Transcript Digestive_System_Purple

Function
• The function of the digestive system is to
break down food we eat into smaller parts
so the body can use them to build and
nourish cells and provide energy for our
body.
Stomach
•
•
•
•
•
J-shaped bag behind left lower rib.
12 in around the long side.
Muscle layers squeeze to mash food.
Holds three pints of drink and food.
Takes in/absorbs few nutrients that include
sugar.
• Makes mugus to protect itself from
digesting self.

Small Intestine
• Average width is 1.1-1.3 has three main
parts.
• Duodenum which is 10 inches
• Jejunum which is 88 inches
• Ileum which is 118 inches
• Inner surface has many folds called picae
• Receives digestive juices from pancreas
and liver.

Large Intestine
• Average width 2.3-2.7 inches
• First part is wide and has appendix and is
called caecum.
• Second part is ascending colon
• Third part is transverse colon
• Fourth is sigmoid
• Takes in water/ body salt and food

Liver
• The largest single organ inside the human
body.
• Wedge shaped, dark red color
• Typical weight 3.3 lbs. depth at widest part
on right side 6 inches
• Has a large right lobe and small left lobe.
• Lobes separated by a strong layer is the
falciform ligament
• Interesting fact- if you remove a damaged
part of the liver it can regenerate unlike
any other organ.

Gall Bladder
• Small pear shape organ that stores and
concentrates
• 3 to 4 inches long
• 1 inch wide
• Stores bile and concentrate
• Bile emulsifies fat and neutralize acid.

Pancreas
• Glandular organ that secretes digestive
enzymes
• Yellow
• 7 inches long 1.5 inches wide
• Produces enzymes
• Digest food and breaks down protein, fat,
and starch

Extras
• Anus- solid waste passes from the rectum in
order to leave your body
• Mouth- When food is chewed saliva starts
digesting carbohydrates.
• Esophagus- muscles in a process called
peristalsis push the food down into your
stomach.
• Rectum lower part of the large intestine where
feces are stored before they are excreted from
the body.
Villi and Micro Villi
• One of the numerous vascular projections
of the small intestine.
• Have finger like hairs move food.
• a microscopic projection of a tissue, cell,
or cell organelle; especially any of the
fingerlike outward projections of some
cells surfaces.
Diseases
• Alcohol induced liver disease-First, you
must stop drinking. Your doctor may
suggest changes in your diet and certain
vitamin supplements to help your liver
recover from the alcohol-related damage.
Alcohol-induced liver disease, as the
name implies, is caused by excessive
consumption of alcohol and is a common,
but preventable, disease.
Diseases
• Gallstones-If you have gallstones without
symptoms, you do not require treatment. If
you are having frequent gallbladder
attacks, your doctor will likely recommend
you have your gallbladder removed.
Gallstones are small, pebble-like
substances that develop in the gallbladder.
Gallstones form when liquid stored in the
gallbladder hardens into pieces of stonelike material
Diseases
• Acute and Chronic Hepatitis-When a person is first
infected with the hepatitis B virus, this is called an "acute
infection". A person may not have any symptoms or
she/he could become seriously ill. Most adults will
recover and get rid of the virus without any problems. If
the virus remains in the blood for more than six months,
then a person is diagnosed as having a "chronic
infection".
• Fortunately, most healthy adults (90%) who are
infected with the hepatitis B virus will recover and
develop protective antibodies against future
hepatitis B infections.
• Unfortunately, this is not true for infants and young
children — 90% of infants and up to 50% of young
children infected with hepatitis B will not get rid of
the virus and will develop a chronic infection. A
smaller number of infected adults (5-10%) will also
become chronically infected with hepatitis B.
Diseases
• Drug induced liver disease-Drug-induced
liver diseases are diseases of the liver that
are caused by physician-prescribed
medications, over-the-counter
medications, vitamins, hormones, herbs,
illicit ("recreational") drugs, and
environmental toxins-The most important
treatment for drug-induced liver disease is
stopping the drug that is causing the liver
disease.
What will happen?
• If your digestive system fails you will suffer
and possibly die from malnutrition.
Systems that it compliments
The digestive system can work with other systems in different ways. Lets give the
example of the liver. The liver does send nutrients around the body after the small
intestines absorb the nutrients and give it to the liver. The liver needs the help of
the circulatory system do it. So the blood vessels of the liver help the liver give
the nutrients to the body.
Vitamin K
• Needed for: Blood, Clotting and General
Health.
Vitamin C
• Needed for: Teeth, Gums, Bones, Blood,
Fighting Diseases, Skin and General
Health.
Vitamin D
• Needed for: Bones, Teeth, Nerves, Heart
and General Health.
Relations
• Circulatory system- helps circulate the
blood throughout the body
• Well the digestive system breaks down the
flood that flows through the circulatory
system to the muscular system which
provides movement to consume more
food.
• Nervous system gets a signal when you
are hungry.
• Foods are pulled down the digestive
system by the muscular system.
Relations Continued
• Secretary system brakes down and coats
the food so the muscles don’t have to
strain when receiving food down the
digestive system.
