BODY TRIVIA

Your body is an amazing system. If you take good care of it, it will take good care of you. Here are just a few things you may not know that I’d like to share with you today.

Did you know...

The thickness of your skin varies from 1/2 to 6 millimeters, depending on the area of your body.

The four taste zones on your tongue are bitter (back), sour (back sides), salty (front sides), and sweet (front).

The five senses are sight, hearing, smell, touch, and taste.

Your body contains eight pints (3.79 liters) of blood.

The strongest muscle of the body is the masseter muscle, which is located in your jaw.

Muscles normally account for 40% of one's body weight.

There are 230 joints in the body, 37 of which are in your neck.

The large intestines are five ft (.61 m) long and are three times wider than the small intestines.

Most people shed 40 lbs (16.14 kg) of skin in a lifetime.

Your body is 70% water.

When you sneeze, air rushes through your nose at a rate of 100 mph (160.93 km/h).

An eyelash lives about 150 days before it falls out.

Your brain sends messages at the rate of 240 mph (386.23 km/h).

About 400 gallons (1,514.16 liters) of blood flow through your kidneys in one day.

You blink your eyes about 20,000 times a day.

Your heart beats about 100,000 times a day.

Humans breathe 20 times per minute, more than 10 million times per year and about 700 million times in a lifetime.

You have about 100,000 hairs on your head.

There are 10 million nerve cells in your brain.

Each of your eyes has 120 million rods, which help you see in black and white.

Each eye has six million cones, which help you see in color.

One in 12 men is color blind.

Placed end to end, all your body's blood vessels would measure about 62,000 mi (99,779.33 km).

You see with your eyes and hear with your ears, but your eyes must send a message to your brain in order for you to see, and your ears must send a message to your brain in order for you to hear.

Your brain weighs 2 percent of your total body weight. It uses 20 percent of your body's energy.
