Chyme < Answer>a semiliquid mass of partially digested food that passes from the stomach into

, the small intestine


Small intestine < Answer>digestive organ in which most chemical digestion takes place majority of
digestion and absorption occur here!!


How long is the SI? < Answer>6 meters




Pyloric sphincter < Answer>circular muscle that controls the movement of chyme from the stomach
to the small intestines


Liver < Answer>large organ just above the stomach that produces bile




Gallbladder < Answer>stores bile




Bile < Answer>a mixture of salts and phospholipids that aids in the breakdown of fat




Pancreas < Answer>located partially behind the stomach in the abdomen, and it functions as both
an endocrine and exocrine gland.
It produces digestive enzymes as well as insulin and glucagon




After absorption, products of digestion goes to < Answer>blood and lymph


Villi < Answer>Small fingerlike projections on the walls of the small intestines that increase surface
area


Large intestine < Answer>colon
Organ that removes water from the undigested materials that pass through it waste moves via
peristalsis


Rectum < Answer>stores waste until egestion egestion < Answer>Removal of undigested waste


Carbohydrate (enzymes, end products and important locations) < Answer>1. Amylase, sucrase,
