas mixture = sum of partial pressures.
Fick's Law - ANS ✔✔Volume of gas that diffuses is proportional to surface area available for diffusion,
diffusion coefficient of gas, and the difference in partial pressure of gases
