Question
37. In NIDDM.(non insulin dependent diabetes mellitus) the patient is usually over forty, overweight and has normal or slightly elevated levels of A) glucocorticoids B) glucagon C) insulin D) somatostatin E) thyroid hormone 38. Glucose in the urine (glucosuria) may be an indication of A) Diabetes Insipidus B) Hyperglycemia C) Hypertension D) Glomerulonephritis E) Hypothalmic dysfunction 39. Which structure contains the lowest amount of oxygen? A) pulmonary vein B) right coronary artery C) continuous capillaries D) right atrium E) jugular artery 40. The hormone gastrin: A Is secreted by the pancreatic islets. B Increases the activity of parietal and chief cells. C Is produced in response to sympathetic stimulation. D Inhibits the activity of the muscularis of the stomach. E none of the above 41. Highly oxygenated blood enters the heart through theand is pumped out the A) pulmonary arteries; left ventricle B) left atrium; aorta C) right ventricle; pulmonary trunk D) right atrium; aorta E) jugular vein; ventriclesExplanation / Answer
Ans. 37.
The choice is (C). INSULIN.
In the early stages of NIDDM insulin levels are normal or slightly elevated but in the late stage of NIDDM insulin levels decline.
Ans.38.
The choice is (B). HYPERGLYCEMIA.
Glycosuria happens because of abnormal high levels of glucose in the blood (Hyperglycemia). When Renal tubules of kidney are not able to reabsorb all the glucose then the glucose is excreted in urine.
Ans.39.
The choice is (D). RIGHT ATRIUM.
Right atrium receives deoxygenated blood from superior and inferior venacava and hence it contains the lowest amount of oxygen.
Ans.40.
The choice is (B). INCREASES THE ACTIVITY OF PARIETAL AND CHIEF CELLS.
Gastrin is produced by G cells and stimulates parietal cells to secrete acid and chief cells to secrete pepsinogen.
Ans.41.
The choice is (B). LEFT ATRIUM, AORTA.
Highly oxygenated blood enters Left atrium when oxygenated blood from lungs comes to left atrium by pulmonary vein. From left atrium the oxygen rich blood enters Left ventricle and then left ventricle pumps blood out to the entire body through Aorta.
