In which lymphatic organ do T cells mature?.

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.

Choice A rationale:

Atherosclerosis does not involve the stretching of arteries.

Choice B rationale:

Atherosclerosis is characterized by the hardening of the arteries due to the buildup of plaque.

Choice C rationale:

Aging of the arteries is not the correct term for atherosclerosis.

Choice D rationale:

While plaque buildup is a feature of atherosclerosis, this choice does not fully capture the hardening aspect of the condition.
