Your Digestive SystemYour Digestive System

Mouth Esophagus Stomach Small Intestine Large Intestine Rectum Anus

The Oral CavityThe Oral Cavity

Mechanical digestion begins in the mouth…grinding food.

Salivary glands begin the process of chemical digestion….salivary amylase splits starch molecules.

The EsophagusThe Esophagus

The hallway that funnels food into the stomach.

Peristalsis: relaxing and contracting of muscle to push food into the stomach.

Sphincter: the “door” into the stomach.

The StomachThe Stomach

The storehouse for masticated food.

Enzymes pepsinogen and hydrochloric acid begin the breakdown into smaller particles.

The liver produces bile to break down fat.

All of these contents (food, enzymes, bile, acid are called chyme.

Small IntestineSmall Intestine

Divided into 3 sections:

1.Duodenum 2.Jejunum: most

digestion occurs here 3.Ileum The lining is variegated

with peaks called villi. Nutrients are

absorbed into the bloodstream after 3-10 hours.

Large IntestineLarge Intestine

The lining is smooth. This is the site where

water is absorbed from waste, turning it to solid feces.

Bacteria here can manufacture vitamin k and biotin.

RectumRectum

Stores feces until elimination.Total intestinal transit time 24 hour to

3 weeks.

The Dental ConnectionThe Dental Connection

Oral cavity is the window for viewing internal health.

Rapid metabolic turnover rate is earliest indicator of depleting vital nutrients.

Educational training and frequent patient contact make dental hygiene the ideal health care provider to screen dietary/nutritional deficiencies.
