List the functions of the digestive system

breakdown of ingested food, absorption of nutrients into the blood

Alimentary canal consists of:

mouth, phaynx, esophagus, stomach, small intestines, large intestines, anus

List the accesory organs of the digestive system:

pancreas, teeth, liver, salivary glands, gallbladder

Starting from the deepest layer and moving towards the most superficial, the layers of the wall of the GI tract are:

mucosa, submucosa, muscularis, serosa

The serosa is actually:

visceral peritoneum

gastrointestinal tract is also called

alimentary canal

The crown of the tooth is covered with:


swallowing moves a mass of food called


controls the opening in the stomach to the small intestine?

Pyloric sphincter

order of small intestine divisions starting proximal to the stomach

Duodeum, Jejunum, ileum

Carbohydrate absorption begins in the mouth via the enzume amylase



internal folds in the stomach


food enters at the cardioesophageal sphincter,
acts as a storage tank for food,
delivers chime (processed food) to the small intestine

Salivary glands

Saliva-producing glands
Parotid glands- anterior to the ears
submandibular glands
sublingual glands


the role is to masticate food, humans have 2 sets of teeth, decidous and adult with 32 teeth ( ages 6-12 years), incisors, canines, premolars, molars


alternating waves of contraction


moving materials back and forth to aid in mixing

Mechanical Digestion

mixing of food in the mouth by the tongue, churning food in the stomach, segmentation in the small intestine

Chemical Digestion

enzymes break down food materials into their building blocks carbohydrates broken into simple sugars
protein broken into amino acids
fats broken into fatty acids


elimination of digestible substances as feces,


sum of all chemical reactions in the body

the tissue layers of the GI tract are constant, with no variation in the different organs.


the folds in the lining of the stomach are called rugae.


the cardiac sphincter controls the opening of the esophagus into the stomach.


small intestine aborption

plicae, villi, microvilli

the terminal inch of the rectum is called the

anal canal

the lesser omentum attaches the :

the Liver to the lesser curvature of the stomach

the liver consists of two lobes separated by the falciform ligament.


where is bile stored


refers to the liver


The volume of saliva secreted per day is:


Another name for the third molar is:

wisdom tooth

after food has been chewed, it is formed into a small founded mass called a:


the largest gland in the body is the :


the function of the appendix is uncertain


the esophagus is voluntary in the upper third, mixed in the middle, and involuntary in the lower third.


the mesentery is fan-shaped projection of the parietal peritoneum


which of the following describes the pharyngeal stage of deglutition?

oropharynx to esophagus

Which step of deglutition is under voluntary control?


The final produce of carbohydrate digestion is a:


Enzymes that catalyze the hydrolysis of proteins are:


The process of fat emulsficication consists of:

breaking down fats into small droplets

peristalsis can be described as a mixing movement.


the volumes of stomach and duodenum are approximately equal.


olfactory and visual stimuli are factors concerning the control of digestive gland secretion


chyme is liquefied food found in the stomach.


fats are absorbed primarily into which of the following structures?

lymph in intestinal lacteals

movement of lower colon and rectum contents at a rate slower than normal can cause:


which blood vessel carries absorbed nutrients from the GI tact to the liver?

portal vein

the majority of substance are absorbed in the small intestine


process of taking food into the GI tract


food leaving the stomach


mixing movement


expelling feces


fat droplet surrounded by bile salts


during the process of digestion, stored bile is poured into the duodenum by which of the flowing?


protein digestion begins in the:


the enzyme pepsin is concerned primarily with the difgestion of which of the following?


the enzyme amylase converts which of the following?

starches to sugars

which one is not part of the small intestine?


The union of the cystic duct and hepatic duct from the :

common bile duct.

the process of swallowing is known as:


Peristalsis begins in the:
