Which condition would you expect to accompany atherosclerosis, a disorder in which arteries lose elasticity and have fatty buildup inside the vessels?.
Increased blood viscosity.
Irregular heartbeat.
High blood pressure.
Low blood pressure.
The Correct Answer is C
Choice A rationale:
Increased blood viscosity is not typically associated with atherosclerosis. While high blood viscosity can contribute to cardiovascular problems, it is not a condition that you would expect to accompany atherosclerosis.
Choice B rationale:
Irregular heartbeat, or arrhythmia, is not typically a condition that accompanies atherosclerosis. While atherosclerosis can increase the risk of certain types of arrhythmias, it is not a direct result of the disease.
Choice C rationale:
High blood pressure, or hypertension, is often associated with atherosclerosis. The buildup of plaque in the arteries causes them to narrow and stiffen, which increases the resistance to blood flow and consequently increases blood pressure.
Choice D rationale:
Low blood pressure is not typically associated with atherosclerosis. Atherosclerosis tends to increase blood pressure rather than decrease it.

Correct Answer is A
Explanation
The correct answer is Choice A.
Choice A rationale:
The pleural fluid functions by lubricating the space between the pleura, allowing the pleura to glide smoothly during inhalation and exhalation. This cushions delicate lung tissues against friction from the ribs and the chest wall itself.
Choice B rationale:
The fluid in the pleural cavity does not warm and moisten lung tissue. This is not one of its primary functions.
Choice C rationale:
The fluid in the pleural cavity does not prevent bacteria from entering lung tissue. This is not one of its primary functions.
Choice D rationale:
The fluid in the pleural cavity does not assist in the diffusion of oxygen across the respiratory membrane. This is not one of its primary functions.
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.
