What do beta blockers do?
Beta Receptors To best explain what a beta blocker does, you need to understand a little bit about the nervous system and what beta receptors are. A beta receptor is a protein molecule that processes specific messages carried by the central nervous system and various hormones. There are a variety of different types of beta receptors. They are mostly found in the heart and blood vessels. Their job is to increase blood pressure when stimulated. There are three types of beta receptors–Beta 1, which are found in the brain and the heart, Beta 2, which are found in the lungs, blood vessels and muscles, and Beta 3, which are found in the fat cells. Beta blockers are used primarily for blocking B1 and B2 receptors. Beta 1 is responsible for your heart rate. Beta 2 is responsible for the smooth muscles, which are muscles you have no control over such as the heart. Uses Beta blockers are widely known as beta-adrenergic blocking agents, these block adrenaline from binding to the beta receptors o
