The inhalation and exhalation are two characteristics of respiratory function. Please explain the concept of ventilation versus respiration, and explain the characteristics of inspiration and expiration in terms of involved organs and the forces triggering them.
Describe the specific events of the ventilation process. Be sure to include all additional structures that contribute to ventilation.
Explain why ventilation is not 100% voluntary. (HINT: CO2)
What is spirometry?
during the inspiration phase of pulmonary ventilation which of the following occurs first? increase in lung volume, contraction of respiratory muscles, movement of air into the lungs, or decrease in intrapulmonary pressure.

Suppose the person exercises, so that tidal volume increases to 4000 mL, dead space increases to 300 mL due to dilation of the respiratory passageways, and respiratory rate increases to 24 breaths per minute. What is the alveolar ventilation then? How is the change in alveolar ventilation beneficial for doing exercise?arrow_forward
- Callisto is hiding from Xena under a pile of leaves. She is worried that if she takes slow, deep breaths (tidal volume = 650 mL, breathing rate = 11/min), the pile of leaves will move up and down, and Xena will notice her. Therefore, she takes rapid, shallow breaths (tidal volume = 210 mL, breathing rate = 25/min). Please note anatomical dead space = 150mL Determine Xena’s alveolar ventilation in both cases and discuss which breathing pattern provides better oxygen supply to her body. Show your calculations.arrow_forwardWhy must a person floating on the surface of the water and breathing through a snorkel increase his/her tidal volume and/or breathing frequency if alveolar ventilation is to remain normal? answer brieflyarrow_forward
