Question

The rate and depth of breathing influences the blood levels of oxygen (O2), carbon dioxide (CO2), hydrogen ions (H+), and also influences the venous return of blood and lymph due to changes in compression within the thoracic cavity that occur during breathing.

a) True
b) False

Answer 1

Answer:

True

Explanation:

True ,the rate and depth of breathing influences the blood levels of oxygen (O2), carbon dioxide (CO2), hydrogen ions (H+). Slow and deep breathing increase the blood oxygen level and cellular breathing is great,whereas the CO2 level reduces in the blood and it impedes lactic acid formation. Moreover,  influences the venous return of blood and lymph due to changes in compression within the thoracic cavity that occur during breathing.
