degistive

3. It refers to the mechanical
taking in of the food.
The normal route is through
the oral cavity or mouth.

4.  It is the breakdown of large molecules
into their component parts.
1. Mechanical Digestion - physical
breakdown of food into smaller
particles
2. Chemical Digestion - accomplished
by the digestive enzymes secreted
along the digestive tract

5.  The uptake of nutrient molecules in
the food.
 Absorption of the final products of
digestion takes place in the small
intestine.

6. During this process,

14. ESOPHAGUS
The esophagus is a muscular
tube through which food passes
from the pharynx to the stomach.
During the act of swallowing, the
bolus is transported by the
esophagus into the stomach via
wave-like contraction called
peristalsis.

located between the esophagus and the
small intestine.
It is a muscular, elastic, pear-shaped
organ that is about 30.5 cm long and
15.2 cm wide.
 It stores the swallowed food; mixes the
food with the digestive juice it
produces; and conveys its contents
slowly into the small intestine.

considered as the organ of
complete digestion and
absorption.
It is the longest organ of the
digestive system.
It is divided into 3 sections:
duodenum, jejunum, and ileum.

the next organ after the small
intestine.
 It is about 1.5 meters long and 5 cm
in diameter.
 It has 3 functions: temporary stores
fecal materials; absorbs vitamins in
the colon; and reabsorbs water from
the undigested residue.

large intestine.
It serves as warehouse for the undigested
residue or feces.
At the end part of the rectum is the anal
canal or anus that functions as the exit
for fecal materials.
