Final answer:
Smooth muscle tissue is found in the gastrointestinal tract, blood vessels, urinary bladder, and uterus. It is responsible for involuntary movements and contractions in these organs.
Step-by-step explanation:
Smooth muscle tissue is found in various parts of the body, including the gastrointestinal tract, blood vessels, urinary bladder, and uterus. It is also present in the respiratory tract and other hollow organs. Smooth muscle is involuntary and nonstriated, meaning it does not have the striped appearance of skeletal muscle. It is responsible for the involuntary movements and contractions of these organs and vessels. Smooth muscle is a type of involuntary, nonstriated muscle found throughout various systems in the body. It is present in the walls of hollow organs including the gastrointestinal tract (intestines and stomach), blood vessels, urinary bladder, and uterus. This muscle tissue is responsible for contraction and movement of these organs, functioning under the control of the autonomic nervous system. Smooth muscle cells feature a single nucleus and lack the visible striations seen in skeletal and cardiac muscle, giving them a uniform appearance.
