Which of the following statements about urine formation are correct?
The juxta glomerular apparatus regulates glomerular filtration rate by releasing renin.
The loop of Henle is exclusively located in the cortex of the kidney in all nephrons.
ADH facilitates water reabsorption in the collecting duct to concentrate urine.
Cortical nephrons have long loops of Henle that extend deep into the medulla.

Statement B is incorrect because while the loop of Henle dips into the medulla, it is not the case for all nephrons. Statement C is correct as ADH plays a role in water reabsorption. Statement D is incorrect because cortical nephrons typically have shorter loops of Henle.
