Injestion |
Taking in of food orally into the body |
|
|
Peristalsis |
Coordinated rhythmic serial contraction of smooth muscle that forces food through the digestive tract |
|
|
Secretion |
The release if chemical substances manufactured ilby cells of glandular organs |
|
|
Mechanical Digestion |
Chewing (mouth), churning (stomach), segmentations (small intestine) |
|
|
Chemical Digestion |
Enzymes secreted throughout the digestive tract that break down bonds that hold food particles together |
|
|
Absorption |
The way substances pass across tissue. Moving products of digestion into the blood |
|
|
Elimination |
Removal of waste products from body |
|
|
Mouth |
Teeth chew food, tongue facilitates chewing and swallowing |
|
|
Salivary Glands |
Secrete saliva which helps mouth soften and moisten food |
|
|
Pharynx |
Directs food into the esophagus and closes any possible entries into the nasal and respiratory tracts |
|
|
Esophagus |
Carries food from pharynx to stomach |
|
|

|
|
Gallbladder |
Concentrates and stores bile |
|
|
Stomach |
Secretes gastric juice, mechanical digestion, absorbs small amount of water and dissolved substances, chemical digestion |
|
|
Large Intestine |
Absorbs water and electrolytes, synthesis of of certain vitamins, temporary storage of waste, elimination of waste |
|
|
Small Intestine |

|
|
Serosa |
Outermost layer of digestive tract, help anchor digestive organs, carry blood vessels, lymph vessels and nerves to abdominal organs |
|
|
Submucosa |
Contains blood vessels, nerves, glands, and lymphatic vessels; restricts spread of vessel |
|
|
Mucosa |
Lining of tract, main job is digestion and absorption |
|
|

|
|
Anabolism |
Building of larger, more complex substances from smaller substances |
|
|
Bile |
Greenish-yellow enzyme provided by liver and stored in the gallbladder. Plays important role in fat digestion and absorption of fat soluble vitamins |
|
|
Amylase |
Digests carbohydrates |
|
|
Lipase |

|
|
Protase |
Digests proteins |
|
|
Carbohydrates |
Body's primary source of energy |
|
|
