Correct Answer is B
Explanation
Choice A rationale:
Osmosis is the process by which water molecules move from an area of high concentration to an area of low concentration across a semi-permeable membrane. It does not directly involve the exchange of oxygen and carbon dioxide in capillaries.
Choice B rationale:
Diffusion is the process by which molecules move from an area of high concentration to an area of low concentration. At the respiratory membrane, where the alveolar and capillary walls meet, gases move across the membranes, with oxygen entering the bloodstream and carbon dioxide exiting.
Choice C rationale:
Filtration is a process that separates particles from a liquid or gas, and it does not directly involve the exchange of oxygen and carbon dioxide in capillaries.
Choice D rationale:
Colloid osmotic pressure refers to the pressure exerted by proteins in a blood vessel’s plasma that usually tends to pull water into the circulatory system. It does not directly involve the exchange of oxygen and carbon dioxide in capillaries.
