THE MAIN STRUCTURE THAT PARTICIPATE IN THE DIGESTION OF
FOOD INCLUDE: - ANSWER ✓ the mouth, esophagus, stomach, small intestines,
and large intestines.
MOUTH - ANSWER ✓ food enters the mouth, where its taste triggers the saliva
glands to produce digestive enzymes, which begin the breakdown of
carbohydrates. The teeth chop and grind and the tongue mashes the food against
the hard palate, mixing it with saliva.
ESOPHAGUS - ANSWER ✓ A strong, muscular tube that connects the pharynx
to the stomach, it lies behind the trachea and in front of the spinal column. It is
composed of layers of muscle that contract to move the food. This action called
peristalsis, is controlled by the autonomic nervous system.
SPHINCTER - ANSWER ✓ which prevents the acidic content of the stomach
from backflowing into the esophagus.
STOMACH - ANSWER ✓ A muscular, elastic bag that fits under the diaphragm
on the left side of the abdomen and is protected by the lower ribs. Food usually
remains in the stomach for 2 to 4 hours while its muscles contract to mix it well
with digestive juices. The glands in the stomach release hydrochloric acid to kill
bacteria, pepsin to break down protein, and mucus to protect the stomach wall from
the acidic gastric juices.
, SMALL INTESTINE - ANSWER ✓ Also known as the small bowel, it consists of
three parts: duodenum, jejunum, and ileum. Once the food passes into the small
intestine, additional intestinal juices are added, including bile from the liver and
pancreatic juice from the pancreas.
LARGE INTESTINE - ANSWER ✓ also known as the large bowel. Nutrients and
water not absorbed in the small intestine are absorbed here. The large intestine
contains bacteria that work on the undigested substances and synthesize vitamin K
(essential for blood clotting), as well as some of the B - Complex vitamins
(promote various body functions).
APPENDICITIS - ANSWER ✓ is an inflammation of the appendix from unknown
causes. The only treatment is surgical removal (appendectomy).
ASCITES - ANSWER ✓ is not a disease, but a general term used to describe the
abnormal accumulation of fluid in the peritoneal cavity (space between the layers
of the membrane that lines the abdominal and pelvic cavities).
CIRRHOSIS - ANSWER ✓ is a group of chronic diseases that involve scarring of
liver tissue, which decreases the ability of the liver to perform its functions.
CHOLELETHIASIS - ANSWER ✓ is the presence of stomes in the gallbladder.
Cholecystitis is an inflammation of the gallbladder.
COLON CANCER - ANSWER ✓ involves an abnormal growth in the large
intestines that damages tissue and can cause a blockage of the digestive system.
CONSTIPATION - ANSWER ✓ is the inability to pass feces, the body's waste
that is passed through the anus. The most common causes are lack of dietary fiber,
inadequate fluids, certain medications, and lack of exercise.
DIARRHEA - ANSWER ✓ is the passage of frequent and watery stools. It can be
caused by certain diseases, stress, medications, and diet.
DIVERTICULOSIS - ANSWER ✓ is the wakening of the colon wall leading to an
outpouching in the wall. These diverticula can trap digestive material and become
infected. DIVERTICULITIS is an inflammation of the diverticula.
, GASTROENTERITIS - ANSWER ✓ is an inflammation of the mucous
membranes that line the stomach and intestines. Causes include food poisoning,
infection, and toxins.
GASTRITIS - ANSWER ✓ is when the lining of the stomach becomes inflamed
and can be caused by spicy foods and certain medications.
HEARTBURN - ANSWER ✓ occurs when the gastric juices back up through the
cardiac sphincter and irritate the lower end of the esophagus.
HEMORRHOIDS - ANSWER ✓ are painful, dilated veins in the lower rectum or
anus.
HEPATITIS - ANSWER ✓ is an inflammation of the liver caused by a virus or
poison.
PANCREATITIS - ANSWER ✓ is an inflammation of the pancreas that can be
caused by a variety of factors.
PERITONITIS - ANSWER ✓ is a condition in which the lining (peritoneum) of
the abdominal cavity becomes inflamed.
ULCER - ANSWER ✓ is an open sore in the lining of the digestive system. Pain
occurs when the protective lining is damaged and the acidic juices come into
contact with the delicate tissues underneath.
PEPTIC ULCER - ANSWER ✓ can occur in the stomach or duodenum
ULCERATIVE COLITISIS - ANSWER ✓ a severe inflammation of the colon
with the formation of ulcers and abscesses (collection of pus in a cavity).
URINARY SYSTEM - ANSWER ✓ eliminates excess water, salts, and waste
products from the body. It consists of the kidneys, ureters, urinary bladder, and
urethra.
