dehydration synthesis
Yes. Whenever the body discharges any fluids from the body they lose water. This includes vomit, diarrhea, blood, tears, sweat, csf.... you get the idea.
you get dehydrated (lose body water) by doing lots of exercise or doing a tiring activity
The human body is denser than water. The density of the human body is about 985 kg/m^3, while the density of water is 1000 kg/m^3. This is why your body floats in water.
75%
Muscle, Skin, Fat, Blood and Cartilage are some big components. And don't forget water, the human body would lose over half it's weight if all the water were removed.
The average human body is made up of about 60% water, so 50% of a human body would be about 30% water.
Without water humans and mammals will die. Water is a large component of the human body. If we lose too much water our organs begin to fail.
the human body has 32 teath.
That depends on the person - a live human body is about the same density as water - some people sink, some float - just. In other words, you are about weightless in water.
The water loss is due to sweating to cool the body.
