What responses in body systems will occur to increase the oxygen received by muscle tissue when a man runs a marathon race?
Responses
The endocrine system releases stress hormones, decreasing heart rate and rate of digestion
The muscular system is nourished by the release of calcium from the skeletal system
Respiration rates increase and heart rate increases, circulating blood at a faster pace
The nervous system increases the rate of neurotransmissions to decrease muscle movement
The cardiovascular system works harder to pump oxygen-rich blood to muscle tissues
The respiratory system increases breathing rate and depth to take in more oxygen and eliminate carbon dioxide
The temperature regulation system may increase sweating to cool the body and prevent overheating
The digestive system slows down to redirect energy and blood flow to the working muscles
