Which of the following is a common feature of Malpighian corpuscle, PCT and DCT?

The Malpighian corpuscle, PCT, and DCT, are situated in the renal cortex, which is the outermost region of the kidney. The renal cortex contains the majority of the functional units of the kidney, known as nephrons, where urine formation takes place. As the filtration and processing of blood occur in the renal cortex, it is a critical region for the overall functioning of the kidney and the maintenance of bodily fluid and electrolyte balance.
