At my school I am learning about the human body, so I decided to make a list with facts I found in books that talk about the human body.
- Unlike most organs in the body, you have two kidneys. Even if one of them is damaged or removed, your other kidney can keep on doing its job.
- After you are born, the umbilical cord is tied off and cut. As you grow that stump of tissue becomes a bellybutton.
- When woman is born she already has all the egg cells she will ever make.
- People who need glasses have muscles that are either too tight or too loose to allow the lens to focus well.
- In Victorian times, you'd been told to brush your hair a hundred times a day!
- A giraffe has such a long tongue (53 cm) that it can touch its ear.
- There are 100,000 muscles in an elephant's trunk, while you have only 650 skeletal muscles in your whole body.
- The brain stops growing at the age of fifteen.
- Your fingerprints are completely unique; even identical twins have different prints.
Do you like learning learning about the human body? What's your favorite system? My favorite system is the respiratory system.
