Q. Proteins are broken down into      , while carbohydrates are broken into      .


Amino acids / fatty acids
Amino acids / sugars
Sugars / Amino acids
Sugars / fatty acids
Fatty Acids / sugars
Q. Which is not a function of the pancreas?


Break down fats with pancreatic lipase
Secrete HCO3- to neutralize chime at the small intestine
Break down proteins with pancreatic amylase
All of the above.
All are important pancreatic functions

Ascending Loop of Henle, descending Loop of Henle, vasa recta
Ascending Loop of Henle, distal tubule, vasa recta
Water, active transport of NaCl, proximal tubule
Nephron, collecting tubule, inner medulla
Ascending Loop of Henle, descending Loop of Henle, proximal tubule
Q. The Descending Loop of Henle is permeable to      , while       is permeable at the Ascending Loop.


NaCl / water
HCO3- / water
Water / NaCl
Water / HCO3-
NH3 / water
Q. Animals become constipated when:


Too little water is absorbed at the small intestine.
Too much water is absorbed at the small intestine.
Too much water is absorbed at the large intestine.
There are not enough villi in the small intestine to absorb nutrients.
An animal eats too much fiber.
Q. Protein digestion occurs in the       with the help of      .


Small intestine / pepsinogen
Small intestine / pepsin
Stomach / salivary amylase
Pancreas / salivary lipase
Stomach / pepsin
Q. Blood pressure pushes blood through the       and into the nephron's      .


Glomerulus / Bowman's capsule
Bowman's capsule / Proximal tubule
