A syncytium is the collective contraction of the sheet or bundle of smooth muscle cells that make up a single-unit muscle.
Smooth muscle makes up the walls of hollow organs including the stomach, intestines, bladder, and uterus as well as the blood and lymphatic vessels, as well as the tracts of the respiratory, urinary, and reproductive systems.
