Which of the following is/are true while you are holding your breath? alveolar PCO2 is decreasing alveolar PO2 is increasing alveolar air pressure is equal to atmospheric pressure
Added by Ruby J.
Step 1
Alveolar PCO2 is decreasing: This is false. When you hold your breath, the carbon dioxide (CO2) produced by your body's metabolic processes has nowhere to go, so it accumulates in your alveoli, causing the partial pressure of CO2 (PCO2) to increase. Show more…

QUESTION 36 Which of the following is true when we exhale? (Select all that apply) - The air pressure inside the lungs is lower than the air pressure outside the body. - The volume of the thoracic cavity decreases. - The diaphragm contracts to force air out of the lungs. QUESTION 37 The carbon dioxide we exhale while breathing is a product of cellular respiration.
