Opposed circular and longitudinal muscles enable peristaltic motion. Using a entrance end means that this Component of the human body encounters stimuli, such as meals, favouring cephalisation, the development of the head with perception organs along with a mouth. Lots of bilaterians have a combination of circular muscles that constrict the body, making it longer, and an opposing set of longitudinal muscles, that shorten your body;[133] these empower comfortable-bodied animals with a hydrostatic skeleton to move by peristalsis.
