he correct answer is Option A : (D), (A), (C), (B), (E).
Here's the reasoning behind this order :
(D) Pulmonary ventilation by which atmospheric air is drawn in and CO2 rich alveolar air is released out.
Respiration begins with pulmonary ventilation (breathing), which allows the atmospheric air to enter the lungs and CO2-rich air to be exhaled.
(A) Diffusion of gases (O2 and CO2) across the alveolar membrane.
Inside the lungs, oxygen diffuses from the alveoli into the blood, and carbon dioxide diffuses from the blood into the alveoli across the alveolar membrane.
(C) Transport of gases by the blood.
Once in the bloodstream, oxygen and carbon dioxide are transported to and from the body's tissues.
(B) Diffusion of O2 and CO2 between blood and tissues.
Oxygen diffuses from the blood into the body's tissues, and carbon dioxide diffuses from the tissues into the blood.
(E) Utilisation of O2 by the cells for catabolic reactions and resultant release of CO2.
Finally, oxygen is used by cells for metabolic processes, creating carbon dioxide as a byproduct.
Therefore, the sequence is (D), (A), (C), (B), (E).

Respiration Sequence of Steps:
1. Pulmonary Ventilation (D): In this step, atmospheric air is drawn into the lungs through inhalation, and CO2 rich alveolar air is released out through exhalation.
2. Diffusion of Gases across Alveolar Membrane (A): Oxygen (O2) from the inhaled air diffuses into the blood in the lungs, while carbon dioxide (CO2) from the blood diffuses into the alveoli to be exhaled.
3. Transport of Gases by the Blood (C): Oxygen is transported by the blood to all the body tissues, while carbon dioxide is transported from the tissues back to the lungs.
4. Diffusion of O2 and CO2 between Blood and Tissues (B): Oxygen diffuses from the blood into the cells of the tissues, where it is used for cellular respiration. Carbon dioxide produced by cellular respiration diffuses into the blood to be transported back to the lungs.
5. Utilization of O2 by Cells and Release of CO2 (E): Oxygen is utilized by the cells for catabolic reactions to produce energy, while carbon dioxide is released as a byproduct and transported back to the lungs for exhalation.
Therefore, the correct sequence of steps in respiration is (D), (A), (C), (B), (E).
