  • increase in antidiuretic hormone levels
Q.5
Visiting high mountain main cause altitude sickness in men living in plain areas. Prime cause of this is
  • excess of \(CO_2\) in blood
  • decrease deficiency of haemoglobin
  • decreased partial pressure of oxygen
  • increased proportion of oxygen in air
Q.6
Between Breaths the intrapleural pressure is approximately …….. mm Hg less than atmospheric pressure
  • 4
  • 8
  • 1
  • 10
Q.7
Haldane effect plays an important role in promoting carbon dioxide transport than the Bohr's effect in promoting oxygen transport because
  • oxyhaemoglobin is a stronger acid which donates hydrogen ion which in turn displace carbon dioxide from blood
  • carbaminohemoglobin is a stronger acid with splits into hydrogen and bicarbonate
  • carbon dioxide is less soluble in venous blood than in arterial blood.
  • carbon dioxide reacts with water to form carbonic acid that lowers the pH in tissues
Q.8
Identify the correct statement with reference to transport of respiratory gases by blood
  • only oxygen is transported by blood
  • Hemoglobin is necessary for transport of carbon dioxide and carbonic anhydrase for transport of oxygen
  • only carbon dioxide is transported by blood
  • haemoglobin is necessary for transport of Oxygen and carbonic anhydrase for transport of carbon dioxide
Q.9
Select the incorrect statement
  • ADH decreases the reabsorption of water in the DCT and collecting duct
  • A normal adult person secretes about 1.5 litres of urine in 24 hours
  • Tubular reabsorption takes place by passive and active transport
  • Cortical nephrons control plasma volume under normal water supply
Q.10
The joint found in head of upper arm and pectoral girdle is
  • Ball and socket joint
  • Saddle joint
  • Hinge Joint
  • Gliding joint
Q.11
Intervertebral disc is found in the vertebral column of
  • mammals
  • amphibian
  • reptiles
  • birds
Q.12
Which of the following changes occur in diaphragm and intercostal muscles when expiration of air takes place
  • none of these
  • Internal intercostal muscles relax and diaphragm contracts
  • external intercostal muscles and diaphragm relax External intercostal muscles and diaphragm contract
  • Internal intercostal muscle contract and diaphragm relax
Q.13
Which of the following conditions causes filling of urinary bladder
  • Contraction of detrusor muscle of urinary bladder and relaxation of internal sphincter
  • Relaxation of detrusor muscle of urinary bladder and construction of internal sphincter
  • Construction of detrusor muscle of urinary bladder and internal sphincter
  • Relaxation of detrusor muscle of urinary bladder and internal sphincter

  • submucosa and muscularis externa
  • submucosa and mucosa
  • mucosa and muscularis externa
  • lamina propria and muscularis mucosa
Q.15
A fall in glomerular filtration rate (GFR) activates
  • posterior pituitary to release vasopressin
  • adrenal medulla to release adrenaline
  • juxtaglomerular cells to release renin
  • heart to release atrial natriuretic factor
Q.16
Cardiac activity could be moderated by the autonomous neural system. Which of the following statements is correct
  • The sympathetic system stimulates heart rate and stroke volume
  • The sympathetic system decreases the heart rate but increases stroke volume
  • The parasympathetic system stimulates heart rate and stroke volume
  • The parasympathetic system decreases the heart rate but increases stroke volume
Q.17
