Digestive Concept Map Alejandra Mendez Period 5
Major functions of the digestive system
Absorption
Absorption is when the small molecules are absorbed into the body
Digestion
Digestion is the breakdown of food into small molecules
Digestive enzymes
Pepsin
produced in the stomach
helps break down proteins into amino acids
Trypsin
produced in the pancreas
breaks down proteins
Amylase
produced in the mouth
It helps break down large starch molecules into smaller sugar molecules
Pancreatic lipase
produced in the pancreas
It is used to break apart fats
Deoxyribonuclease and ribonuclease
produced in the pancreas
They are enzymes that break bonds in nucleic acids like DNA and RNA
Disorders of the digestive system
Inflammatory Bowel Disease
Disorders that involve chronic inflammation of your digestive tract
This condition involves inflammation and sores along the superficial lining of your large intestine and rectum
Peptic Ulcer Disease
condition in which painful sores or ulcers develop in the lining of the stomach
the first part of the small intestine (the duodenum)
a thick layer of mucus protects the stomach lining from the effect of its digestive juices
Gastroesophageal Reflux Disease
a digestive disorder that occurs when acidic stomach juices, or food and fluids back up from the stomach into the esophagus
affects people of all ages
People with asthma are at higher risk of developing
Layers of the GI tract
Submucosa
the layer of areolar connective tissue lying beneath a mucous membrane
Muscularis propria
smooth muscle layer
Two layers
the inner layer is circular
the outer layer is longitudinal
smooth muscle are used for peristalsis
to move food down through the gut
Mucosa
The moist, inner lining of some organs and body cavities
Glands in the mucosa make mucus
Also called mucous membrane
Serosa
The outer lining of organs and body cavities of the abdomen and chest
Also called serous membrane
Location of digestion and absorption of each macromolecule
Small intestine and Pancreas
both produce variety of digestive enzymes
Responsible for breaking down many macromolecules found in small intestine
Major organs of the digestive system
Esophagus
the part of the alimentary canal that connects the throat to the stomach
It is a muscular tube lined with mucous membrane
Stomach
The internal organ in which the major part of the digestion of food occurs
a pear-shaped enlargement of the alimentary canal linking the esophagus to the small intestine
Mouth
Chewing into small macromolecules
Small intestine
A long tube-like organ that connects the stomach and the large intestine
It is about 20 feet long and folds many times to fit inside the abdomen
Large intestine
much broader than the small intestine
takes a much straighter path through your belly, or abdomen
to absorb water and salts from the material that has not been digested as food
get rid of any waste products left over
Anus
The opening at the end of the alimentary canal
Where solid waste matter leaves the body
