WebThe relative number of cortical and juxtamedullary nephrons and the lengths of their loops of Henle determine the ability of the kidney to concentrate the urine. In humans, about 85% of the nephrons are cortical nephrons and about 15% are juxtamedullary nephrons. Kangaroo rats, which live in extremely arid environments, never need to drink water. WebCorrect option is A) Juxtamedullary nephrons form about 15% of total nephrons. Their glomeruli are found in the inner margin of the cortex. They control plasma volume when …

Juxtaglomerular apparatus - Wikipedia

The juxtaglomerular apparatus (also known as the juxtaglomerular complex) is a structure in the kidney that regulates the function of each nephron, the functional units of the kidney. The juxtaglomerular apparatus is named because it is next to (juxta- ) the glomerulus. The juxtaglomerular apparatus consists of three types of cells: 1. the macula densa, a part of the distal convoluted tubule of the same nephron WebThe nephron loop of juxtamedullary nephrons is the apparatus that allows the nephron to concentrate urine. The loop is a countercurrent multiplier system in which fluids move in opposite directions through side‐by‐side, semi‐permeable tubes. Substances are transported horizontally, by passive or active mechanisms, from one tube to the other. stiffness in ankles and feet
