Q

What does the increase in heart rate and breathing rate do?

A

supply the muscles with more oxygen and glucose for increase in aerobic respiration

17
Q

What happens during periods of vigorous excersise?

A

the muscles may not get supplied with enough oxygen so anaerobic respiration starts to take place in muscle cells

18
Q

What does lactic acid do?

A

causes the muscles to hurt and stops them contracting efficiently

19
Q

What is lactic acid?

A

a poison so needs to be removed quickly
