hows the respiratory system regulate pH? bicarbonate buffer: when pH is too low, acid sensing receptors send signal to increase respiratory rate: pushes buffer system to the left, causing the H+ ion level to drop (be less acidic) 126. how to break disulfide bonds add strong acid to protonate the thiol groups 127. How to tell a single, double, and triple crossover single will have a switch with one middle and the adjacent flanking alleles, double will have two middle alleles right next to each other, and triple is with one flanking and one middle that is not adjacent 128. how would renin secretion respond to a large influx of isotonic solution increasing fluid would increase arterial pressure, thereby decreasing renin secretion, and then decreasing aldosterone, leading to less Na and H20 reabsoption 129. a human epithelial cell is undergoing mitosis, during DNA how much genetic material is there during anaphase two sets, each set consisting of 46 chromosomes each and distinct being pulled to each side 130. hypophyseal portal system a blood vessel system that directly connects the hypothalamus with the anterior pituitary 131. hypothalamus the bridge between nervous and endocrine systems by regulating the pituitary gland with tropic hormones 132. increased amounts of T3 and T4 lead to increased cellular respiration, greater amount of protein and fatty acid turnover

133. In terms of being open or closed, what is the state of the mitral and tricuspid valves (left and right atrioventricular valves, respectively) at the end of the first heart sound? both are closed 134. In the circulatory system, how do cross section of the tube and velocity of blood flowing through relate and why? they are inversely proportional, because together the product of the two makes flow rate. There must be a constant flow rate because the same amount of volume must be flowing at the same time 135. the intraplural pressure is necessarily lower than the atmospheric pressure during inhalation, because the expansion of the chest cavity causes compression of the intrapleural space, decreasing its pressure 136. lacteal small lymphatic vessel that runs in the center of the villi in the small intestine; site of lipid absorption into the lymphatic system 137. Lateral geniculate nucleus relay center in the thalamus for the visual pathway (info from retina) 138. leukocyte v granulocytes v lymphocytes leukocytes: white blood cells granulocytes: eat microbes lymphocytes: specific immune response (B cells and T cells) 139. low and high blood pressure promotes which hormones low: aldosterone and ADH high: ANP 140. major component of bile bilirubin, which is a byproduct of the breakdown of hemoglobin 141. major functions of the proximal tubule, loop of henle, proximal tubule, and collecting duct proximal tubule: protein secretion and absorption loop of henle: exchange with the vasa recta and the adjustment of solute amounts in urine distal tubule: concentration of urine before excretion, adjustment of some ions in regulation of acid-base balance (bicarbonate buffer system) collecting duct: concentration of urine before excretion 142.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
