Question 27

``` Sympathetic effects on Heart Lungs Pupil reaction Glucose GI activity Sphincter Blood flow ```

Answer 27

Heart: rate increase, pump increase, automaticity, BP Lungs: rate increase, depth increase, SpO2 increase, bronchodilation, decrease secretions Pupil reaction: dilate, increase pressure in back of eye Glucose: Breakdown of glycogen into fuel, blood glucose levels increase GI activity: Decreased movement, decreased secretions, decreased blood flow to tract Sphincter: bladder sphincter contracts Blood flow: Vasoconstriction, flow increases to where the body needs it

Question 28

``` Parasympathetic effects on Heart Lungs Pupil reaction Glucose GI activity Sphincter Blood flow ```

Answer 28

Heart: rate decrease, pump decrease, BP decrease Lungs: rate decrease, depth decrease, increased secretions, bronchoconstriction Pupil reaction: constrict Glucose: Glucose becomes storage, lower blood glucose levels GI activity: Increased motility, increased secretions Sphincter: Sphincters relax Blood flow: Vasodilation, goes to periphery
