Explanation:

Water is essential for the normal functioning of the organ systems in the body. Dehydration occurs when the water we take in is less than the water we lose. Water is lost fr the body through sweating, breathing, urination and defecation. Disease conditions like diarrhea and vomiting also cause loss of water.

When the body senses dehydration, there is a thirst signal to tell us to drink more water. The body then proceeds to the water leaving through the kidneys thereby conserving water in the body. This explains the concentrated and colored urine during dehydration.
