As food enters the mouth it is chewed to Increase the surface area
The food is mixed with saliva in the salivary gland.
Contains the enzyme salivary amylase
Chemical digestion of carbohydrates
Chewed food is now termed as bolus
travels down the esophagus by means of peristalisis
the enterance of stomach
Lower esophegal sphincter muscle
Re-entering the esophagus
Hydrochloric acid it is turned into a liquid material called chyme.
Depending on the composition of the meal.
In the stomach the digestion of protein begins
Pyloric sphincter
Bicarbonate in the gastric juice.
Digestive enzyme that breaks down energy yielding nutrients.
The beginning of the small intestine is called the duedenum. When fat enters the beginning of the small intestine a hormone is released.
This travels through the blood into the gall bladder. This is originally produced by liver and the job is to Emulsy the fat.
Carbohydrates are broken down into smaller subunits called monosaccharides, fats to fatty acids, protein to amino acids. These are absorbed through intestinal lining by simple diffusion, facilitated diffusion and active transport.
Absorption occurs mainly in the middle and lower portion of small intestine namely jejunum and ileum.
The remaining material is sent through ileocecal valve into large intestine.
In the large intestine bacteria feeds into undigested food produces vitamins.
The remaining waste which includes indigestible fiber waits for excretion. The voluntary muscle holds the material in the rectum is called anal sphincter.
