Answers

1. Fiction
The human eye can see visible light, only a small part of the electromagnetic spectrum. This spectrum also includes radio waves, microwaves, infrared and ultraviolet light, X-rays, and gamma rays, which humans cannot see.

2. Fiction
Adult humans have 206 bones.

3. Fact
The lymphatic system is part of the body’s defense system. It removes bacteria from tissues and produces lymphocytes, or white blood cells, macrophages, and antibodies.

4. Fiction
The auditory ossicles are three small bones in the ear that are connected to each other, and that enable us to hear.

5. Fiction
The stomach does not absorb much at all of the food, water, and electrolytes that pass through it, though it does absorb some substances, including iron, alcohol, and some drugs.

6. Fact
The longest and strongest bone in the human body is the femur.

7. Fiction
The appendix is attached to the large intestine.

8. Fact
Humans have two sets of teeth during their lives. The first consists of 20 teeth. These are called primary teeth. Then 28 permanent teeth replace them, along with four molars commonly called wisdom teeth.

9. Fact
The wall of the stomach is composed of four layers: the mucosa, submucosa, muscularis, and serosa.

10. False
A typical adult human head weighs about 5 kilograms. The brain accounts for about 1-1.5 kilograms.

11. False
We are born with genes programmed for handedness. About 90 percent of people are right-handed. A very small number of people are ambidextrous—that is, they can use both hands equally.

12. False
Human skin cells divide between 50 and 70 times.

13. False
Nerve cells, or neurons, are the basic units of the nervous system. The human body contains billions of neurons. The brain alone contains some 100 billion neurons.

14. False
More than 98 percent of human DNA is identical to that of chimpanzees, gorillas, and other apes. The remaining quantity contains what distinguishes us.

15. False
The heart pumps blood. Lympathic fluid is pumped by a process called peristalsis, the contraction of muscles around the lymphatic vessels.

16. False
Some nerves, such as optic and spinal-cord nerves, are so specialized that they have very limited powers of regeneration. But other nerves can be easily reconnected and even regain feeling.

17. True
The sensation that we’re being pricked by pins and needles is a phenomenon called paresthesia. This is commonly caused by compressed nerves that run between the bones and the skin.
