Fabulous Body Facts 9
Enjoy:
It takes about six months for a toenail, and three months for a fingernail, to grow from the base to the tip.
The pop you get when you crack your knuckles is a bubble of gas escaping from the joints between finger bones.
A pack-a-day smoker will lose approximately two teeth every ten years.
Beards are the fastest growing hairs on the human body. If the average man never trimmed his beard, it would grow nearly 30 feet (9m) long in his lifetime.
The hairs on your arms are programmed to stop growing every couple of months, so they stay short. But the hair follicles on your head are programmed to grow for years at a time, so this type of hair can grow very long.
An average human scalp has 100,000 hairs.
Every human being has a unique smell shared by no other human being.
Humans are the only primates that don't have dark pigment in the palms of their hands.
If locked in an airtight room, you will die by breathing your own carbon dioxide, which is poisonous, rather than from lack of oxygen.

Fabulous Body Facts 8
Did you know that:
1. A single brain cell can communicate with as many as 25,000 other cells at one time?
2. Waking up to a beeping alarm clock traumatizes the nervous system and can lead to heart attacks in susceptible people? Soft music on a clock radio is a safer alternative.
3. Your heart pumps 3,600 gallons (13,623 liters) of blood in one day?
4. Your body makes 10 billion white blood cells every day?
5. Another word for white blood cell is macrophage, which means "big eater"? This refers to the fact that white cells absorb harmful bacteria.
6. In a human, the only cells without a nucleus are the red blood cells?
7. There are about five million red blood cells in a tiny droplet of blood?
8. It takes about 20 seconds for a red blood cell to circulate through the whole body?
9. A red blood cell has a lifespan of about 120 days?
10. Every square inch of human skin contains about 20 feet (6 m) of blood vessels?
11. Average humans have 93,000 miles of blood vessels in their body?
12. It takes about six months for a toenail, and three months for a fingernail, to grow from the base to the tip?
Bonus point question: Why do we call the chicken pox the "chicken" pox, when it did not come from chickens?

Fabulous Body Facts 4
Here are some interesting and fascinating facts about our very own nervous system.
Did you know that:
1. Causes of spinal cord injuries include motor vehicle accidents (44%), acts of violence (24%), falls (22%), sports (two-thirds of these are from diving accidents) (8%), and other (2%).
2. There are 31 pairs of spinal nerves.
3. If all of the neurons in a person's body were lined up that line would stretch to a length of 600 miles.
4. The average adult male brain weighs 1375 g while the average adult female brain weighs 1275 g.
5. Only 4 percent of brain cells are actually used while the rest are kept in reserve.
6. On average, there are 100 billion neurons in the human brain.
7. The right side of the brain controls the left side of the body and the left side of the brain controls the right side of the body.

Fabulous Body Facts 3
No homework today. I am including the link to the video we watched about the muscles today (6B; 6A will see it tomorrow), in case you wanted to see it again.
Fun video about the muscles
Here are some interesting facts about the muscles. Enjoy!
1. There are more than 600 muscles in the body.
2. You need 72 muscles to speak.
3. A pound of muscle burns 75-100 calories a day just by "being".
4. The tongue is the strongest muscle.
5. The group of muscles that work together to blink your eye are the fastest muscles in your body. They enable you to blink up to 5 times a second. On average, you blink 15,000 times daily. Women blink twice as often as men.
6. The gluteus maximus (your butt muscle) is the largest muscle in your body.
7. Your hand contains 20 different muscles.
8. Muscles account for approximately 40% of your body weight.
9. You take approximately 5 million steps per year using your leg muscles.
10. You have all the muscle you will ever have at birth.
Bonus Point Question: How many muscles does it take to smile? How many does it take to frown?

Fabulous Body Facts 2
I wanted to share some fabulous facts about the brain. Did you know that...
1. More electrical impulses are generated in one day by a single human brain than by all the telephones in the world?
2. The energy used by the brain is enough to light a 25 watt bulb?
3. Your brain is about 2% of your total body weight but uses 20% of your body's energy?
4. There are about 100 billion neurons (nerve cells) in the human brain, the same as the number of stars in our galaxy?
5. The slowest speed at which information travels between neurons is 416 km/h or 260 mph? That's as "slow" as today's supercar's top speed (the Bugatti Veyron clocked at 253 mph).
6. The brain can stay alive for 4 to 6 minutes without oxygen? After that, cells begin to die.
7. The human brain is the fattest organ? It may consist of at least 60% fat.
For a bonus point on a test, can you explain why the brain itself cannot feel pain?

Fabulous Body Facts 1
Did you know that:
1. Every square inch of the human body has about 19 million skin cells?
2. Every hour about 1 billion cells in the human body must be replaced?
3. The average human head has about 100,000 hairs?
4. Hair is so strong that each hair can withstand the strain of 100 grams (3.5 ounces)?
An average head of hair could hold 10-15 tons if only the scalp was strong enough!
5. Hair has the highest rate of mitosis (cell division). An average hair grows 0.3 mm a day and 1 cm per month?
For a bonus point on your next test, answer the following question:
Why does hair turn gray?

Try a Virtual Knee Surgery!
Thank you to Darrein, who brought to this great website to my attention. You can try your hand at being a surgeon, through a variety of virtual surgeries, including knee surgery, hip replacement, and brain surgery. I quite enjoyed doing a knee surgery, and I think I may have to operate on the brain before the weekend is through.
