Many people believe this to be true, however it is just another myth. You do not lose anymore heat from head than you do from any other body part.
Through the urine, through our exhaled breath and through sweating.
In humans, oxygen comes into the body through the lungs and is then transported throughout the body by red blood cells.

The cells become millions of cells in the human body through the process of replication.
Basic Answer:For most humans, only 40% of the body is not water.Longer Answer:The human body has a variable water content that changes daily and with age and gender and body type.On average, adult humans have 57 to 60 % water by mass.At birth, a baby can have up to 75% water weight and this decreases with age.Obese individuals can have as little as 45% water weight.Women tend to have a few percent less water weight than men, but this is largely a difference in muscle and fat between individuals.
60% in male humans
70% of a humans body is made of water.
Mostly...The human body is 61.8 percent water by weight.
Up to 60 percent of the human body is water.

In humans, oxygen comes into the body through the lungs and is then transported throughout the body by red blood cells.
That depends on the size of the individual.Younger humans have proportionally larger heads than fully-grown humans but the remainder of the system, such as nerves through the body, are proportional to their body and will grow evenly. The head and brain will grow less when compared to the rest of the body but goes through many important stages of development. Most of that development requires brain cells to make new connections and grow instead of dividing into more cells.
0-2 % in males and 15-20% in females
Capillaries do not influence the percent of body fluid. The fluid leaving the circulation through proximal end comes back through distal end.
Including your head itself, your human body is about seven of your heads tall, and you can fit about nine in your whole body
Humans have a structure in their heads called the pineal body or gland. It isn't an eye, and in humans it's really not even vaguely eye-like other than being sort of approximately round.
It does the same thing it does for humans. Pumps blood through out the body.
