Smooth Muscle0 Can be found in your digestive system,
circulatory system, and even the muscles in your eyes that help them to focus.
0 Smooth muscle tissue is located in the walls of hollow internal structures such as blood vessels, the stomach, intestines, and urinary bladder

0 The muscle of the arteries contracts and relaxes to regulate the blood pressure and the flow of blood.
0 Involuntary
