10 Fun Facts About Your Body (That You Might Not Know)

Introduction

You might be surprised at how much your body does every day. In this article, I’m going to share 10 facts about the human body that are pretty mind-blowing. So put on some comfortable clothes and get ready to learn something really cool!

1. You are taller in the morning than you are at night.

While this might seem like a strange thing to learn, it’s actually true! When we wake up, our bodies have more water because they soaked up some over night; this causes us to be taller. The reason for this is that our bodies have about 60% water in them—and when we’re dehydrated or have low levels of salt and sodium, we retain fluid and grow shorter. On the other hand, when we drink large amounts of fluids (such as coffee!) during the day or eat salty foods that make us lose fluids through sweat, we’ll shrink back down again! So if you want to look tall all day long…drink lots of coffee and eat lots of chips (not recommended—but still).

2. Your ears and nose never stop growing.

If you’ve ever wondered why your ears and nose keep growing, it’s because they’re not the only things that do.

People’s bodies are constantly changing from day to day, but those changes usually come in small increments. Your cells are continuously being replaced, and while your body may be able to handle a little extra hair here or there, some growths like your ears and nose will go largely unnoticed (unless you’re really paying attention).

During the hours of restful slumber that take place between dusk and dawn, various processes take place within our bodies. Our hearts beat slower than usual while we snooze away; our blood vessels expand to allow oxygenated blood flow through more easily; and even our breathing becomes more shallow as compared with our daytime activities. These changes all contribute toward making sleep feel so good: The muscles relax after a long day of work or play; maybe we dream about something involving waterfalls or sharks; maybe we just wake up feeling refreshed instead of tired as hell after another stressful day spent binge watching

3. Your heart is the strongest muscle in your body.

Your heart is a muscle, just like the ones in your biceps or calves. But unlike those little guys, your heart never gets tired. It’s the only muscle that works nonstop and never gets tired.

Why? Because it’s already at its strongest! Your heart has two jobs: to pump blood throughout your body, and to make sure all of the parts of itself stay healthy so they can do their job better. That means you need to take care of yourself if you want to keep getting stronger every day.

4. The human brain is made of 60% fat (which is why it’s so important that we eat well)

The human brain is made up of 60 percent fat. “This is why it’s so important that we eat well and take care of our brains,” Dr. Ryan explains. “It’s really the most powerful organ in the body and it needs a lot of nutrients to function properly. Our brains are also very sensitive to what we eat; studies have shown that even if you just have a little bit too much sugar or caffeine, it can affect how well your brain functions.”

Another interesting fact: Your brain cells communicate with one another through electrical signals, which means they need water to function properly as well! This is another reason why drinking plenty of water every day can improve your mood and help prevent dehydration-related illnesses like headaches (and hangovers).

5. The surface area of a human lung is equal to a tennis court.

Did you know that the surface area of a human lung is equal to that of a tennis court? It’s true—our lungs are the third largest organ in our body, and they’re packed with vital organs.

Think about it: if you were on one side of a tennis court and someone was on the other side, each person on the opposite end would have their own personal space just like how each lung has its own special function within your body.

The surface area of your lungs alone is enough to keep air flowing through them at all times. It’s also enough space for more than 20 people to dance around wildly without stepping on each other’s toes (or feet).

6. Your eyes have over two million working parts.

Did you know that your eyes have over two million working parts? That’s a lot! The human eye is actually made up of three main parts: the cornea, lens and retina.

The cornea is the clear outer covering of your eye that helps focus light onto the retina. The lens focuses incoming light rays onto a single point on the retina, which then converts them into electrical signals that are sent to your brain. The retina contains rods and cones (light-sensitive cells) which send these electrical signals through the optic nerve to be processed by our brains.

So what do these three parts work together to do? They help us see clearly! Your cornea bends incoming light so it hits each part of your retina at just the right angle; this allows you to see clearer images without having to move around too much or constantly adjust how close or far away you are from something or someone else.

Your eyes also allow you not only see objects up close but also out in front of them too! That’s because they’re constantly taking in information from both near objects such as bookshelves and clocks on walls nearby all over again

7. In one square inch of skin, there are about 19 million cells.

One square inch of skin contains about 19 million cells. This is the same number of people who live in New York City, and your body sheds 5 million dead skin cells per hour. Your body also has 650,000 sweat glands that secrete water and salt to cool you off when you’re hot or working out.

The skin is the largest organ in your body—it covers every inch from head to toe, protecting all your other organs from harmful chemicals and germs. It helps keep us warm (through insulation) and cool (by sweating). It helps sense pain and touch; we can use our sense of touch to tell where something hot or cold is touching us because it changes how much our nerves send signals back to the brain when they come into contact with something different from their surroundings

8. The amount of bacteria in your mouth at any given time equals the world’s total population.

Your mouth is one of the most densely populated places on earth. In fact, there are more bacteria in your mouth than there are people on Earth. That’s a lot of mouths to feed!

The majority of these bacteria are good for you. They help break down food and fight off infection, but they don’t just have jobs—they also produce all kinds of proteins that keep us healthy, too.

9. Humans have about 300 bones at birth and 206 bones when we’re adults

Our bones are made of calcium and phosphate, which are found in our blood.

Bones are living tissue that grow and change shape as we grow. As we age, some of our bones fuse together to make the skeleton stronger and more stable.

There are two types of cells in bone: osteoblasts (the ones that make new bone) and osteoclasts (the ones that break down old bone). These cells work together to keep a healthy balance between creation and destruction so that we don’t have too much or too little. This process is called remodeling.

10. The largest cell in the human body is the female egg and the smallest is the male sperm.

You may already know that your body is made up of a lot of different cells, but you might not know that some of those cells are much bigger than others. The largest cell in the human body is the female egg—and no wonder it’s so huge! It has to keep all the essential molecules for life (like DNA and proteins) contained within one shell. The smallest cell is actually a sperm, which measures only 20-30 micrometers long (one micrometer is one millionth of a meter).

Bonus!!! Our bodies are incredibly complicated!

Our bodies are incredibly complicated, but there are some really cool facts about our bodies that you might not know. Here are a few of my favorites:

The human body is made up of over 7 trillion cells! That’s a lot of cells! Each cell in your body has its own function, and together they form organs like your heart or brain. Your skin cells work to keep harmful bacteria out, while blood cells help deliver oxygen throughout the rest of your body. Even though we’re all made up of different types of cells with different jobs, we all share the same basic parts (like bones).

People have different fingerprints because each person’s fingerprints contain individual patterns created by their unique mix of proteins in their sweat glands. Some people think fingerprint patterns can tell them things about their personality—and that may be true!

Conclusion

We have a lot of amazing things about our bodies and the way they work, but we also have to take care of them. We should try to eat well, exercise often, and get lots of rest. It’s important for us to remember these facts so that we can make sure we’re taking good care of ourselves!
