Suppose homeostasis in a mammal was suddenly affected such that the osmolarity of the medulla of the kidney was equal along the entire length of the loop of Henle.How would this affect the filtrate at the junction of the descending and ascending loops of Henle?
A)The filtrate would be more concentrated than normal.
B)The filtrate would be less concentrated than normal.
C)The filtrate concentration would not be affected.

The loop of Henle plays a crucial role in establishing the concentration gradient in the medulla of the kidney, which allows for the reabsorption of water from the collecting duct. If the osmolarity of the medulla was equal along the entire length of the loop, then the concentration gradient would no longer be present. As a result, the filtrate at the junction of the descending and ascending loops of Henle would be less concentrated than normal.
