Answer:
Basically,<u> Lactose </u>a disaccharides of (glucose and galactose) cannot directly be absorbed through the wall of small intestine to reach the blood stream. Usually they are hydrolyzed by LACTASE enzyme to the constituents monosaccharides which are readily absorbed through the walls of the small intestine.
Therefore, in absence or lack of lactase, there is retention/accumulation of intact / unmetabolized Lactose in the lumen of small intestine, which eventually moved into the COLON.
Intestinal bacterial in the colon breaks down(metabolize) the colon lactose by fermentation, with the by products of CO2, H2, and CH4.
These gaseous by products lead to different abdominal symptoms(bloating, flatulence) experienced by individuals with Lactose tolerance.
Consequently,the increase solute potential of the colon raises the osmotic pressure (since the water potential is very low). These gradients draw water in by Osmosis with the bowel filled with water. leading to swelling
its an ecosystem every living thing in this planet is in one.

The kidneys are the organs responsible for filtering the body from excess materials like salts and other by-products that can be found from ingesting food and medicines. Without the functions of the kidneys the body will get poisoned because it can't process such waste and bring it to the excretory system in the form of urine and feces.
The dialysis machine acts out as kidneys in the body, when it is attached, blood is transfused into the machine and the machine filters the blood. As this happens, the blood is then returned to body clean and free from toxins.
