Movements of the Large Intestine Flashcards
gastroenteritis and gastroileal reflexes move material into cecum
while you eat
movement from cecum to transverse colon is
very slow
very slow movement from cecum to transverse colon allows for
hours of water absorption
peristalic waves
move material along the length of the colon
segmentation movements also known as
haustral churning
segmentation movements
mix contents of adjacent haustra
movements from transverse colon through rest of large intestine results from
powerful peristaltic contractions
stimulus is
a distention of stomach and duodenum and is relayed over intestinal nerve plexus
distention of rectal wall triggers
defecation reflex
defecation reflex are
two positive feedback loops which are triggered by stretch receptors in the rectum
