Which factor increases a woman's risk for UTIs?

A. Atherosclerosis is the build-up of plaques in the arteries, leading to narrowed and hardened arteries, not dilation and weakening.

B. Varicose vein involve the swelling and twisting of veins, usually in the legs, due to valve failure, not the dilation of a blood vessel wall as in an aneurysm.

C. Aneurysm is the local dilation or bulging of a blood vessel due to a weakening of the vessel wall, which can lead to rupture and serious complications.

D. Thrombophlebitis is inflammation of a vein associated with clot formation, not the dilation of a blood vessel.

A. It is the one for which capillary membranes become extra permeable during inflammation, allowing certain proteins to move to tissues. This describes the interstitial fluid, not the intracellular fluid (ICF). During inflammation, the capillary membranes allow proteins to move into the tissues, which is part of the extracellular fluid (ECF) compartment.

B. It is located within the bloodstream. This describes the intravascular fluid, which is a part of the extracellular fluid (ECF) compartment, not the intracellular fluid (ICF).

C. It is located inside the cells. The intracellular fluid (ICF) is the fluid contained within the cells of the body, making up about two-thirds of the total body water.

D. It is the one containing hormones intended to balance red blood cell count. Hormones related to red blood cell production, such as erythropoietin, are not specific to the intracellular fluid compartment. This statement does not accurately describe the ICF.
