1. The Parasympathetic Nervous System will take care of you after meals. The effects include a slowed heart rate and breathing and improved digestion.
ORGANS CONCERNED: Stomach, small intestine, large intestine, liver, gallbladder, heart, and lungs
MAJOR NERVE SUPPLY: Vagus Nerve (X)
EFFECTS:
Stomach and intestines - improved motility and gastric secretions to aid digestion
Liver - increased bile secretion and regulates homeostasis
Gall bladder - regulates contractions and urine passage
Heart - controls heart rate regulation
Lungs - regulates respiration and modulates pulmonary function and bronchi are tightened
