Random Facts About the Human Body

There are so many interesting and amazing facts about the human body! Discovering these intriguing tidbits will teach you more about our anatomy while wowing your friends with knowledge!

Babies do not have kneecaps and their cartilage will gradually transform into bone as they get older. Each individual is uniquely imprinted with fingerprints and tongue prints, taking about 12 hours for digestion of one meal.


Bones play an essential role in shaping us, keeping us upright, protecting organs, storing minerals such as calcium and phosphorus, and providing shape. While bones may appear non-living, they actually contain living tissue which continually remodels and reshapes itself throughout your lifetime. In addition, bone marrow provides new blood cells.

Human bodies contain 206 bones, such as those in the skull, face, ribs, sternum and pelvis. Some of these 206 bones fuse together during gestation and childhood to form long and short bones – this explains why infants typically have less bones than adults do.

Some of our larger bones, like those in our arms and legs, feature five individual bones while fingers and toes each have three. If you’re picking up something heavy, remember that your wrist, hands, and fingers collectively have 54 bones ready to grab and secure it!

Appendixes have become notoriously malignant over time, becoming sources of infection to other parts of our bodies if left alone. Yet they serve an essential purpose – they store microbes that promote gut health. Therefore they serve an integral role in digestive systems.


The human eye is an incredible organ that provides us with vision of the world around us. Understanding its various parts is crucial if we’re to use them effectively; not only do our eyes give us access to what’s going on outside, they can also relay information directly into our brains for processing and interpretation.

The outer layer of our eyes, known as sclera (say: SKLAIR-uh), serves to protect them from damage and infection by being thick and tough, with blood vessels carrying oxygen into our eyeball. Directly behind it lies an opaque lens called cornea (say: KOR-nuh). This transparent lens lets light pass through it, helping focus objects as it travels toward our retina at the back.

Light passes through the cornea before landing on a dark area at the back of the eyeball known as the iris, where it meets an adjustable hole called a pupil which allows eyes to respond to different lighting conditions by widening or narrowing depending on environmental light levels. Furthermore, this area contains colored pigment that gives eyes their characteristic hue.

There are six muscles that assist with eyeball movement: medial rectus, lateral rectus, superior ophthalmic muscle, inferior ophthalmic muscle and sphenoid bone. Our optic nerve provides visual information directly to our brain, with our eyes being capable of detecting movement up to 2.5 light-years away and blinking 20 times per minute or 10 million times annually – our appendix even stores microbes beneficial to digestion!


Human and other animal faces feature prominent noses which serve several essential purposes. Breathing air through, smell of scenting food and tasting is all accomplished through this complex structure made up of bone, cartilage and fat that contains nasal septum, turbinates and sinuses; additionally it also houses small muscles for facial expressions.

The nose serves three main purposes: providing oxygen, protecting against dirt and serving as the sense of smell. Air is brought into the nostrils through nostrils where it warms and moistens before being passed to lungs for filtering; additionally it serves as an outlet to release old air that has built up within us.

Furthermore, it protects our eyes by filtering out harmful ultraviolet rays from the sun and other sources of ultraviolet light. Furthermore, its mucous membrane vibrations act like an air stethoscope, helping us hear heartbeats and other sounds within our bodies.

Crookedness in a nose may result from either an off-kilter septum, an injury to bone spurs or some other factor. Crooked or deviated septum makes breathing difficult and leads to nasal congestion; additionally, thin tissue inside of it secretes sticky mucus to clean off dust and other contaminants from entering through its thin passageways.

Your sense of smell allows us to taste food by picking up on aromas from foods we consume; our noses can detect up to 100 different odors! In our lifetimes we produce enough earwax to fill two swimming pools, blink 20 times every minute (ten million per year!), and stop growing after puberty whereas noses and ears continue to expand throughout our lives.


The mouth is an integral component of human anatomy. It plays an integral part in food intake and digestion as well as speech production and respiration. Its oval-shaped opening starts at the lips and extends towards the tonsils; composed of lips, cheeks, hard and soft palate, tongue, ducts of the salivary glands, etc.

Salivary glands produce saliva (spit) to aid with breaking down starches in our food, and tongue use this fluid to move food down through throat, esophagus and stomach for digestion. Furthermore, tongue also contain small papillae which act as taste buds on its surface.

Estimates suggest we blink approximately 20 times every minute – that equates to 10 million times in a year!

Babies blink twice as frequently as adults due to the development of their eyes; this helps ensure they see properly.

Human bodies contain approximately 25,000 quarts of saliva – enough to fill approximately two swimming pools! We produce billions of cells every day; should any become cancerous, this could result in our deaths.

If you suffer from chronic health conditions, salivary glands can stop producing saliva altogether and lead to dehydration and digestive bloating. To counteract this effect, drinking plenty of water will keep salivary glands working effectively while using a humidifier will increase body fluids which will also help alleviate discomfort and make you feel more at ease.


Human beings utilize specialized organs to sense both external environments and internal states through various senses. People typically identify five senses – touch, taste, smell, sight and hearing. But the number can depend on your definition of each sense and what sort of information each sends directly to the brain.

Sensory receptors are cells which convert information from their environment into electrical signals that the brain can recognize and interpret. Each sensory receptor is tailored specifically to collect certain types of information before sending the signals along to our brain, which then transforms those signals into perceptions about our environment and body.

Humans generally deem vision to be the most vital sense, since it provides us with the most information per second. But with so much overlap between each sense’s information collection capabilities and those collected by another sense, some experts consider there may be as many as nine or more senses in a healthy human.

No one seems to notice what our bodies are sensing most of the time, yet that doesn’t mean we don’t use our senses – whether that be through using your favorite pen or roller coasters and how your brain processes these experiences or by keeping yourself calm during stressful moments on an airplane ride – yet every day, these experiences use your senses without even realizing it – hence why taking care of our senses should be prioritized and scheduled a free consultation session with a BetterUp coach is so vital!
