should help you pass, it has some stuff that MIGHT be used. - Created by Nas Ibrahim (Galvan's anatomy student)

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


Alimentary canal consists of:

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

Another name for the third molar is:

wisdom tooth

Carbohydrate absorption begins in the mouth via the enzume amylase


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


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

chyme is liquefied food found in the stomach.


controls the opening in the stomach to the small intestine?

Pyloric sphincter

The crown of the tooth is covered with:



elimination of digestible substances as feces,

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


the enzyme amylase converts which of the following?

starches to sugars

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


Enzymes that catalyze the hydrolysis of proteins are:


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


expelling feces


fat droplet surrounded by bile salts


fats are absorbed primarily into which of the following structures?

lymph in intestinal lacteals

The final produce of carbohydrate digestion is a:


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


food leaving the stomach


the function of the appendix is uncertain


gastrointestinal tract is also called

alimentary canal

the largest gland in the body is the :


the lesser omentum attaches the :

the Liver to the lesser curvature of the stomach

List the accesory organs of the digestive system:

pancreas, teeth, liver, salivary glands, gallbladder

List the functions of the digestive system

breakdown of ingested food, absorption of nutrients into the blood

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


the majority of substance are absorbed in the small intestine


Mechanical Digestion

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

the mesentery is fan-shaped projection of the parietal peritoneum



sum of all chemical reactions in the body

mixing movement


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


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


order of small intestine divisions starting proximal to the stomach

Duodeum, Jejunum, ileum


alternating waves of contraction

Peristalsis begins in the:


peristalsis can be described as a mixing movement.


The process of fat emulsficication consists of:

breaking down fats into small droplets

the process of swallowing is known as:


process of taking food into the GI tract


protein digestion begins in the:


refers to the liver



internal folds in the stomach

Salivary glands

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


moving materials back and forth to aid in mixing

The serosa is actually:

visceral peritoneum

small intestine aborption

plicae, villi, microvilli

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


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

swallowing moves a mass of food called



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

the terminal inch of the rectum is called the

anal canal

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


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

common bile duct.

The volume of saliva secreted per day is:


the volumes of stomach and duodenum are approximately equal.


where is bile stored


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

portal vein

which of the following describes the pharyngeal stage of deglutition?

oropharynx to esophagus

which one is not part of the small intestine?


Which step of deglutition is under voluntary control?
