Response to exercise

• • The body reacts to the increased demand of energy
  • This energy comes from increased respiration
  • More oxygen is needed to be given to the working muscles
• • breathing rate and breath volume increase to get more oxygen to the blood
  • Heart rate increases to get oxygenated blood around the body faster
• • Vigorous exercise causee the body to not supply enough oxygen to the muscles
  • This causes anaerobic respiration to take place
  • long periods of exercise can cause muscle fatigue and stop them from contracting effectively
• • After exercise, due to anaerobic respiration, the body will fall into an oxygen debt
  • The incomplete oxidation of glucose causes build up of latic acid
  • An oxygen debt is the amount of extra oxygen needed to react with lactic acid and remove it from cells
  • Breathing rate and pulse are high to get more oxygen to blood, which then goes to the muscles
• • Blood that flows to muscles transports the lactic acid to the liver
  • The liver converts the lactic acid to glucose
