The main organs are the brain and the spinal cord. The brain tells evrything what to do and sends messages to the body. The balance of activity between the sympathetic and parasympathetic systemsare controlled by the central nervous system. Sympathetic and Parasympathetic Divisions The sympathtic system responds to the body's needs during increased activity and in emergencies. The parasympathetic system opposes the actions of the sympathetic nervous system. regulates automatic bodily processes such as breathing and digestion without concious control by the brain Autonomic Nervous System it also is responsible for homeostasis The Digestive System The Digestive System is where your food is broken down. The food travels down the esophagus into the stomach and intestines where ot is digested. Nerve supply to the stomach is provided by both sympathetic and parasympathetic divisions. The Excretory System The Excretory system creates stores and carries urine. It also excretes waste from your body to keep the water and chemicals in your body balanced. The functions of the urinary bladder depend entirely on the autonomic nervous system. Urine is retained by activation of sympathetic pathways. Current Research What is being done?
