BIO 202. Lecture Quiz 3
Epithelial membranes are generally very thin with high surface area because - answer
Exchange of fluids, ions, gasses, etc. occurs across these layers of epithelial cells
The direction of blood flow in fish gills is opposite the direction of water flow past the
gills. Which of the following should be expected if this structural relationship represents
a countercurrent exchange mechanism for oxygen - answerNet movement of oxygen
from water into blood occurs along the entire distance where blood and water are in
close contact.
The digestion of proteins begins in the - answer Stomach
Because of the hepatic portal vein system, the first organ to receive most of the
products of digestion from the intestines - answerLiver
Which of the following animals as a bulk feeding life history? - answerSnake
Most digestion in humans occurs in the first 25cm of the small intestine called the -
answerDuodenum
Within endotherms, the relationship between body size and metabolic rate is not linear
because - answerLarge endothermic animals have lower surface area to volume ratios,
meaning they can more easily maintain a constant body temperature compared to small
animals
The major macronutrients needed by animals include - answerCarbohydrates, proteins,
fats
In horses, rodents, and lagomorphs (all hindgut fermenters) the digestion of plant
material (i.g., cellulose) occurs through the action of symbiotic bacteria (and other
microorganisms) housed in the - answerCecum
The vertebrate digestive system consists of - answerA one-way alimentary canal with a
separate mouth and anus, plus accessory organs
Organisms that feed primarily or exclusively on the blood of other animals would be
classified as - answerCarnivores
In humans, the absorptive surface area of the small intestine is approximately equal to -
answerA tennis court
