13 Amazing Ways Your Body Works

ways your body works

Six cups of saliva, 260 billion new red blood cells and 20,000 thoughts. These are just a few of the amazing feats your body accomplishes each day. Learn about these achievements and more ways your body works, as featured in Reader’s Digest.


1. Cleans gallons of blood – The kidneys are two small organs responsible for filtering and recirculating about 50 gallons of blood daily. If the kidneys don’t work correctly, a machine is required to remove waste from the blood.

2. Breathes 25,000 times – The brain stem is responsible for allowing your body to automatically breathe at least 25,000 times daily. When resting, the body uses about 7 to 10 ounces of oxygen each minute.

3. Blinks 15,000 times – Each day the eyes blink this many times to remove dust and dirt to keep tissues clean.

4. Produces sweat – On average, most people take about 8,000 to 10,000 steps daily. To keep cool, your feet produce more than two cups of sweat. It’s not surprising that your shoes and socks get funky by the end of the day.

5. Sheds dead skin cells – Each day your body gets rid of 50 million dead cells, which is equivalent to 30,000 to 40,000 cells every minute. Scientists report that 1 square inch of skin has 60,000 pigment cells, 650 sweat glands, 20 feet of blood vessels and over 1,000 nerve endings.

6. Generates thoughts – Over 100 billion brain cells communicate with each other 5 to 50 times per second. This rapid-fire process can move up to 270 mph, allowing you to quickly see and identify things.

7. Regenerates the body’s skeleton – Every year the adult skeleton repairs, replaces and rebuilds 10 percent of its blood vessels and nerves to keep bones healthy and strong.

8. Balances the internal thermostat – The body naturally adjusts to changes in temperature throughout the day. If you get overheated, blood vessels dilate to allow heat to escape. When the weather turns cold, they tighten and turn off sweat glands. If your body’s internal temperature drops to 97 degrees, you start shivering to warm up.

9. Rejuvenates the stomach lining – Hydrochloric acid in your stomach breaks down foods you eat. Since the acid is strong, every four or five days the stomach lining is regenerated to keep it healthy.

10. Cleanses wounds – When your skin is cut, blood vessels underneath start bleeding to cleanse the injury. Soon, the body forms a clot to stop the blood flow. Meanwhile, white blood cells kill bacteria and your immune system releases histamine to promote blood flow to the area for healing.

11. Battles cancer – The body has trillions of cells. Sometimes genetic mutations occur that create cancer cells, which can replicate and form a tumor. To fight cancer, when cells divide, proofreading enzymes fix DNA errors. If this process fails, afflicted cells know to kill themselves.

12. Regulates heart beat – Every day the heart beats about 100,000 times. That’s about 3 billion times during a lifetime. Your body has about 100,000 miles of blood vessels, and your heart pumps 2,000 gallons of blood daily.

13. Prevents choking –The back of the mouth is designed to keep you from choking on food and beverages. When swallowing, the soft palate covers the nasal cavity and the epiglottis covers the trachea so foods and drinks head into the esophagus and down to the stomach, instead of out the nose or into the lungs.
