The human body is an amazing thing. With more than 7,000 miles of veins, 80,000 miles of blood vessels and 100,000 miles of nerve fibers, the human body is literally one big network of interconnected systems and mechanisms. We are able to perform complex actions as easily as if we’re flipping on a light switch in our homes or offices. But how much do we really know about this wonder of the natural world? What facts and figures can we share with friends? Here are interesting charts about the human body that prove we are doctors by nature.
1) The percentage of the human body made up of water
It’s common knowledge that we are made up of a lot of water, but it’s still shocking to see how much. In fact, the human body is about 60% water. It may sound like a lot, but for comparison sake the Pacific Ocean is about 97% water and humans are just a tad more than 1% of the weight of Earth.
The human body is comprised primarily of salt water (water mixed with minerals from blood) which helps regulate our temperature, transports nutrients and oxygen to cells and removes waste products from cells.
2) The average number of heartbeats in a lifetime
What are some interesting charts about the human body that prove we are doctors? One such chart is a lifetime average number of heartbeats. The average person will have roughly 70,000 heartbeats in their lifetime. A baby has around 250 to 350 beats per minute, while an adult ranges from 60 to 100 beats per minute. A heartbeat can be felt in the neck or on the chest. It’s difficult to count them without knowing what the right rate should be, so check with your doctor if you need more information.
3) How much blood the heart pumps in a day
The human heart pumps about 5 liters of blood every minute, which means it pumps about 2.5 billion lits in a day. This is equivalent to 1,200 gallons of water or 2 Olympic size swimming pools. When kidney function ceases If the kidneys are not able to remove waste products from the body, these wastes accumulate and eventually lead to death. How long an average person’s bladder can hold urine: Normally when there is only a little urine left in the bladder, this triggers nerve signals that cause muscles around the urethra to contract and squeeze out any remaining urine. When there’s more than usual liquid in the bladder, then this same muscle contraction does not empty it completely and some urine may dribble into clothing after standing up from sitting down.
4) How many times your stomach acids digest food in a day
A human’s stomach digests food a total of 7 times per day. When you eat, the food goes down the throat and into your esophagus and eventually, into your stomach. Your stomach is lined with hydrochloric acid that helps break down the food so it can be absorbed by your body. This process begins when your stomach releases an enzyme called pepsin, which starts to break down proteins in your food. Your body then produces a hormone called gastrin, which causes cells in the lining of your stomach to produce more hydrochloric acid.
5) How many times you breathe in a day
There are approximately 20,000,000 breaths in a person’s lifetime. Not only that, but every day a person breathes 12-14 times per minute. A newborn baby breathes 10-12 breaths per minute, while an adult breathes 18-20 times per minute. This means the average person takes about 21,000 breaths in a 24 hour period. To put it into perspective, if one were to breathe in and out as fast as they could, they would need 2 hours to finish a full breath cycle.
So how long is your hair? It may be surprising to some people that we have 100,000 hairs on our head at any given time – or approximately 150 strands of hair per square inch! If you’re balding, you may be losing up to 150 hairs each day.
6) How many times you will blink in your lifetime
In your lifetime, you will blink an estimated 1.6 billion times. It takes about 0.3 seconds for a blink to complete, and the average blink lasts about 300 milliseconds. One blink is usually followed by another in quick succession. Blinking may take an even quicker pace when the eyes are irritated or dry from excessive screen time or other environmental factors. The frequency of blinks can change as well depending on what a person is doing: it’s more frequent while driving than while watching television; more frequent at night than during the day; and more frequent if someone has just woken up than if they’re about to fall asleep.
7) How many miles you will walk in your lifetime
An average person will walk around 700,000 miles during their lifetime. People who live in rural areas may only walk about half that distance. This is because people tend to travel less when they are close to home. When traveling by car, we usually use the foot pedals of the car to push on the gas or brake pedals. On a bike, we use our feet for balance and might use them for propulsion too.
8) How many bones you will have in your lifetime
You are born with 300 bones in your lifetime you will lose 206 of them. You will also go through 4 sets of teeth from the time you are a baby until you are an adult. Humans have more than enough teeth to replace all the ones we lose, but at some point it becomes less about having enough teeth and more about how well they work.
