Peyer patches
-lymphatic nodules in the mucus membrane
Paneth cells
-cells with pink granules
-secrete lysozymes, tumor necrosis factor-alpha, and defensins
at the base of crypts
Where are Paneth cells located?
True
The large intestine does not form villi, nor circular folds. T/F?
oral phase
–The bolus is collected at the back of the mouth; the tongue lifts the food upward until it touches the posterior wall of the pharynx.
pharyngeal phase
-food passes through pharynx to esophagus;
esophageal phase
-food enters and stretches the walls; causing the local & central nervous system reflexes to be triggered; i.e. peristalsis
lower esophageal sphincter does not relax to let the food into the stomach;
the esophagus contracts in an uncoordinated way
