Human Body 101 | National Geographic


The human body is a complex network of cells tissues and organs that together Make life possible Ten major systems are responsible for the body’s functions skeletal muscular cardiovascular nervous endocrine lymphatic respiratory digestive urinary Reproductive The skeletal muscular cardiovascular and nervous systems in particular create an infrastructure that facilitates the other systems the Adult skeletal system is a framework of over 200 bones They hold the body together give it shape and protect its organs and tissues The skeleton also provides anchor points for the muscular system, which includes three types of muscles skeletal smooth and cardiac They are found throughout the body and facilitate movement Nestled within these muscles is the cardiovascular system a pipeline that includes the heart blood vessels and the blood itself also called the circulatory system the cardiovascular system delivers oxygen white blood cells hormones and nutrients throughout the body Lastly the nervous system is a communication network of nerve cells that the body uses to transmit information and coordinate bodily functions It’s comprised of the brain the hub of sensory and intellectual activity the spinal cord And the many cranial and spinal nerves that emanate from them This infrastructure created by neurons blood muscles and bones Allows three other systems to regulate the body’s environment the endocrine lymphatic and urinary systems The endocrine system is a series of glands that use information carried by the nervous system to help regulate the body’s processes Thanks to this neural connection endocrine glands such as the thyroid are aware of the amount of hormones and other chemicals They need to produce these chemicals are then distributed throughout the body by way of the cardiovascular system the cardiovascular and nervous systems are also utilized by the lymphatic system a collection of lymph nodes and vessels that help regulate the body’s defenses Also called the immune system the lymphatic system uses neural pathways to transmit information About affected areas of the body and then sends out healing agents like white blood cells via the blood stream Another key, regulatory system is the urinary system, which includes the kidneys ureters bladder and urethra The urinary or renal system maintains the body’s electrolyte levels and filters wastes from the blood This waste is sent through the blood vessels into the kidneys and then expelled as urine All of these systems require energy to function and that’s where the respiratory and digestive Systems come in The respiratory system is a group of passageways and organs that extracts life-giving oxygen from the air we breathe Air enters the body through nasal cavities travels down the throat and is then transported to the lung The lungs extract oxygen for the body to use and then expel a carbon dioxide by-product when we exhale energy Can also come in the form of food? The digestive system is an approximately 30 foot series of organs that convert food into fuel Food enters the system through the mouth then moves into the esophagus the stomach and the intestines Nutrients are absorbed into the body while solid waste is expelled through the anal canal the end of the digestive tract No matter the roll size or shape of any of the body systems each began with a reproductive system This system is responsible for creating life the primary organs involved differ between the sexes with ovaries fallopian Tubes the uterus and vagina found in women and testes and a sperm channel found in men together Fertilization may occur organ systems form and then a child is born Humans are complicated organisms But when our 10 major organ systems are healthy They ensure our well-being You

    Even a doctor hardly specialists in more than one field just thinks,thanks the creator.

  5. Quick fact – it's not 200+ it's 206

    And another fact a baby has 300+ bones because most bones which are now one where double and join as the toddler grows up.

    Like if you impressed your friends with my facts XD

  6. i got an exam tomorrow.. thank you natonal geographic 😉 ths is awesome. Short and informative. plz make more about fat chains, kromosones etc 😉 this is really helpful

  7. What is the chance that this interconnected perfect human body system came together by a mere coincidence. Atheists mentality!!

  8. Loved that woman at the end of the video a beautiful combination of masculine and feminine attributes

  9. Joke: This looks like a presentation for Aliens to create a “Matrix” and some sort of “living beings”

  10. This video is incredible! It was concise but informative, interesting yet engaging. Thank you so much for this! It has helped me a lot.

  11. When you thought you'd pass your anatomy exam when you saw "human anatomy 101" and this is high school anatomy 😭

  12. What's up with all these religious people praising god in the comments? Thought this was just about the human body

  13. Great Video, highly appreciable.
    I know, It takes a lot of time (sometimes days) to produce a single video like this, but the effort is worth it. And so, the information provided in the video is crisp clear and is equal to the many lectures provided at school or coachings.

  14. I have a question. How do we know what hunger is?

    Not the symptoms.
    Or what our brain tells us.
    But. How did we discover it?

  15. The human body has many organs, 206 Bones and baby has 300 bones, More than 200 organs, 90 muscles and 87 muscles, am i right??

  16. WUT???????

    I'm watching this video and thinking:
    Everything I learnt in life is completely wrong.

    WHY SCIENCE TEACHERS?????
    WHY DO YOU HAVE TO BE SO COMPLICATED?????

  17. The body is probably one of the most complex but mysterious. It is amazing that organs in our bodies are connected organically so that humans can survive. If I become a life scientist, I want to study more about human body.
