What will be the $$pO_2$$ and $$pCO_2$$ in the atmospheric air compared to those in the alveolar air? (i) $$pO_2$$ lesser, $$pCO_2$$ higher (ii) $$pO_2$$higher, $$pCO_2$$ lesser (iii) $$pO_2$$higher, $$pCO_2$$ higher (iv) $$pO_2$$ lesser, $$pCO_2$$ leser
$$pO_2$$ higher will be higher and $$pCO_2$$ will be lesser in the atmospheric air as compared to those in the alveolar air.
The partial pressure of oxygen in atmospheric air is higher than that of oxygen in alveolar air. In atmospheric air, $$pO_2$$ is about 159 mm Hg. In alveolar air, it is about 104 mm Hg.
The partial pressure of carbon dioxide in atmospheric air is lesser than that of carbon dioxide in alveolar air. In atmospheric air, $$pCO_2$$ is about 0.3 mm Hg. In alveolar air, it is about 40 mm Hg.
Match the items given in column I with those in column II and select the correct options given below: Column I Column II a. Tidal volume 1 2500-3000 mL b. Inspiratory Reserve volume 2 1100-1200 mL c. Expiratory Reserve volume 3 500-550 mL d. Residual volume 4 1000-1100 mL
Tidal Volume and Expiratory Reserve Volume of an athlete is $$500$$mL and $$1000$$mL, respectively. What will be his Expiratory Capacity if the Residual Volume is $$1200$$mL?
