Dopamine Norepinephrine Epinephrine Acetylcholine None 11. If villi in the small intestine were to become damaged, which of the following would likely occur? A reduced ability to breakdown fat due to the inability of villi to secrete bile. Segmentation of the stomach would be negatively affected leading to reduced digestion. Malnutrition would result due to a decreased ability to absorb nutrients. Gastric reflux disease would result due to the increased production of stomach acid. None 12. Which of the following statements is true about protein digestion? The majority of protein absorption occurs in the large intestine. The majority of mechanical protein digestion occurs in the stomach. Chemical digestion of protein initially occurs in the mouth. Absorption of protein occurs primarily in the small intestine. None 13. Which of the following best describes the mechanical process of normal breathing during expiration? The diaphragm relaxes and moves upward, while the intercostal muscles contract and move the ribs upward. The diaphragm contracts and moves upward, while the intercostal muscles relax and contract upward. The diaphragm relaxes and moves downward, while the intercostal muscles relax and move the ribs downward. The diaphragm relaxes and moves upward, while the intercostal muscles relax and move the ribs downward. None 14. Which of the following is not a function of the integumentary system? facilitate absorption of lipid-soluble materials including fat-soluble vitamins function in immunity as part of the adaptive immune system provide a large surface area for excretion of metabolic wastes facilitate thermoregulation by constantly allowing water to leave through the epidermis None 15. Which of the following hormones is responsible for increasing calcium levels in the blood by stimulating bone resorption? Parathyroid hormone Insulin Luteinizing hormone Thyroid hormone None 16. Which of the following is true about hormones? Excessive production of cortisol in the adrenal glands can lead to low levels of sodium in the blood. Lack or insufficiency of insulin produced by the pancreas can lead to diabetes. Overproduction of growth hormone can lead to dwarfism. Failure of the pituitary gland to produce thyroid-stimulating hormone can result in hyperthyroidism. None 17. Gastric reflux occurs as a result of an improper closing of the ________________.

Which of the following organelles is more likely to be predominant in osteoblasts? Ribosomes Lysosomes Mitochondria Nucleus None 22. Which of the following comparisons between arteries and veins is true? Veins have valves, and arteries do not. Veins have thick, muscular walls, while arteries have thin, more compliant walls. Veins have a smaller diameter than arteries. Veins carry freshly oxygenated blood from tissue back to the heart, while arteries carry oxygen-depleted blood away from the heart. None 23.
