MICROANATOMY

Detailed explanation-1: -Water Intake On average, 180L of water is filtered by the kidneys daily. However, only 1.5-2L actually ends up being excreted as urine. This means almost 99% of the water filtered is either reabsorbed into the circulation or enters the interstitium.

Detailed explanation-2: -Tubular reabsorption is the process that moves solutes and water out of the filtrate and back into your bloodstream. This process is known as reabsorption, because this is the second time they have been absorbed; the first time being when they were absorbed into the bloodstream from the digestive tract after a meal.
