Weird Did You Know Facts About Your Body
Human bodies are astounding machines; each part functions together like an orchestrated city to ensure we remain healthy and alive.
Explore interesting body facts related to bones, skeletons, eyes, muscles, blood circulation and the brain! From little known information to trivia that will impress both children and adults alike! These intriguing details will keep them entertained for hours!
Bones
Bones provide your body with its shape, help you move freely, and safeguard vital organs. In addition, bones are living tissues which means they grow and change with you over time, just like everything else within it.
Your bones are composed of hard proteins called collagen (pronounced KAN-sil-uh) and calcium phosphate, two minerals found in nature that store and release energy when necessary. Ligaments bind bones together at joints like strong rubber bands.
The outer part of bones is known as the periosteum (pronounced: pare-ie-OST-tee-um). This dense membrane contains nerves and blood vessels. Meanwhile, inside is compact bone that appears ivory-colored and extremely hard; it features holes that carry blood vessels and nerves.
Your body has 206 bones that comprise your skeleton. Each one has a distinct form. For example, one bone which supports your eyeball has an eye socket to allow the bone to break instead of your eyeball in case of accidental impacts to help preserve vision.
Muscles
Your muscles help your body move, as well as serve several other important purposes. They’re made up of soft tissue with thousands of tiny fibers that stretch and press together; these store and release energy, providing your heart a way to pump blood around.
Your body has over 600 muscles located throughout, all connected by connective tissues like ligaments. Together these form your musculoskeletal system.
Certain muscles, like those in your arms, can easily be seen. Others – including those of the stomach that help digest food – remain more concealed.
The body contains three types of muscle tissue, namely skeletal, smooth, and cardiac. There are also some specialized muscles such as the obliques (pronounced: oh-BILE-sees) in your buttocks and diaphragm (pronounced DAH-frum) in the chest area; quadriceps muscles of legs become particularly visible during physical activities or sports games.
Eyes
Eyes take in vast amounts of information about shapes, colors and movements around us that is relayed directly to the brain so we can stay aware of what’s going on around us.
Eyes are approximately the size and shape of a ping-pong ball, nestling into small openings called eye sockets in our skulls. Their white part, called the sclera, protects them and provides necessary drainage from inside to out.
Blinking causes tears to form in your eyelids and wash away germs and dust that might get in, while glands at the outer corners of each eye produce the clear liquid known as tears. No two people have identical eye colors or shapes – just like fingerprints! Each set of eyes are completely unique to themselves! I think that makes yours all the more special!
Nose
The nose allows us to smell and tastes food. Additionally, it acts as an entryway into your respiratory system by warming and filtering air before entering your lungs.
Your main nasal structure, known as the septum (say: SEP-tum), consists of an internal wall known as the septum that separates each nostril. Constructed from firm cartilage (KAR-tel-ij) and bone, its surface is protected by a mucous membrane for comfort.
Crooked septums may be caused by either an excess of cartilage, or spurs, on either the right or left side of nasal passages. Cilia line the septum’s surface, helping move mucus out of sinuses and back into nose, as well as detect smells such as smoke or food that has gone off-taste – sending this information straight into your brain, so it can assess whether something is beneficial or detrimental.
Taste
From bone regeneration to miles of blood vessels, the human body is packed with extraordinary features. Use these shocking yet interesting facts about brain, skin, eyes, heart, blood vessels and more to introduce children to anatomy while providing fun learning through interesting information. Create a fun trivia game or use these cool facts as quiz questions against friends’ knowledge – your brain uses 25% of all oxygen breathed while taste buds change as we age!
Lungs
Your lungs provide oxygen to your blood and remove carbon dioxide, acting like soft, light organs in your chest. Healthy lungs have pinkish-gray hue, while diseased ones appear darker gray with black spots present.
Starting in the trachea (TRAY-kee-uh), air flows down through to reach the larynx or voice box at the back of your throat. There, it divides into 2 tubes known as bronchi (BRAH-chi), each branching off into smaller tubes called bronchioles that lead directly into small air sacs called alveoli (al-VOH-lee-olz).
Your lungs contain hundreds of millions of alveoli that resemble small grape clusters or micro balloons, allowing oxygen to easily pass between their walls due to being lined by thin squamous epithelial cells that produce surfactant; this substance makes breathing easier by expanding lung capacity during inhalation and exhalation.
Teeth
At our cores we may not be eating brains or wandering dark corridors at night, but our bodies are just as strange and wondrous as anything that goes bump in the night! From miles of blood vessels to our ability to regenerate bones, they offer incredible features which children will love learning about with this fun body facts collection featuring weird did you know facts, crazy trivia and amusing truths related to bones, skeletons, muscles, eyes, taste buds, blood and much more.
Your skeletal system contains about 206 bones and it requires more muscles to frown than to smile. Our blood cells carry oxygen throughout our bodies while bone marrow creates red and white blood cells. All these body parts work together as organ systems to keep us healthy, just as cities need departments in order to operate smoothly.
