During Moderate Exercise,increased Arterial $\mathrm { P } _ { \mathrm { CO } _ { 2 } }$

True/False

During moderate exercise,increased arterial $\mathrm { P } _ { \mathrm { CO } _ { 2 } }$ and hydrogen ion concentration and decreased arterial $P _ { o _ { 2 } }$ are all readily demonstrated,and thus are probably the signals for increased ventilation.
