An effective maneuver for dislodging a foreign object in someone that is choking is called?.

hoice A rationale:

Cilia do not propel air into the lungs, they are involved in moving mucus and trapped particles.

Choice B rationale:

Cilia do not trap food or prevent its entry into the windpipe. This is the role of the epiglottis, not cilia.

Choice C rationale:

Cilia in the airways help to propel trapped debris and mucus upward to be expelled by the body.

Choice D rationale:

Cilia do not have a role in olfaction or the sense of smell.

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.
