D
Peritubular nephrons
Verified step by step guidance1
Understand the structure of the nephron, which is the functional unit of the kidney, consisting of the renal corpuscle and the renal tubule.
Recognize that nephrons are categorized based on the length of their loops of Henle and their location within the kidney.
Identify the two main types of nephrons: cortical nephrons and juxtamedullary nephrons.
Cortical nephrons have relatively short loops of Henle that barely extend into the medulla, primarily located in the renal cortex.
Juxtamedullary nephrons have longer loops of Henle that extend deep into the medulla, playing a crucial role in concentrating urine.
