•
widespread effects on circulation, muscles and sugar metabolism • raised heart rate •
increased heart output •
increased rate and depth of breathing •
increased metabolic rate •
increased force of muscular contraction • delayed muscular fatigue • reduced
blood flow to bladder (muscular walls relax and sphincters contract) • reduced
blood flow to intestines •
increased blood pressure •
increased sugar (glucose) in the
blood •
increased break - down of glucose for energy *, especially in muscle cells •
increased free fatty acids in the
blood * • more oxidation of fatty acids to produce energy * • more ATP (the cells» primary energy compound) produced * •
blood vessels constrict
