@gethelpwithproctoredexam: Digestion begins in the mouth, where food is chewed and mixed with saliva containing amylase to start carbohydrate breakdown and form a bolus. The esophagus moves the bolus to the stomach by peristalsis. In the stomach, acids and enzymes digest proteins and mix food into chyme. The small intestine completes digestion using bile and pancreatic enzymes and absorbs nutrients through villi. The large intestine reabsorbs water and forms feces, which are stored in the rectum and eliminated through the anus. #nursing #student #study #nurse #nursingstudent
