Growing teeth: Human teeth start growing while the baby is still in its mothers womb, even though they don't surface until after the child is born.

Shrinking bodies: In the morning you are taller than at the end of the day. This is because your body tissues, such as cartilage, compress as you go throughout your day causing your body to shrink an inch or two.

The large intestine is green while the small intestine is orange.

Brain Size: An adult human brain usually weighs around three lbs. and is around the same size as both of your fists put together.

Curly hair: People with straight hair are more likely to get tangles than people that have curls in their hair.

Not so small intestine: Don't let the name "Small intestine" fool you because its the longest organ in the human body(even longer than the large intestine, go figure). The small intestine can stretch anywhere from 15 to 30 feet, and is tightly packed inside of the abdomen.

Everyone has a different smell: Every individual has their own unique smell that different from everyone else. This is how infants can recognize their mothers.

No hair grows like facial hair: Facial hair grows at an extremely fast rate, quicker than any other hair on the body. Hair that's not their in the morning can can be their by late afternoon.

Gluteus Maximus: The biggest and one of the strongest muscles in our bodies is our rear end.

Importance of the tongue: Even as you sleep, your tongue is hard at work, forcing saliva down your throat.

Ever growing finger nails: Fingernails grow averagely at about a tenth of an inch a month, that's over an inch a year!

Endless supply of sperm cells: A male human's testicles can create up to 10 million sperm cells a day. That's enough cells to populate the world in a matter of months.

The hard working heart: The human heart does more work than any other muscle in the human body. Pumping about 2 oz of blood with every heartbeat.

Our smallest organ is the same size as a grain of rice: The pineal gland crates melatonin which the brain uses to moderate sleep. It's the smallest organ in the human body, being about 5 mm in size, the equivalent to a grain of rice.

The heaviest human organ: Inside of the human body the heaviest organ is the liver at 3 1/2 lbs. However the heaviest organ that's apart of the human body is our skin. Human skin can way up to 10 lbs.
