Excretion of hypotonic urine in humans is associated best with the: 1.Proximal convoluted tubule 2.Glomerular capsule 3.Loop of the Henle 4.Distal convoluted tubule 2. The main difference between endotherms and ectotherms is: 1.Where from they get most of their body heat 2.Whether they are warm or cold blooded 3.How they conserve water 4.Whether they live on land or in the water 3. The water content of human blood is regulated by ADH. In which part of the nephron does regulation occur? 1.Bowmen’s Capsule 2.Descending limb of loop of Henle 3.Proximal convoluted tubule 4.Ascending limb of loop of Henle 4. A drug reduces mitochondrial activity in kidney nephrons. Which chemical will be present in increased amounts in the urine? 1.Ammonia 2.Urea 3.Glucose 4.Uric acid 5. Which of the following will cause a decrease in ADH production? 1.Dehydration 2.Abnormally low blood pressure 3.An increase in osmotic pressure of blood 4.Drinking water 6. The site and principal mechanism for the passage of glucose into the blood stream in the human kidney is the: 1.Proximal convoluted tubule, by selective reabsorption2.Glomerulus, by selective reabsorption 3.Collecting duct, by active secretion 4.Glomerulus, by ultrafiltration 7. Evidence for glomerular filtration in the kidney could be obtained by comparing the sizes of the molecules present in Bowmen’s Capsule with those in the: 1.Proximal tubule 2.Loop of Henle 3.Collecting duct 4.Afferent blood vessel 8. The walls of the ____________ are made more or less permeable to water, depending on the need to conserve water: 1.Ureter 2.Collecting duct 3.Urethra 4.Fibrous capsule 9. In man, glucose is present in blood plasma but not in urine. This is because glucose molecules are: 1.Too large to enter Bowmen’s Capsule 2.Actively transported from the proximal convoluted tubule to blood capillaries 3.Stored in the kidney 4.Oxidized to supply energy for ultra filtration 10. The function of glomerulus and Bowmen’s Capsule of the nephron is to: 1.Reabsorb slats and amino acids 2.Eliminate ammonia from the body 3.Reabsorb water into the blood 4.Filter the blood and capture the filtrate Loading...
