WATER IS LIFEBarbora Vargová, Kristína Paleschová,

WaterThe human body contains lots of water. Our body consists about 70% water. Our brain is about 85% and our bones are about 33% water. Water is very important for the human body. We can live for four weeks without food, but we can‘t live for more than about three days without water.

• We need drink about 8 glasses of water every day. We need water, because it keeps our blood healthy. Our blood is about 50% water.

• If we don‘t drink water, our body gets dehydrated. If we‘re dehydrated, our kidneys and our brain don‘t work. Then we get very sick.

Water at home• We use a lot of water at home. We drink water

and we cook with water. We also use water for washing.

• We use about 80 litres of water when we take a bath. We use about 27 litres of water when we take a shower. We use water to brush our teeth and we also need water to flush the toilet. We use about 9 litres of water every time we flush.
