• 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
