Facts About Babies and the Human Body 

The largest cell in the human body is the female egg and the smallest is the male sperm. The ovum is large enough to be seen by the naked eye: about a millimeter. The female’s ovaries are born with the total egg supply she will have during her fertile years.

Babies are pound-for-pound stronger than an ox, so their kicks can be pretty powerful. Their teeth start growing six months before they are born, and the second set of teeth are in the gums long before birth.

A fetus develops the whorls of their fingerprints at the age of three months; they will never change throughout life and are among the last things to disappear after death (Medlineplus).

Your eye color is determined by the genes of your parents, but most babies are born with blue eyes, for the pigment melanin needs time to reveal the true eye color. Your eyes are always the same size from birth through life, but your nose and ears never stop growing. The human body grows in 7 year cycles.

Provided there is water the average human can survive a month or two without food, but sleep deprived people experience radical changes after only a few sleepless days.

The brain itself cannot feel pain but it is surrounded by tissues, nerves and blood vessels that are most receptive to pain. 80% of the brain is water and is not the grey firm mass often portrayed but a squishy, pink jelly-like organ which requires water to be kept hydrated.

There are 60,000 miles of blood vessels in the body, compared to 25,000 to go around the earth (STEM Newcastle).
