when passing stools.
lactose intolerance: - correct answer ✅The inability to completely digest
the milk sugar lactose, but most individuals with this condition can tolerate
dairy in small amounts
diabetes - correct answer ✅a disease caused by hormone imbalance. There are
2 types: Type 1 and Type 2. In both cases the blood sugar levels are high and
there is a lack of insulin.
Digestion - correct answer ✅process of transforming food into basic nutrients
that can be absorbed and used by the body
Enzymes, acid, bile, and mucus - correct answer ✅chemical means the body has
at its disposal to further aid in breaking down food
, Without the process, the nutrients we initially consume in food would be
useless: - correct answer ✅digestion
Before food even enters the mouth, a cascade of events involving the nervous
system and a variety of hormones are set off based on a variety of stimulus: -
correct answer ✅cognition, sound, odor, appearance, and taste

, taste - correct answer ✅begins as the food enters your mouth and also how it
feels
Once food enters the mouth it begins to break down into smaller units in both -
correct answer ✅mechanical and chemical processes
Mechanical process begins - correct answer ✅in the mouth with chewing
peristalsis - correct answer ✅involuntary muscle contractions are used to move
food mixtures along the tract
enzymes - correct answer ✅proteins that catalyze (speed up) chemical
reactions. They catalyze the chemical reactions required to break down food
particles into smaller parts, which prepares the nutrients for absorption
gastrointestinal (GI) tract - correct answer ✅a long hollow tube consisting of
several layers of tissue that begins with the mouth and ends at the anus

, nutrient absorption occurs across the wall of the - correct answer
✅gastrointestinal (GI) tract
mucosa (intestinal wall) - correct answer ✅is the inner-most layer, and it is
made of absorption cells and glands
circular and longitudinal muscles - correct answer ✅comprise the outer layers,
both of which function to mix and move food along the GI tract
Circular bands of muscle - correct answer ✅most often found where one part
of the tract connects to another, serving as valves to control the flow of the
food particles
3 processes the body can use to move nutrients from the GI tract into the
blood/lymph system and eventually into the cells: - correct answer ✅Passive
diffusion, Facilitated diffusion, and Active transport
Passive diffusion - correct answer ✅substances move easily in and out of cells
without the use of energy. Nutrients move from high to low concentration.
