During a meal, the parasympathetic division activates digestion by increasing blood flow to the digestive system and releasing digestive enzymes. At the same time, it slows down heart rate and respiratory rate. During exercise, the sympathetic division is activated, which inhibits digestion and redirects blood flow to the skeletal muscles, increasing heart rate and respiratory rate to supply more oxygen to the body.
