Correct Option: (A) is much higher compared to that of O2
Correct Option: (B) higher temperature Explanation: Lower temperature is favourable for formation of oxyhaemoglobin.
Correct Option: (B) <1mm Explanation: Thickness of diffusion membrane is approx 0.2mm.
Correct Option: (C) from tissue to blood and blood to alveoli. Explanation: CO2 moves in body from tissue to blood to alveoli to outside.
Correct Option:(B) 25mm Hg → 50% Explanation: pO2 when 50% of Hb is saturated is calculated to be 25mm Hg.
Correct Option: (A) 12-16 times/ minute
Correct Option: (B) RV + ERV
Correct Option: (A) IC Explanation: Spirometer can measure volume of air inspired or expired and not volume of air still present in lungs i.e RV.
Correct Option: (D) CO2 on oxyhaemoglobin Explanation: Bohr effect is displacement of O2 in oxyhaemoglobin due to increase in partial pressure of ...
Correct Option: (B) more in alveolar air than in expired air Explanation: pCO2 in alveolar air is 40mm Hg and in expired air is 32mm Hg.
Correct Option: (B) Thyroid cartilage Explanation: Thyroid cartilage from a subcutaneous projection, prominent in male.
Correct Option: (D) abdominal breathing
Correct Option:(C) Pulmonary ventilation involves diffusion of gases between blood and tissues. Explanation: Pulmonary ventilation means breathing...
Correct Option: (C) Site of actual diffusion of O2 and CO2 between blood and atmospheric air. Explanation: Respiratory part comprises of respirato...
Correct Option: (D) A - q, B - r, C - p, D - s
Correct Option: (C) Maximum amount of air a person can inhale after forced expiration.
Correct Option: (B) External nostrils to terminal bronchioles.
Correct Option: (C) Epiglottis guards the entry of air in larynx. Explanation: Epiglottis guards entry of food in larynx.
Correct Option: (A) A = Pleural membrane, B = Alveoli, C = Pleuralfluid, D = Bronchiole
Correct Option: (A) Trachea, primary, secondary & tertiary bronchi, initial bronchioles. Explanation: Cartilaginaous rings are found in the co...
