BIOS256: EDAPT WEEK 1 TEST
QUESTIONS WITH VERIFIED
SOLUTIONS
digestion begins in the - mouth
ingestion - - the selective intake of food
secretion - - the introduction of enzymes and other glandular products
motility - - the movement of food and mixing it with secretions
digestion - - the mechanical and chemical breakdown of food into a usable form
absorption - - the uptake of nutrient molecules and water into the cells of the digestive
tract and ultimately into the blood or lymph
compaction/defecation - - the consolidation of indigestible residue and its elimination in
the form of feces
muscularis externa - - the layer of the GI tract containing two bands of smooth muscle
submucosa - - the layer of the GI tract that is composed of blood and lymphatic vessels,
as well as nerves
mucosa - - the epithelial lining of the GI tract

serosa - - the outermost layer of the GI tract
segmentation - - the muscle movement that ultimately increases surface area of nutrients
in the small intestine
- movements within the small intestine to slow the movement of its contents
mass movement - - a strong peristalsis that only occurs in the large intestine
- powerful contractions that propels material forward
haustral churning - - the type of segmentation that occurs in the large intestine
- slow segmental movements in large intestine
peristalsis - - the type of movement which results in the propulsion of nutrients through
the GI tract
- weak, ripple-like
place the following steps of digestion in correct order that they occur
- absorption in the small intestine
- conversion of waste products into feces
- the formation of a bolus
- the formation of chyme - - the formation of bolus
- the formation of chyme
- the absorption in the small intestine
- conversion of waste products into feces
