Question

lo 6.2. what is the function of the renal cortex?
regulate blood pressure
produce bile
produce red blood cells
break down proteins
filter the blood and produce urine.

Explanation:

The renal cortex is part of the kidney. The kidney's main role is filtering blood and making urine. Regulating blood pressure is more related to kidneys overall (like renin - angiotensin - aldosterone system, but not specifically the cortex in isolation among these options). Producing bile is liver function. Producing red blood cells is bone - marrow (with kidney's erythropoietin role, but not the cortex as the main site here). Breaking down proteins is more digestive system related (like liver and proteolytic enzymes in gut). Filtering blood and producing urine is a key function of the renal cortex (where glomeruli are located which start the filtration process).

Answer:

Filter the blood and produce urine.
