Salivary Glands
The mouth contains the salivary glands, which is a digestive gland. The salivary glands
produce a liquid substance called saliva. The saliva acts as a cleanser to the teeth by
dissolving food particles so that they may be eaten. Saliva also contains enzymes and
mucus. There are three major pairs of salivary glands. The parotid gland carries its
contents and drains the mouth. The submandibular gland empties its contents on the floor
of the mouth on both sides. The sublingual gland process several small sublingual ducts
that are released onto the floor of the mouth in an area posterior to the submandibular
ducts.
Esophagus
The esophagus is a muscular tube, which carries food and liquids from the throat to the
stomach for digestion after it has been chewed. The food then travels downward toward
the stomach by strong waves of muscles that are contracting through the walls of the
esophagus. If you have eaten any food that is bad or something that is poison the stomach
will make it all travel all the way back up the esophagus and you will start throwing it up.
This procedure is called vomiting.
Stomach
Connected to the esophagus is an organ called the "stomach". Which consists of layers of
muscles. The stomach breaks down food, which began in the mouth. It also acts as a
storage compartment. Some of its functions are the following. (1) Holds a meal in the
upper portion and releases it a little at a time into the lower portion for processing. (2)
The muscles contract and mash the food into a sticky, slushy mass. (3) The cells in the
stomach produce acid that kills germs
Liver
The liver cleanses the blood circulating throughout your body and processes nutritional
molecules, which are given out to the tissues. The liver is located at the top of the
abdomen, just below the diaphragm and has two main lobes. The liver is also known as a
"gland".
Large Intestines
The large intestine absorbs fluids and recycles them into the blood stream and compacts
the waste in to fences. Fences are about ¾ water and ¼ protein, fat, undigested food dried
digestive juices and dead bacteria.
Small Intestines
Small intestines are looped back and forth upon itself and is held in place by tissues
which are attached to the abdominal wall .The small intestine has a receiving area for
chemicals and partially digested food from the stomach, most of the nutrients area
absorbed into the blood and the liquids and bodily waste everyday.
Appendix
Most digestion takes place almost continuously in a watery, slushy environment. The
large intestine absorbs water from its inner contents and stores the rest until it is
convenient to dispose of it. Attached to the first of the large intestine is a troublesome
pouch called the (vermiform) appendix. The appendix has no function in a modern day
human, but it is believed that it has been lots of help to our primitive ancestors.
Rectum
The rectum is a short, muscular tube that forms the lowest portion of the large intestine
and connects it to the anus, Feces collects here until pressure on the rectal walls cause
nerve impulses to pass the brain, which then sends messages to the voluntary muscles in
the anus relax, permitting expulsion.
