{{Main|Smooth muscle}}
Smooth muscle contraction is regulated by the autonomic [[nervous system]], [[hormone]]s, and local chemical signals, allowing for gradual and sustained contractions. This type of [[muscle tissue]] is also capable of adapting to different levels of stretch and tension, which is important for maintaining proper blood flow and the movement of materials through the [[Human digestive system|digestive system]].
