Digestive System Flashcards
What are the 3 salivary glands
Sublingual
Submandibular
Parotid
They produce saliva amylase which help to moisten food and breakdown complex carbohydrates into simple carbohydrates
What are the 3 main functions of digestion
Breakdown food
Absorption
Eliminate waste
What is peristalsis
A muscular wave that travels the length of the GI tract
What are the 3 main processes to move and mix food
Swallowing
Peristalsis
Segmentation
What happens in the Large Intestine
Absorption of water and vitamins B & K
Where does Mechanical digestion take place
They begin with the breakdown of food into smaller pieces by chewing of food by the teeth and continue through the muscular mixing of food by the stomach and intestines
Where does chemical digestion take place
It begins in the mouth with the mixing of salivary amylase
The bulk of the chemical digestion takes place in the small intestine thanks to the pancreas
What substance in the mouth contains enzymes that begin chemical digestion
It begins with salivary amylase which breakdown complex carbohydrates into simple carbohydrates
The passing of the mass of food into the stomach from the esophagus
bonus
Passing of food from the stomach which has mixed Amylase and hydrchloric acid and digestive enzymes (pepsin)
Chyme
What is digestion
The process of turning large pieces of food into its component chemicals
Mechanical & Chemical
What organ products bile
The liver
What organ stores bile
Gallbladder
Where are villi and where are they found
innumerable small folds on the intestinal wall, that massively increase the surface area of the small intestine to ensure efficient and rapid absorption of nutrients.
Which organ produces enzymes that break down proteins
Two “solid” digestive organs, the liver and the pancreas, produce digestive juices that reach the intestine through small tubes called ducts
What is a Bolus
The passing of the mass of food into the stomach from the esophagus
What is Chyme
Passing of food from the stomach, which has mixed Amylase and hydrchloric acid and digestive enzymes (pepsin)
What are the 3 funtionas of the digestive system
Breakdown of food
Absorbing nutrients
Eliminating waste
