Question

multiple - choice question
the activities in the loop of henle can be summarized as
active removal of salt and active removal of water
active removal of water and passive removal of salt
acticve removal of salt and passive removal of water
rewatch

Explanation:

In the loop of Henle, the ascending limb actively transports out salt (using energy - dependent mechanisms like ion pumps). The descending limb is permeable to water, and water moves out passively (down its concentration gradient) due to the high - salt environment created in the medulla by the active salt transport in the ascending limb.

Answer:

Active removal of salt and passive removal of water
