|
Mouth |
receives food and is bound on the lips and the cheeks. It is the anterior opening of the digestive tract |
|
|
Tongue |
has taste bud receptors that let us experience texture and taste. composed of skeletal muscle and has a muscular exterior that helps food bolus' by mixing food with saliva |
|
|
Teeth |
Chew food into smaller pieces so it is more convenient for swallowing |
|
|
Salivary Amylase |
Sends saliva into mouth where the teeth chew food and the tongue forms it into a bolus |
|
|
Pharynx |
swallowing process occurs in the pharynx. it is the region at the back of the mouth where both food and air passageways cross |
|
|
Epiglottis |
The ventral flap of tissue on top of the trachea just interior to the larynx. It is normally opened, however reflexively closes during swallowing to allow food t go into the right passageway and not down the trachea (choke) |
|
|
Esophagus |
The muscular tube that is ordinarily collapsed but opens to receive food bolus when swallowing occurs. It is the tube that transports food from the mouth to the stomach |
|
|
Cardiac Sphincter |
A muscular constriction at the bottom of the esophagus/the top of the stomach that acts to keep food from going back up into the mouth. |
|
|
Stomach |
Thick walled, J-shaped organ that stored food and aids in digestion. It helps to mix food by "churning" it with gastric juice |
|
|
Pyloric Sphincter |
A muscular constriction at the bottom of the stomach/ the beginning of the small intestine that permits a small amount of chyme into the duodenum |
|
|
Duodenum |
The first 25 cm of the small intestine where the liver and pancreas ducts form one duct that enters into the duodenum. This is how the small intestine receives bile from the liver and pancreatic juice from the pancreas. |
|
|
Liver |
The largest gland in the body that is under the diaphragm. The liver has 2 main lobes (the smaller left lobe and the right lobe) Gatekeeper to blood- removes toxins and detoxifies and has nutrients to keep the blood constant Maintains a regular blood glucose level Produces Bile |
|
|
Gall-bladder |
Produces pancreatic juice that contains enzymes which help to digest food has an endocrine gland that secretes insulin and glucagon |
|
|
Small Intestine |
Longer than the large intestine; has a small diameter Transport- circular and longitudinal muscles to conduct peristalsis and sphincters at each end Digestion- ducts connecting small intestine to gall bladder and pancreas that deliver bile and pancreatic juice Absorption- villi are equipped with capillaries and lacteals for absorbing products of digestion |
|
|
Appendix |
no function; vestigial organ |
|
|
Large intestine (Colon) |
Digestion tube at ileo-caecum valve/sphincter 4 major sections: ascending, transverse, descending colon and rectum absorbs leftover water form the digestion process contains bacteria (E. Coli) that help form feces |
|
|
Rectum |
The last portion of the large intestine that stores feces until defecation |
|
|
Anus |
The posterior opening of the digestive tract that is protected by the anal sphincter |
