Do you know how much water is in your body?
About 60% of our body is water.
A person who weighs 60 kg will have a whopping 36 kg of water stored in their body.
It can be said that humans are made of water. The water in this body is called “body fluids”.
About 4.6 billion years ago, the first life forms on Earth originated in the ocean.
Eventually, they moved from the sea to the land and evolved into humans. It is a remnant of this that our body fluids resemble seawater because they contain ions (electrolytes).
It can be said that our body has an “inner sea.”
