25
Peristalsis
Wave like contraction in which material is propelled from point to point along the Gastro intestinal tract. These are rings of contractions.
26
Segmentation
A peristaltic movement of Contractions that assist in mixing and just material with digestive juices and help continue the mechanical breakdown of larger particles
27
Deciduous teeth
Set of 20 baby teeth 6 to 30 months old
28
Permanent teeth
Permanent teeth usually complete between 17 and 24 years old
29
Pharynx
Connect esophagus to stomach has three components, nasopharynx oropharynx, which is most involved in swallowing and the laryngopharynx
30
Swallowing
And involuntary movement controlled by the motor cortex in a cerebrum
31
Salivary gland secretions to mouth
Via submandibular duct
32
Stomach structure
Esophagus enters stomach in the area of Gastroesphageal opening. Where lower esophageal (LES) Sphincter AKA cardiac sphincter is located. Top of stomach is called fundus, followed by body of stomach. Lower end of stomach is called the pylorus. Before entering, the small intestine food must go through the pyloric sphincter the stomach expands after a large meal it is about the size of a large sausage, when empty
33
Rugae
Folds in lining of stomach
34
Backflow is prevented by
Sphincters and valves
35
Three layers of the stomach wall
Longitudinal muscle, circular muscle and oblique muscle layers. All are smooth muscle.
36
Walls of the small intestine
folds of the mucosa are called plica. Villi fingers) are located in these folds, they increase the surface area for absorption of nutrients
37
Liver
The liver is the largest gland it secretes bile which is stored in gallbladder
38
CCK
Stands for cholecystokinin a hormone which triggers gallbladder to release bile
39
Chyme
Food that is staring to be digested as it is traveling thru GI tract
40
Gallbladder
Store’s bile Located under liver Releases bile into small intestine
41
Bile
Breaks down lipids. CCK (hormone) triggers gallbladder to release bile into small intestine
42
Pancreas
It is an exocrine gland, that lies behind the stomach pancreatic cells, secrete pancreatic juices, these digestive juices, break, everything down, broken down further and small intestines Pancreas also plays a part in regulating blood sugar . the pancreas digestive juices contain enzymes that breakdown carbohydrates proteins and lipids. It also contains sodium bicarbonate which neutralizes the hydrochloric acid and the chyme that enters the intestines from the stomach.
43
Hepatic duct
from liver
44
Cystic duct
Bile enters and leaves gallbladder
45
Common bile duct
Form by union of hepatic and cystic ducts Drains bile from hepatic or cystic ducts into the duodenum (large intestines)
46
Large intestine
Contains smooth, muscle fibers contractions, produces churning, peristalsis, and defecation Lining is made of mucous membrane. Vit K and water are absorbed here. Contents move from small intestine to large intestines by way of the ileocecal valve Colon AKA large intestine starts at the right lower quadrant
47
Appendix
Is a worm like tubular structure it is attached to the back of the cecum and it is the incubator for good intestinal. Bacteria. Ithas no important digestive functions in human.
48
Enzymes
Our protein molecules that act as catalyst(cause a reaction) end with the letters ASE Amalase breakdown starches, maltase breakdown malt sugars, lactase digest lactose
49
Protein digestion
Starting in stomach and is completed in small intestine Pepin/protease start to breakdown proteins. Tripsin/protease continuous digestion of proteins Peptides- intestinal enzyme complete digestion of proteins and converts them to amino acids, which are the building blocks of life
50
The inside layer of the digestive track is
Mucosa
51
Connective tissue layer that lies beneath the lining of the digestive tract
Submucosa
52
Wall of pulp cavity
Surrounded by cementum
53
Enzyme in saliva
Amylase
54
Three divisions of the stomach are
Fondus. body. Pylorus
55
Pyloric sphincter
Holds food in the stomach
56
Length of esophagus
10 inches
57
Lower left border of stomach
Greater curvature
58
What type of gland is liver?
Exocrine gland
59
Largest gland in the body
Liver
60
Which substance does not contain enzymes?
Bio
61
Most of the digestion of carbohydrates takes place in
Small intestine
62
Fats are broken down into
Fatty acids
63
Stomach sphincter that keeps food from re-entering the esophagus
Lower esophageal, sphincter, also known as cardiac sphincter
64
Most of chemical digestion occurs
Duodenum
65
ILiocecal valve
Where undigested and unsolved food into the large intestine
66
Three. Intestinal enzymes.
Maltase. sucrase. lactase
