organs that aid with digestion but are not part of teh digestive system. these include: the liver, gallbladder and pancreas
another way of describing the structures of the digestive system. it is broken into two sections: the upper GI tract and the lower GI tract. (gastr/o- stomach, intestin- intestinal, -al= pertaining to.)
oral cavity aka mouth
the lips, hard and soft palates, salivary glands, tongue, teeth and the periodontium
lips aka labia
form the opening to the oral cavity. the lips hold the food in the mouth and aid the tongue and cheeks in guiding food between the teeth for chewing.
the bony anterior portion of the palate that is covered with specialized mucous membrane
the flexible posterior portion of the palate. it has the imp. role of closing off the nasal passage during swallowing to prevent food and liquid from moving upward into the nasal cavity
hangs from the free edge of the soft palate. during swallowing, it moves upward with the soft palate. it also plays an imp. role in snoring and in the formation of some speech sounds.
very strong, flexible, and muscular. it aids in speech and moves food during chewing and swallowing.
upper surface of the tongue, has a tough protective covering and in some areas small bumps known as papillae.
part of the tongue, and the tissues that lie under the tongue, are covered with delicate highly vascular tissues. it is the presence of this rich blood supply under teh tongue that makes it suitable for administering certain medications by placing them sublingually where they are quickly absorbed into the bloodstream
consists of the bone and soft tissues that surround and support the teeth. (peri- surrounding, odonti- teeth, -um=noun ending)

as used in dentistry, describes any contact between the chewing surfaces of the upper and lower teeth.
makes up the bulk of the tooth structure and is protected on the outer surfaces by enamel and cementum
consists of a rich supply of blood vessels and nerves that provide nutrients and innervation to the tooth. in the crown it is located in the pulp cavity and in the roots it continues through the root canal.
a colorless liquid that moistens the mouth, begins the digestive process, and lubricates food during chewing and swallowing.
secrete saliva that is carried by ducts into the mouth. they consists of three pairs: parotid glands, sublingual glands, submandibular glands
located on the face in front and slightly lower that each ear. the ducts for these glands are on the inside of the cheek near the upper molars
a lid like structure that closes off the entrance to the trachea(windpipe) to prevent food and liquids from moving from the pharynx during swallowing.
lower esophageal sphincter aka cardiac sphincter aka gastroesophageal sphincter
a muscular ring that controls the flow between the esophagus and stomach. the sphincter normally opens to allow the flow of food into the stomach and closes to prevent the stomach contents from regurgitating into the esophagus.
a sac-like organ composed of the fundus (upper, rounded part), body (main portion), antrum (lower part)
are the folds in the mucosa lining the stomach. glands located within these folds produce gastric juices that aid in digestion and mucus to create a protective coating on the lining of the stomach
the ring like muscle that controls the flow from the stomach to the duodenum of the small intestine
extends from the pyloric sphincter to the first part of the large intestine. the small intestine is a coiled organ up to 20 feet in length. the small intestine consists of three sections (duodenum, jejunum, ileum) where food is digested and the nutrients are absorbed into the blood stream
the frist portion of the small intestine. the duodenum extends from the pylorus to the jejunum
the last and longest portion of the small intestine, it extends fro the jejunum to the cecum of the large intestine
extends from teh end of the small intestine to the anus. it is about twice as wide as teh small intestine but only one-fourth as long. it is here that the waste products of digestion are processed in preparation for excretion through the anus. the major part of the large intestine are the cecum, colon, rectum and anus
a pouch that lies on the right side of the abdomen. it extends from the end of the ileum to the beginning of the colon
the ring like muscle that controls the flow from the ileum of the small intestine into the cecum of the large intestine
vermiform appendix aka appendix
hangs from the lower portion of the cecum. it consists of lymphoid tissue.
the longest portion of the large intestine is subdivided into four parts: ascending colon, transverse colon, descending colon, sigmoid colon.
an S-shaped structure that continues from the descending colon above and joins with the rectum below.
the widest division of the large intestine, makes up the last 4 inches of the large intestine and ends at the anus
the lower opening of the digestive tract. the flow of wast through the anus is controlled by the internal anal sphincter and the external anal sphincter
refers to the anus and rectum as a single unit. (an/o- anus, rect-rectum, -al=pertaining to)
accessory digestive organs
play key roles in digestion but are not a part of the gastrointestinal tract. they are: the liver, the biliary tree, the gallbladder, the pancreas
a large organ located in the right upper quadrant of the abdomen. it has several important functions related to removing toxins from the blood and turning food into the fuel and nutrients the body needs.
functions of the liver
1) it removes excess glucose(blood sugar) from the bloodstream and stores it as glycogen (a form of starch). when the blood sugar level is low it converts it back into glucose for release. 2) liver also destroys old erythrocytes, removes toxins from the blood stream, and manufactures some blood protein. 3) secretes bile which aids in the digestion of fats. it travels from the liver to the gallbladder where it is concentrated and stored.
the pigment produced from the destruction of hemoglobin, is released by the liver in bile.
provides the channels through which the bile is transported from the liver to the small intestine
functions of the biliary tree
1) small ducts in the liver join together like branches to form the biliary tree. the trunk, which is just outside the liver is known as the common hepatic duct. 2) the bile travels from teh locer through the common hepatic duct to the gallbladder where it enters and exits through the narrow cyst duct. 3) the cyst duct leaving the gallbladder rejoins the common hepatic duct to form the common bile duct. the common bile duct joins the pancreatic duct and together they enter the duodenum of the small intestine.
a pear-shaped organ about the size of an egg located under the liver. it stores and concentrates the bole for later use. when bile is needed the gallbladder contracts forcing the bile out through the biliary tree
a soft 6 inch long oblong gland that is located behind the stomach. the gland has important roles in the digestive and endocrine systems.
digestive functions of the pancreas
1) produces and secretes pancreatic juices that aid in digestion and contain sodium bicarbonate to help neutralize stomach acids and digestive enzymes. the pancreatic juices leave the pancreas through th pancreatic duct that joins the common bile duct jsut before the entrance into the duodenum
the process by which complex foods are broken down into nutrients in a form the body can use.
responsible for the chemical changes that break foods down into simpler forms of nutrients for use by the body.
a substance (usu from food) that is necessary for normal functioning of the body. primary nutrients include: carbs, fats and proteins. essential nutrients includ: vitamins and minerals.
includes all process involved in the body's use of nutrients. it consists of two parts: anabolism and catabolism. (metabol- change, -ism=condition)
the process by which completely digested nutrients are transported to the cells throughout the body
finger-like projections that covers the mucosa that lines the small intestines and contains blood vessels and lacteals. the blood vessels absorb nutrients directly from the digestive system into the bloodsream for delivery to the cells of the body.
specialized structures of the lymphatic system that absorb fats and fat soluble vitamins (that can not be transported directly by the bloodstream) and transports them via the lymphatic system. as they are transported they are filtered by the lymph nodes in prep for their delivery to the bloodstream
mastication aka chewing
breaks food down into smaller pieces, mixes it with saliva and preps it to be swallowed.
a mass of food tht has been chewed and is ready to be swallowed. the term bolus is also used in relation to the admin of medication
a series of wave-like contractions of the smooth muscles in a single direction. in the esophagus, food moves downward through the action of gravity and peristalsis.
the stomach contains hydrochloric acid and digestive enzymes to begin the digestive process. few nutrients enter the bloodstream through the walls of the stomach
a semifluid mass of partly digested food that passes out of the stomach through the pyloric sphincter and into the small intestine. (the churning action of the stomach works with teh gastric juices by converting the food into chyme)
role of the small intestine
the conversion of food into usable nutrients is completed as the chyme is moved through the small intestine by peristaltic action. in the duodenum, chyme is mixed with pancreatic juice and bile. the bile breaks apart large fat globules so enzymes in the pancreatic juices can digest the fats. the jejunum secretes large amount of digestive enzymes and continues the process of digestion. the primary function of the ileum is the absorption of nutrients from the digested food.
the breaking apart of large fat globules so enzymes in the pancreatic juices can digest the fats. it must be completed before the nutrients can be absorbed onto the body.
role of the large intestine
to receive the waste products of digestion and store them until they are eliminated from the body. food waste enters the large intestine in liquid form. excess water is reabsorbed into the body through the walls of the lrg intest, helping to maintain the bodys fluid balance and remaining waste forms into feces.
the rumbling noise caused by the movement of gas in the intestine. this gas is produced by the millions of bacteria which help break down organic waste material in the large intestine
