|

|
|
The _______________ is a posterior continuation of the nasal cavity and is not actually part of the digestive system.
|
nasopharynx

|
The _________ is a small, fleshy mass which hangs from the soft ________, just above the base of the tongue.
|
uvula
palate |
|
The _______________ which is a combination of the roots oro- (meaning relationship to the mouth) and pharynx, extends from the soft palate within the mouth to the level of the hyoid bone. Also in this region is the ____________, which is a lid-like structure composed of cartilage which hangs over the entrance to the larynx to prevent food from entering the larynx or trachea upon swallowing.
|
oropharynx
epiglottis |
|
The _____________ is that part of the alimentary canal which connects the pharynx to the stomach. It is basically a muscular tube which is about 25 cm long. The muscular function of the ____________ is not voluntary. There are basically eight steps which occur to get food from the mouth to the stomach.

esophagus

rounded mass of food
|
bolus
|
|
What is the most distended portion of the alimentary canal?
|
stomach
|
|
The _________ orifice is the junction between the esophagus and the stomach. This is also frequently referred to as the "GE junction" (gastroesophageal junction).
|
cardiac
|
|
The _________ is the dome-shaped portion of the stomach which extends slightly above the cardia orifice.
|
fundus
|
|
The _______ of the stomach is the widest portion and is located between the lesser and greater curvatures.
|
body
|
|
The ___________ of the stomach is the last area of the stomach, just before the duodenum.
|
pylorus
|
|
The _____________ ________________ is the longest portion of the alimentary canal.
|
small intestine 21 feet long and is 2.5 cm wide
|
|
The small intestine is divided into three main regions which are:
|
1. duodenum
2. jejunum 3. ileum |
|
The small intestine makes the transition to the large intestine here through what is called the ___________ ___________.
|
ileocecal valve
|
|
The distal-most portion of the alimentary canal is the __________
__________________. |
large intestine
|
|
Most water is absorbed and feces are formed in the __________ ____________.
|
large intestine
|
|
The large intestine is divided into four major regions: List them
|
1. cecum
2. colon 3. rectum 4. anal canal/anus |
|
The cecum opens into the colon and has the ___________, a small, finger-like projection, which is attached to its medial portion.
|
appendix
|
|
The second portion of the large intestine is the colon. Different areas of the colon have specific terms assigned to them. First is the Q#1______________ colon which arises from the cecum and goes in an upward direction (ascends). At approximately the liver the colon bends sharply, and this area is referred to as the Q#2_____________ flexure. The colon then extends in a horizontal direction, and that portion is called the Q#3___________ colon. At the left abdominal wall there is another sharp bend in the colon. This is called the Q#4____________ flexure and is the beginning of the Q#5____________ colon, or that portion of the large intestine which goes downward (descends). Finally, the colon terminates in an S-shaped bend which is referred to as the Q#6___________ colon.
|
1. ascending
2. hepatic 3. tranverse 4. splenic 5. descending 6. sigmoid |
|
The next of the four major regions of the large intestine is the rectum, which is a tube approximately 15 cm long which is located between the sigmoid colon and the ______ canal. The _______ canal forms a muscular opening in the muscles of the pelvic floor which is called the _______. This is currounded by both involuntary and voluntary muscular ___________.
|
anal
anal anus sphincters |
|
The large intestine is so named because it is the ____________ portion of the canal(6 cm in diameter).
|
widest
|
|
The large intestine has a larger ______________ than the small intestine.
|
diameter
|
|
There are no _________ in the large intestine.
|
villi
|
|
There are three distinct longitudinal muscles, ________ coli, which run the length of the large intestine.
|
teniae
|
|
There is also a series of bulges in the wall of the large intestine which are called ________________ or haustra.
|
sacculations
|
|
Although the alimentary canal comprises most of the digestive system, there are a few accessory organs which secrete directly into the alimentary canal via ducts, and these are therefore important to digestion. They include the liver, _____________, and the pancreas.
|
gallbladder
|
|
The liver is the largest ________ in the body.
|
gland
|
|
The ________ is made up of many liver lobules which produce bile which is continuously secreted into the intestines and is very important to digestion.
|
liver
|
|
The ________________ is a sac-like organ which is attached to the undersurface of the liver. It stores and concentrates bile.
|
gallbladder
|
|
The _______ duct drains the gallbladder. It unites with the ___________ duct to form the ___________ _______ which conveys bile into the duodenum.
|
cystic
hepatic common bile |
|
The pancreas is involved in both the digestive and the ____________________ systems. For its role in digestion, it creates __________ and secretes them into the duodenum for the breakdown of foods.
