The human body is a fascinating and complex machine, constantly working to keep us alive and functioning. Despite living with our bodies every day, there are still many surprising and intriguing facts that we may not be aware of. From hidden senses to incredible healing abilities, our bodies are full of astonishing secrets waiting to be discovered. Get ready to explore 14 things you didn’t know about your own body, and prepare to be amazed by the wonders within.
You Have A Third Eyelid
Did you know that you have a third eyelid? It’s called the plica semilunaris, and it’s a small fold of tissue located in the inner corner of your eye. This vestigial structure is a remnant of a larger, more functional third eyelid found in some animals, such as birds and reptiles. In humans, the plica semilunaris helps to produce and distribute tears, keeping your eyes lubricated and healthy.
Your Ears And Nose Never Stop Growing
While the rest of your body stops growing after puberty, your ears and nose continue to grow throughout your entire life. This is because the cartilage in these structures continues to produce new cells and expand gradually over time. The changes are subtle and occur slowly, but by the time you reach old age, your ears and nose may be noticeably larger than they were in your youth.
You Have Taste Receptors Beyond Your Tongue
When you think of taste, you probably think of your tongue. However, did you know that you have taste receptors in other parts of your body too? These receptors can be found in your throat, intestines, pancreas, and even your lungs. While their function in these areas is not fully understood, researchers believe they may play a role in digestion, metabolism, and respiratory defense.
Your Body Produces Enough Saliva To Fill Two Swimming Pools
Over the course of your lifetime, your salivary glands produce an astonishing amount of saliva – enough to fill two swimming pools! Saliva plays a crucial role in maintaining oral health, helping to neutralize acid, remineralize teeth, and fight off harmful bacteria. It also aids in digestion by breaking down food and making it easier to swallow.
You Have A Unique Tongue Print
Just like your fingerprints, your tongue print is unique to you. The surface of your tongue is covered in tiny bumps called papillae, which create a distinct pattern that is different from everyone else’s. Some researchers even suggest that tongue prints could potentially be used for identification purposes, similar to fingerprints.
Your Bones Are Stronger Than Steel
Pound for pound, your bones are stronger than steel. This incredible strength comes from the unique structure of bone tissue, which is composed of both hard mineral crystals and flexible collagen fibers. This combination allows your bones to withstand significant pressure and stress without breaking. In fact, a single cubic inch of bone can support up to 19,000 pounds of weight.
You Have A Second Brain In Your Gut
Have you ever had a “gut feeling” about something? Well, it turns out there might be some truth to that phrase. Your gut contains a complex network of neurons, often referred to as the “second brain” or the enteric nervous system. This system can function independently of the brain in your head and plays a crucial role in digestion, immune function, and even mood regulation.
Your Body Regenerates Itself Constantly
Every day, your body is working hard to regenerate and replace old cells with new ones. The lining of your intestines regenerates every 2-4 days, your skin cells turnover every 2-4 weeks, and your red blood cells are replaced every 4 months. This constant renewal process helps to keep your body functioning optimally and repairs damage caused by stress, injury, or disease.
You Have A Powerful Healing Ability
Your body has an incredible capacity to heal itself. When you get a cut or a scrape, your blood clots to stop the bleeding, and your immune system jumps into action to fight off any potential infections. Over time, new cells grow to fill in the damaged area, and the wound heals. This same process occurs on a larger scale when you break a bone or recover from an illness – your body works tirelessly to repair and restore itself to health.
You Have A Superhuman Sense Of Smell
Your sense of smell is more powerful than you might realize. Humans can distinguish between more than 1 trillion different scents, making our sense of smell far more sensitive than that of many animals. In fact, some researchers believe that our sense of smell plays a significant role in memory, emotion, and even mate selection.
You Produce Enough Carbon Dioxide To Fill A Tree
Every day, through the process of respiration, your body produces approximately 2 pounds of carbon dioxide. Over the course of a year, this adds up to enough carbon dioxide to fill a 30-foot tall tree. While carbon dioxide is often thought of as a waste product, it plays a vital role in regulating blood pH and is used by plants during photosynthesis to produce oxygen.
Your Body Is Home To Trillions Of Microbes
Your body is not just made up of human cells – it’s also home to trillions of microbes, collectively known as the human microbiome. These bacteria, fungi, and viruses live on your skin, in your gut, and in other parts of your body, and they play a crucial role in maintaining your health. They help to digest your food, train your immune system, and even produce vitamins and other beneficial compounds. In fact, the microbes in your body outnumber your own cells by a factor of 10 to 1!
You Have A Built-In Cooling System
When your body temperature rises, whether from exercise, fever, or hot weather, your built-in cooling system kicks into gear. Your blood vessels dilate, allowing more blood to flow to the surface of your skin, and your sweat glands release sweat onto the surface of your skin. As the sweat evaporates, it cools your skin and helps to regulate your body temperature. This incredible system allows you to maintain a consistent internal temperature, even in extreme conditions.
You Have A Remarkable Capacity For Learning And Adaptation
Your brain is an incredible organ, with a remarkable capacity for learning and adaptation. Every time you learn a new skill or piece of information, your brain creates new neural connections and strengthens existing ones. This process, known as neuroplasticity, allows your brain to change and adapt throughout your entire life. Whether you’re learning a new language, mastering a musical instrument, or simply exploring a new hobby, your brain is constantly growing and changing in response to your experiences.
