What is Response to Exercise?
"Body response to exercise involves increases in heart rate and breathing rate to supply muscles with more oxygen and glucose for respiration."
Why does heart rate increase during exercise?
Where is lactic acid transported after exercise so it can be converted back into glucose?
Choose the correct answer: which change happens during exercise to help supply more oxygen to muscles?
Which change happens during exercise to help supply more oxygen to muscles?
Physiological Changes
Heart rate, breathing rate, and breath volume all increase to supply muscles with more oxygenated blood.
Blood flow is diverted towards the muscles and away from the digestive system.
Lactic acid is transported to the liver where it is converted back into glucose.
