What is the most important role that water plays for living organisms

-well, we all need water as living organisms in order to live. water helps us clean our body (just like you clean yourself in a shower to clean your skin),but drinking water helps you to take a shower inside your body! (sounds weird but true XD) you get the point... here are a few things water does to our body:

- water helps helps our skin to look beautiful (you can say youthful skin) and even beauty itself.

- it trashes body waste and toxins (like i said above)

- it gives us nutrients and minerals

- it helps us to maintain out blood pressure

- it also helps to regulate our body temperature

- it transfers oxygen through the whole body

- it helps with digestion

-  weigh loss

- gives you energy ( thats why when your exercising you need to drink water every 15 min XD)

-prevents from you have a stinky breath *-*

- it helps with back-pain, headaches, heart health...etc

- it helps boost your immune system

- increases your brain power

so those are what i got for you about why water is important to us  :D
