What tissue is found in the walls of the small intestine uterus bladder and veins?

The tissue found in the walls of the small intestine, uterus, bladder, and veins is primarily smooth muscle tissue. This type of muscle is responsible for involuntary movements and is essential for functions such as peristalsis in the intestines, contractions during childbirth in the uterus, and the regulation of blood flow in veins. Smooth muscle allows these organs to function effectively without conscious control.
