Process writing of maintain balance of water in the body
Answers
Answer:
The kidneys produce urine of different concentrations in order to maintain water balance. ... The more fluids we drink, the more dilute our body fluids become, so the kidneys produce more urine to eliminate the excess. Sodium consumption can help to balance the fluids in our body.
Explanation:
In the body, several mechanisms work together to maintain water balance. These include
Thirst
Interaction of the pituitary gland and kidneys
Osmosis
Thirst is one of the most important mechanisms to maintain water balance. When the body needs water, nerve centers deep within the brain are stimulated, resulting in the sensation of thirst. The sensation becomes stronger as the body’s need for water increases, motivating a person to drink the needed fluids. When the body has excess water, thirst is suppressed.
An interaction between the pituitary gland and the kidneys provides another mechanism. When the body is low in water, the pituitary gland secretes vasopressin (also called antidiuretic hormone) into the bloodstream. Vasopressin stimulates the kidneys to conserve water and excrete less urine. When the body has excess water, the pituitary gland secretes little vasopressin, enabling the kidneys to excrete excess water in the urine.
In osmosis, water flows passively from one area or compartment of the body to another. This passive flow allows the larger volumes of fluid in the cells and the area around the cells to act as reservoirs to protect the more critical but smaller volume of fluid in the blood vessels from dehydration.
