ANAT 100 EXAM QUESTIONS AND
CORRECT ANSWERS!!
What are the components of the digestive tract
mouth, oral cavity, pharynx, esophagus, stomach, small intestine, large intestine, and anus
what are the components of the digestive accessory organs
tongue, teeth, salivary glands, liver, biliary ducts and gallbladder, and pancreas
Digestive system groups (2)
The digestive tract (alimentary canal)
The accessory digestive organs
Digestion
process of masstication into smaller pieces to faciliate chemical processing by enzymes
Absorption
digested food moves slowly through the large intestine to faciliate water and nutrient uptake
Secretion
cells of the stomach's mucosal wall release gastric acid to perform chemical digestion
Motility
when food is swallowed muscles in the esophageal wall contract and relax to push food through
esophagus down to the stomach
Elimination of waste
leftover materials are eliminated by the process of defecation
Mucosa
innermost layer of the digestive tract
, What makes up the mucosa of the digestive tract wall (3)
- surface epithelium for secretion absorption and protection
- lamina propria, the loose connective tissue
- muscularis mucosa of smooth muscle fibres
Describe the submucosa of the digestive tract wall
dense irregular connective tissue containing blood vessels, lymphatics, glands, and nerve
plexuses
What is the muscularis externa of the digestive tract wall
circular and longitudinal layers of smooth muscle with nerve plexuses between the layers
plexuses help contract to propel food forward
What is the serosa/adventitia of the digestive tract wall
outmost layer sometimes a single layer of thin cells and sometimes loose connective tissue
serous membrane--> serosa
loose CT --> adventitia
histology of digestive tract overview
MUCOSA --> SUBMUCOSA --> MUSCULARIES EXTERNA --> SEROSA OR
ADVENTITIA
What is the start of the digestive tract (6)
the oral cavity
(palate, tongue, salivary glands, teeth, pharynx, and tonsils)
the oral cavity parts (2)
