Have you ever wondered what causes your heart to beat or your lungs to breathe? These are examples of involuntary responsesno post the brain controls without the need for conscious thought. The autonomic nervous system (ANS) works using a balance of the sympathetic and parasympathetic nervous systems that regulate the body’s involuntary functions, including heart rate, respiratory rate, digestion, and sweating. Many medications are used to control various cardiovascular, respiratory, and gastrointestinal conditions by acting on ANS receptors. Beta blockers and anticholinergic medications are the most commonly prescribed medications in this category.
