What is epiglottis? Importance?
A flap in the throat that covers the trachea to prevent food from getting in.
Define peristalsis.
rhythmic muscular contraction to push the food further down the digestive tract
What is the function of the large intestine.
absorb water from chyme and form feces.
Why does pepsin function in the stomach but not in the small intestine?
it needs an acidic environment to work.
This is the thing that makes your Bio teacher instantly happy before the lesson begins?
students showing up on time β°
Mention the two types of digestions that take place in the stomach and explain how does each of them occur.
mechanical : when the stomach smashed food.
Chemical: when enzymes + HCL break down food.
What is bile? Function.
yellow- green substance made in the liver and stored in the gallbladder to digest fat.
What is the function of pepsin enzyme? Where is it found?
enzyme that digests proteins
in the stomach
If amylase were absent, which macromolecule digestion would be most affected?
Carbohydrates
What student habit upsets your Bio teacher during the class?
sidetalks π£οΈπ£οΈπ£οΈπ£οΈ
Mention two events that take place in the small intestine.
1. Enzymes sent from pancreas break down : fats, carbs, & proteins.
2. Nutrients are absorbed through villi.
What are gallstones?
cholesterol crystals that form in the gallbladder and cause inflammation
Glands that make saliva.
under the lower jaw
under the tongue
near the ear
Predict the effect on digestion if peristalsis stopped but enzymes were normal.
food wouldn't move β
digestion incomplete β
nutrients absorption fails.
If the your Bio teacher could bring a pet to class, what would it be?
Monkey π
True or False: fix if false
food passes through the pancreas just before reaching the stomach to get some digestive enzymes.
false, food does not pass through the pancreas.
Define mucus. What specific problem would occur without it?
thick coating that covers the stomach & protect it from HCL.
The stomach would digest itself by HCL and pepsin.
Define villi and mention their function + location.
finger-like projections in the small intestine that absorb nutrients.
Located in the large intestine, these produce certain vitamins like vitamin K & B.
Good Bacteria

What are the two gates that closes the stomach from top and bottom?
top: cardiac sphincter.
bottom: pyloric sphincter
Which type of weather does your Bio teacher secretly love teaching in?
