Solution

Question

Answer

Explanation

What percentage of water from filtrate is returned to the blood as it makes its way through the nephron tubules?

99%

Up to 99% of the water from filtrate is returned to the blood as it makes its way through the nephron tubules. Only 1% will leave the body. When the filtrate (fluid filtered from blood) will pass through the nephron, it will reabsorb into the body and this reabsorption is important to maintain homeostasis of blood volume, blood pressure, plasma osmolarity, and blood pH. And this reabsorption is achieved through Osmosis, Diffusion, and Active Transport.

What is the term used for the process of substances leaving nephron tubules to go to the medullary tissues?

Osmosis

The fluid present in medullary tissue will have low water concentration, thus the kidney tissues will try to absorb lots of water through the process of osmosis from the nephron tubules.

What is the term for substances leaving the medullary tissues, and going into the renal tubules?

Diffusion

Through active or passive diffusion the substances will leave the medullary tissues and enter the renal tubules
