Bronchoconstriction (normal respiration) e. Pupillary constriction (normal visual field) f. Digestion (normal peristalsis and the absorption
The sympathetic nervous system controls the emergency nervous functions such as a. Tachycardia to increase blood flow to tissues in orer to supply more O2 (oxygen) and remove more CO2 (carbon dioxide) b. tachypnea to increase blood flow to tissues in order to supply more O2 and remove more CO2 c. Pallor due to vasoconstriction of t
