Transport of Gases

Arrange the given steps of respiration mechanism in the order they occur in (I) Diffusion of gases across the alveolar membrane (II) Diffusion of O_(2) and CO_(2) between blood and tissue (III) Breathing or pulmonary ventilation (IV) Utilisation of O_(2) by the cells (V) Transport of gases by the blood

For completion of respiration process, write the given steps in sequential manner: (a) Diffusion of gases ( O_(2) and CO_(2) ) cross alveolar membrane. (b) Transport of gases by blood. (c) Utilisation of O_(2) by the cells for catabolic reactions and resultant release of CO_(2) . (d) Pulmonary ventilation by which atmospheric air is drawn in and CO_(2) rich alveolar air is released out. (e) Diffusion of O_(2) and CO_(2) between blood and tissues.

Given below is a list of different steps (i-vi) involved in respiration. (i) Utilisation of O_(2) by the cells for cataolic reactions. (ii) Transport of gases by the blood. (iii) Pulmonary ventilation by which atmospheric air is drawn in and CO_(2) is released out. (iv) Release of resultant CO_(2) . (v) Diffusion of O_(2) and CO_(2) between blood and tissues. (vi) Diffusion of gases ( O_(2) and CO_(2) ) across alveolar tissues. Select an option which has correct sequence of all the steps.

What are the reasons why plants can get along without respiratory organs? a. Each plant part takes care of its own gas exchange needs. There is very little transport of gases from one plant part to another. b. Plants do not present great demands for gaseous exchange, root, stem and leaves respire at rates far lower than animals do. c. The distance that gases must diffuse even in large, bulky plants is not great.

Identify the correct statement with reference to transport of respiratory gases by blood.

Find out the example in which due to absence of respiratory pigment transport of respiratory gases does not takes place.
