ELI5:What exactly happens in your body when you drink water?

I get solid food, but what specifically happens when water enters the stomach and then afterwards.

Your body balances the water in the blood, the cells, and the spaces in between. A small amount stays in the intestines to help digestion while most is absorbed into the body across tiny pores. When the water crosses the pores it also helps transport vital electrolytes into your body. Then the water enters the blood stream and quickly reaches a balance with the other spaces: the insides of cells and in between the cells. The kidneys use the water in your blood to filter the waste products into urine. Some water even goes back into the lower intestines to help make stool.
