Gaseous exchanges continue in lungs without interruption even during expiration. Explain.

Gaseous exchange continues in the lungs without interruption due to:

Gas exchanges continue uninterrupted in ----- even after a forceful expiration.

Site of gaseous exchange in lungs is :

Give suitable explanations for the following: Why does gaseous exchange continue in the lungs even during expiration ?

Read the following four statement (i) - (iv) with certain mistakes in two of them. (i) A water breather expends much more energy in ventilating its respiratoru surface than an air-breathing one. (ii) Lungs become empty after forceful expiration. (iii) Exchange of gases in the lungs are interrupted during expiration. Respiratory movement are controlled by CO_(2) concentration of arterial blood. Which of the above two statements have mistakes ?

The site of gaseous exchange in the lungs is:

Explain why (or how) : (a) In a sound wave, a displacement node is a pressure antinode and vice-versa, (b) Bats can ascertain distances, directions, nature and size of obstacles without any eyes, (c) a violin note and sitar note may have the same frequency, yet we can distinguish between the two notes, (d) Solids can support both longitudinal and transverse waves, but only longitudinal waves can propagate in gases, (e) The shape of pulse gets distorted during propagation in a dispersive medium.

The volume of air in the lungs and the rate at which it is exchanged during inspiration and expiration was measured. The following diagram shows a group of the lung volumes and capacities : Study the diagram carefully and explain briefly the following: (a) Tidal volume (b) Inspiratory reserve volume (c) Expiratory reserve volume (d) Vital capacity (e) Residual volume
