Before filling in your name and PeopleSoft-ID, please check that the color of your scantron sheet matches the color of your test. In column J of the scantron sheet blacken the circle corresponding to the color of your exam: white = 1; blue = 2; pink = 3; yellow = 4. Proceed with the exam, choosing the best answer for each of the following questions and blackening the proper circle on the answer sheet with a Number 2 pencil. Read each question carefully before marking the best answer on your scantron sheet.Work thoughtfully. Make educated guesses if necessary. Even wild guessing throughout should net you 20% of the total points, on the average. PLACE THE ANSWER SHEET IN ITS OWN COLOR PILE when you are done Foundations of Biology - I 3rd EXAMINATION BLUE Fall Term 07-1 - Dr. Laurel Roberts BIOSC 0150 CRN# 11790 coronary veins pulmonary artery pulmonary vein anterior & posterior vena cava pulmonary capillaries a. b. c. d. e. 1 -- This blood vessel carries the most highly oxygenated blood in the human body duodenum reticulum cecum omasum abomasum a. b. c. d. e. 2 -- X Most digestion occurs in the first 25 centimeters of the 6-meter length of the small intestine called the gastrin pepsin insulin cholecystokinin secretin a. b. c. d. e. 3 -- X The secretion of pepsinogen and HCl is controlled by the hormone the pH of the interstitial fluids will increase. plasma proteins will escape through the endothelium of the capillaries. most carbon dioxide will be carried away from tissues bound to hemoglobin. hemoglobin will not release oxygen. fluids will tend to accumulate in tissues. a. b. c. d. e. 4 -- X If, during protein starvation (kwashiorkor), the osmotic pressure on the venous side of the capillary beds drops below the hydrostatic pressure, then - we inhale. the heart rate increases. the air pressure in the alveoli increases. the volume of the thoracic cavity containing the lungs decreases. we exhale. a. b. c. d. e. 5 -- X As the diaphragm muscles begin to contract - no ATP to move cross-bridges no energy for the synthesis of actin and myosin no calcium to bind to troponin no oxygen supplied to muscle no ATP to break bonds between the thick and thin filaments a. b. c. d. e. 6 -- X When an organism dies, its muscles remain in a contracted state termed rigor mortis for a brief period of time. Which of the following most directly contributes to this phenomenon?
