Q

If ventilation is stopped (i.e. while holding your breath), oxygen gas levels remain the same in the blood, but carbon dioxide levels increase.
T or F?

A

T or F?

A

True

24
Q

External respiration normally matches the rate of internal respiration.
T or F?

A

25
Q

Internal respiration is the process by which molecules of oxygen and carbon dioxide gases are exchanged at the lungs.
T or F?

A

False

T or F?

A

True

31
Q

45
Q

Food molecules for which there is no digestive enzyme will remain outside the body, in the lumen of the alimentary canal.
T or F?

A

True

46
