What’s happening inside your body? Have you ever wondered how little we know about our bodies the human body is an amazing and unique machine? That triggers thousands of processes every second and we’re not aware of a single one Today, we’re about to look at all the processes that are going on in the very depths of man You may say which man well, what about that one? We can see he is in bed some ordinary person, just like you or me it’s 8:00 a.m. And I guess he is going to wake up soon, so it’s better we hurry What is the easiest way to get in the nose of course wow? It’s really dark in here And we see a vast forest around as you can guess its nose hair this hair catches all the dirt viruses and toxins Until he blows them or sneezes them out an interesting fact People who live in cities have more hair in their noses than those who live in the countryside, and it’s thicker and stiffer It’s a vital air filter for the human body, so we have to try really hard to break through them hurry up We don’t want to be sneezed out jump and we Were falling down the NasoPharynx wait a second? What’s that strange sound? Can you hear it? It’s coming from somewhere near the mouth we better stop there and check this out Aha, he’s just gnashing his teeth 8 to 30% of people around the world gnashed their teeth while sleeping it’s called Bruxism compressing the Jaw Bones is an evolutionary Instinct of homo Sapiens who use their teeth as a weapon against predators These days people clench their teeth while sleeping as a reaction to negative emotions such as fear Anger or disappointment Well, I hope this guy isn’t depressed or something and don’t worry about those tiny things you see They’re just bacteria. There are about 40,000 Bacteria in the human mouth and most of them aren’t harmful Also, Saliva always cleans the oral Cavity and protects teeth from damage yep It’s that liquid stuff around It’s funny an average person creates so much saliva during their life that it can fill two swimming pools Yeah, I can’t imagine what it would look like oh His breathing changed and became faster and the gnashing has also just stopped She’s waking up Let’s head back to the NasoPharynx the air passing through the nose becomes cleaner and warmer here Then it goes through the larynx to the trachea as you can see the trachea is a Tube that consists of cartilaginous rings Towards the end it branches into the bronchi through which the air reaches the right and left lungs You can see each of the bronchus branches into thin tubes with pulmonary vesicles at the end That’s where the blood gets oxygen and gives off carbon dioxide by the way an adult person performs around 23,000 inhalations and exhalations a day Impressive, huh oops. It seems. We’ve been detected. He’s going to sneeze See how the lungs just filled up with air when sneezing the speed of Airflow reaches 60 miles per hour So we better get out of here before we fly out like a rocket from his mouth Let’s jump into the capillaries and give the circulatory system a little visit the circulatory system is a long labyrinth in twining the entire human body The total length of all the blood vessels is about 62,000 miles or 100,000 kilometers, this is twice as long as the length of the equator can you imagine? the blood filled with oxygen is heading to the left side of the heart through the pulmonary vein Then the heart pumps it to the other parts of the body to provide oxygen to the muscles Did you know that our heart pumps around? 182 million Litres of blood during our lifetime It pumps blood at such pressure that it could raise blood up to the fourth floor of a building And it is very small just about the size of your fist. Oh His heart started beating much faster what but let’s go a bit higher and see what he is doing Hmm. I can see the bathroom his kitchen the bathroom again Seems like he’s in a hurry. He’s running around his apartment like a rabbit you might be thinking. Why is everything upside down Well according to physics the collective lens reverses the image of the object The Cornea and lens are pretty much collective lenses so they invert the image when it reaches the retina of the eye after That the image is transmitted to the brain along the nerves and the brain flips it back to how it really is By the way the only part of the body that has no blood supply is the cornea of the eye Yeah, that one. It receives oxygen directly from the air wait a second Something is ringing around this phone. I guess where is it ah? It’s his boss collar you believe that you’re special his eyes are expanding down and pimples are dilating it seems He’s nervous and scared Also, the more the brain works the larger the pupils become he’s probably trying hard to come up with something to tell his boss Let’s hurry to the ears. I want to hear what it’s going to happen uh-oh It seems as boss has gone wild well. It’s already 9:00 a.m.. And this guy is still at home You can hear how loud the boss is screaming and see how the ear drum is vibrating the ear is a unique human device There isn’t any other mechanism that responds to the smallest changes in air pressure with such striking accuracy It transforms the vibrational motion of the sound wave into a certain sensation Which our brain perceives as sound? Speaking about the brain let’s pay it a visit as well 100,000 chemical reactions occur in our brain every single second every second It’s simply amazing isn’t it as we can see wernicke’s area and broca’s area are active right now Both of them are located in the left hemisphere of the brain and participate in the speech function For Nicky’s area is responsible for understanding speech and broca’s area is responsible for Reproducing speech also it controls the muscles of the face tongue and throat I guess the guy’s explaining Why he is late to his boss? Wait a second something else is happening. Why is he shaking oh man, no? He’s choking didn’t he learn that he’s not supposed to eat while talking let’s get to the nasoPharynx quickly Maybe we can help him in some way When a person swallows the larynx usually closes in order to prevent food from getting into the respiratory tract But while talking the larynx might remain open oh my judging by the smell it’s a piece of fried eggs with bacon He’s coughing now. Don’t worry man. You can do it Coughing is just a natural attempt by the body to remove anything stuck in the respiratory tract You must coff harder now great there He’d go that annoying piece flew out so alas we can’t see the digestion process today. No worries We’ll come back another day and show it to you in another video. So our friend is hurrying to work Let’s leave him alone and come back here another time lots of amazing Processes going on in the human body are still uncovered how do our cells form and get replaced with others How many enzymes are active in the body how many Bacteria do live inside of us and why we’ll answer all of them So thank you for joining me on this adventure Around the Human Don’t forget to hit the like button below the video and click subscribe new discoveries are waiting for you
