Question 6 options: a) a cell in the hypothalamus that synthesizes peptides that are stored in the pituitary until release into the blood stream. b) a cell in the pancreas that produces enzymes that are secreted into the lumen of the digestive tract. c) a neuron in the spinal cord that receives signals from afferent neurons. d) a steroid hormone-producing cell in the adrenal cortex. e) a brain cell in the cerebral cortex that receives inputs from afferent neurons.
A researcher is studying a new species of amphibian that exhibits a high rate of nutrient absorption in its intestines. The epithelium in the intestinal lining appears to be composed of a single layer of columnar cells, and numerous tiny finger-like projections are visible on the surface of these cells. Which of the following statements best explains the role of this epithelial structure in the species' digestive system? Question 8 options: The columnar epithelium with microvilli increases the surface area for nutrient absorption, optimizing digestion efficiency. The columnar epithelium facilitates the transport of waste products from the bloodstream into the lumen of the intestine. The columnar cells produce enzymes that help digest food particles within the gut lumen. The epithelial layer forms a protective barrier against harmful pathogens by secreting mucus.
