Water: a transporter

Water is essential because it transports nutritional elements to cells and helps removing waste. It contributes to the exchanges between cells, their interstitial fluid and blood capillaries

Certain organs and body parts are particularly rich in water (3): kidneys (79% water); heart 973% water) , lungs (83%); brain (73%); liver (71%); skin (64%); bone (31%); adipose tissue teeth (10%).

Since muscles contain more water than adipose tissue, a muscular person has a larger proportion of water in his body than a person with more adipose tissue.

Dehydration can impact the proper functioning of the body.(4).

Water and waste removal

Water also serves to remove waste . An important source of waste comes from proteins, in the form of nitrogenous waste (urea, creatinine, ammonium ions, urates). They are eliminated via urine after an intense process of filtration, reabsorption, secretion and elimination in the kidneys.
So to be healthy, it is important to drink water in order to eliminate it!

Did you know?

We have approximately 3 liters of blood in our body. The two kidneys filter about 180 liters of blood volume a day (125 ml/minute): this quantity is filtered 50-60 times a day (5). Yet, we eliminate only 1 to 2 liters of urine a day; the kidneys have extraordinary powers of filtration and concentration!
