1. Release of neurotransmitter from presynaptic vesicles is an example of Facilitated diffusion Active transport Simple diffusion Exocytosis 2. A decrease in which of the following parameters would tend to increase the glomerular capillary hydrostatic pressure? Efferent arteriolar resistance Capillary filtration coefficient Bowman’s capsular hydrostatic pressure Afferent arteriolar resistance 3. With time, blood stored in a blood bank tends to become relatively depleted of 2,3- diphosphoglycerate (2,3-DPG). What effect does this have on the hemoglobin-oxygen dissociation curve? Shifts the curve to the left, so that the hemoglobin has a decreased oxygen affinity Shifts the curve to the left so that the hemoglobin has an increased oxygen affinity Shifts the curve to the right, so that the hemoglobin has a decreased oxygen affinity Shifts the curve to the right, so that the hemoglobin has an increased oxygen affinity 4. Hypoxia due to slowing of circulation is None Stagnant Histotoxic Anemic 5. fetal hemoglobin has higher affinity for oxygen due to reduced pH increased release of carbondioxide decreased 2,3 DPG concentration oxygendissociation curve is shifted to right 6.

Which of the following can be determined by calculation of the clearance of paraaminohippuric acid (PAH)? Glomerular filtration rate (GFR) Plasma volume Effective renal plasma flow (ERPF) Extracellular fluid (ECF) volume 14. C ‘wave in JVP is due to Atrial filling with tricuspid valves closed Atrial contraction Bulging of tricuspid valve into the right atrium Rapid right ventricular filling 15. Increasing urine flow rate from 1 mL/min to 10 mL/min will significantly increase the clearance of creatinine urea inulin penicillin 16. which of the following is absorbed in stomach amino acids salts alcohols fatty acids 17. in a normal person which of the following occurs when he becomes supine from a standing position heart rate increases and settles to a higher level there is an immediate increase in venous return decreased perfusion at the apex of lung cerebral blood flow increases 18. Countercurrent mechanism in the kidney is responsible for Absorption of glucose Osmotic gradient in medulla Maintenance of blood flow Secretion of uric acid 19. Peristalsis of ureter depends on Sympathetic flow Sympathetic and parasympathetic flow Pacemaker in smooth muscle of renal calyces parasympathetic flow 20.
