Esophagus
  • The esophagus is a muscular tube connecting the
    throat pharynx with the stomach. The esophagus is
    about 8 inches long, and is lined by moist pink
    tissue called mucosa. The esophagus runs behind
    the windpipe trachea and heart, and in front of
    the spine. Just before entering the stomach, the
    esophagus passes through the diaphragm.

4
Stomach
  • The stomach is a muscular hollow, dilated part
    of the Digestion System which Orgon functions as
    an important of the digestive tract in some
    animals including vertebrates echinoderms insects
    mid-gut and molluscs. It is involved in the
    second phase of digestion following mastication
    chewing.

5
Small Intestine
The intestines are a long continuous tube running
from the stomach to the anus. Most absorption of
nutrients and water happen in the intestines. The
intestines include the small intestine large
intestine, and rectum. The small intestine small
bowel is about 20 feet long and about an inch in
diameter. Its job is to absorb most of the
nutrients from what we eat and drink. Velvety
tissue lines the small intestine, which is
divided into the duodenum Jejunum and Ileum.
6
Large Intestine
  • The mucosa of the large intestine is punctuated
    with numerous crypts that absorb water and are
    lined with mucus secreting goblet cells. At the
    lower end of the rectum the circular and
    longitudinal muscle layers terminate in the
    internal and external anal sphincters.

7
Liver
  • The liver is a large meaty organ that sits on the
    right side of the belly. Weighing about 3 pounds
    the liver is reddish brown in color and feels
    rubbery to the touch. Normally you can't feel the
    liver because it's protected by the rib cage.
  • The liver has two large sections, called the
    right and the left lobes. The gallbladder sits
    under the liver along with parts of the pancreas
    and intestines. The liver and these organs work
    together to digest absorb, and process food.

8
Appendix

The appendix sits at the junction of the small
intestine and large intestine. Its a thin tube
about four inches long. Normally the appendix
sits in the lower right abdomen.
