What is the approximate amount of $CO_2$ eliminated by our lungs per day?

Persons living at high altitude will have

The maximum amount of water vapour that the atmosphere can hold at a given temperature is known as:

For completion of the respiration process,write the given steps in sequential manner.
$(a)$ Diffusion of gases ($O_2$ and $CO_2$) across 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.

Which of the following steps is $NOT$ involved in the process of respiration?

Respiration is the physiological process in which
