VERIFIED QUESTIONS WITH DETAILED
SOLUTIONS GRADED A+
⩥ Peristalsis.
Answer: -mechanical aspect
-as the circular and longitudinal muscles tighten and relax, the food
moves ahead of the constriction. Seen in the esophagus, stomach, and
small intestine
-wavelike muscular squeezing of the esophagus, stomach & small
intestine that pushes their contents along
⩥ villi & microvilli.
Answer: -in small intestine
-helps with absorption of nutrients which are then transported to the
body's cells
-products of carbs and proteins are transported to the liver
⩥ storage of nutrients.
Answer: -carbohydrates: LIMITED storage capacity (glycogen)
-proteins: NOT stored (stored as fat)
,-Fats: UNLIMITED storage capacity: all excess macronutrients (carb
and protein) are stored as fat
-vitamins and minerals: some can be stored
⩥ chemical aspects.
Answer: mouth
stomach
small intestine
⩥ microbiota.
Answer: -digestive tract bacteria
-mix of microbial species of a community
-breaks down remnants of food (food not digested in small intestine) in
the colon
-harvest energy from undigested food substances and use it to sustain
themselves
⩥ Possible Health benefits of alcohol.
Answer: -reduced risks of heart attacks, strokes, diabetes
-improved blood lipids, blood clotting factors
-mental acuity
-EPIDEMIOLOGIC - CORRELATIONS ONLY
, ⩥ Negative effects of alcohol.
Answer: -Interferes with nutrient absorption and is a psychoactive drug.
-DISPLACES food intake
-Heart disease, cancer, diabetes, fatty liver and liver disease, excess
energy- obesity, increase nutrient needs, interferes with metabolism,
accidents, violence
-Upon exposure to alcohol, the liver speeds up its synthesis of fatty acids
(fatty liver= cirrhosis)
⩥ fructose.
Answer: -fruit sugar
-monosaccharide
-made by rearranging atoms n glucose molecules
-most consumed in sweet beverages, desserts, and other foods
⩥ glucose.
Answer: -single sugar used in both plant animal tissues for energy
-sometimes known as blood sugar
-starch, glycogen, cellulose
⩥ cellulose.
Answer: fiber
