Lungs || pleura || 5 steps OF respiration || breathing inhalation and exhalation || pulmonary volume and capacity || exchange OF gases at alveolar and tissue surface

which of the following statements are correct . ? (i) Fishes respire with the lungs . (ii) A water breather expends much nore energy in ventilating its respiratory surface than an air- breathing one. (iii) Lungs become empty after forceful expiration. (iv) A rise in Po_(2) increase the affinity of haemoglobin for oxygen. (v ) Lactic acid is produced in anaerobic respriation . (vi) Exchange of gases in the lungs is interrupted during expiration. (vii) A molecule of haemoglobin can carry 1-4 molecules of oxygen. (viii) maximum contraction of diaphragm causes maximum expiration. (ix) Respiratory movements are controlled by CO_(2) concentration of arterial . blood. (x ) Tidal volume is equal ot the vital capacity of the lungs.

Fill in the blanks with correct words : (a) Diaphragm contracts to help in "........." while the contraction of abdominal muscles helps in "........." (b) vital capacity of trained athletes is "........." than that of non-athletes while the vital capacity of non- smokers is "........." than that of smokers. ( c) Leeches Po_(2) is "........." than the venous Po_(2) while arterial Po_(2) is "........." than the alveolar Po_(2) ( e ) The volume of air left in the lungs after a maximum expiration is called "........." while the volume of air breathed out during a normal restful respiration is called "........."
