Chapter 8 Digestive System Flashcards
abdomen
portion of the body between the thorax and the pelvis
anus
sphincter muscle (ringlike band of muscle fiber that keeps an opening tight) at the end of the digestive tract, connected to the rectum
appendix
small, wormlike pouch attached to the cecum (the beginning of the large intestine)
colon
major component of the large intestine, which is divided into four parts; ascending colon, transverse colon, descending colon, and sigmoid colon
esophagus
tube that transports food from the pharynx to the stomach
gallbladder
small, saclike structure that stores bile produced by the liver
gums
pale pink tissue that is attached to jaw bones and teeth; provides supporting structure for the mouth
large intestine
approximately 5 foot canal extending from the ileum to the anus
liver
organ that produces bile for the digestion of fats; performs many other functions that support digestion and metabolism
mouth
opening through which food passes into the body; breaks food into small particles by mastication (chewing) and mixing with saliva; (also called the oral cavity)
pancreas
organ that secretes multiple enzymes necessary for digestion; also secretes insulin for carbohydrate metabolism
pharynx
performs swallowing action that passes food from the mouth into the esophagus
rectum
last part of the large intestine connecting to the anus
sigmoid colon
S-shaped section of the large intestine leading into the rectum
small intestine
20-foot tube extending from the stomach to the large intestine, where most of the nutrients are absorbed; has three sections; duodenum, jejunum, ileum
stomach
J-shaped sac that mixes and stores food; secretes substances that aid digestion
tongue
organ in mouth composed of skeletal muscle; responsible for movement of food from mouth to pharynx, and is also important for taste and speech
