is a pale, transparent, unscented, tasteless liquid that is important to life.
A water molecule has three atoms which include two hydrogen atoms and one
oxygen atom. You can remember this by H2O. All known forms of life need water.
Humansdrink water which has qualities compatible with the human body. About seventy percent of the Earth’s surface is covered with water and the
oceans hold about ninety-six percent
of all Earth’s water. Water also comes in three forms that are solid, liquid,
and gas. Water is important for the
body because our body uses water in all its cells, organs, and tissues.Water in the body have
many functions that include regulating body temperature,
lubricating joints, carrying nutrients and oxygen to cells, protecting body
organs and tissues, helps to dissolve minerals and other nutrients to make them
accessible to the body, and helps to prevent constipation. Because the human body loses water through breathing, sweating, and digestion, it’s important to rehydrate by drinking
fluids and eating foods that contain water.
The human body can go eight to ten days without water. The body needs food and
water to survive. At least sixty
percent of the adult body is made of water and every living cell in the
body needs water to keep functioning. The
human body has lots of important
jobs and it needs water to do
many of them. For instance, our blood which contains a lot of water carries oxygen to all the cells
of the body. Without oxygen
those tiny cells would die, and the
body would stop working.Most water moves through the body by osmosis.
Osmosis is where you take in water and it hydrates the cells, takes the fluid
and liquid the body needs, then returns to the bladder or intestinal tract by
reverse osmosis to excrete toxins, waste and unneeded fluids.Although we need
to drink water to survive water is also important to our body because we need
it to cook healthy meals for our body. Most bacteria do not live above 120°F,
and as we increase the temperature we kill more of them. At 102°F most bacteria can no longer
reproduce. We also need water to brush our teeth, so we don’t get a mouth
disease such as gingivitis. So not only is water important for our body, but it
is also important in the use to help our body remain healthy.
