What are the steps to the pigs digestive systems?

Answer 1

1.) Food enters the oral cavity

2.) Passes through pharynx

3.) Enters esophagus via glottis

4.) Involuntary wave of smooth muscular contractions (peristalsis) moves food down esophagus to cardiac stomach (food broken down by muscular contractions and gastric juices...hydrochloric acid and pepsin)

5.) pyloric stomach

6. small intestine via pyloric sphincter

-duodenum: digested food mixes with enzyme secreted by intestinal epithelium, bile form gallbladder, and enzymes of pancreas

-jejunum: chemical digestion and nutrient absorption takes place

-ileum

7.) enter large intestine via muscular sphincter

caecum: fermentation reservoir where cellulose is digested

-colon:

-descending colon

-rectum

*water reabsorbed form wastes of digestive tract, feces becomes more solid

8.) fecal matter expelled through anus
