Metabolism & Nutrition, Part 1: Crash Course A&P #36

Metabolism is a complex process that has a lot more going on than personal trainers and commercials might have you believe. Today we are exploring some of its key parts, including vital nutrients — such as water, vitamins, minerals, carbs, fats, and proteins — as well as how anabolic reactions build structures and require energy, while catabolic reactions tear things apart and release energy.

    anybody notice that when he was explaining the percentages of the body, he basically the body is full of 101% of stuff (64+16+16+4+1=101)

    If you sneeze during this video, you just missed 40 bullet points.

    Live this vídeos but this guy talks way to fast for all that information. I wish this video had a slow down feature like the audio books 😂 other than that I think is great!

  6. Полина Буднева on November 16, 2020 at 9:14 pm

    It is the best channel I’ve ever seen! I’m saying ,,thank you" very loudly. Sooo many interesting topics (physiology, history, economics, art, o my God!) explaned in a beautiful and easy-to-understand way…It is a dream. Thank you, thank you!

  7. The_White _Lion on November 16, 2020 at 9:16 pm

    This was incredibly helpful. Thank you so much, Crash Course!

    I absoultely LOVE your videos, but while I love that you can speak this fast, and you clearly love yourself for speaking this fast, I geniunely have a headache so I put you on .80x speed and you almost talk normally. Now I typically put videos on 1.5x speed because they are boring and share next to zero information, but you can’t possibly expect anyone to follow a biology lecture at 1.5x speed just because you sound cool and have the capacity to speak this fastly. Fun fact, the reason we love using chalk and black board still in pure maths lectures is because it’s still the best way to digest information. The speed it takes you write something down is almost around the speed it takes the brain to process that new information, so slinding like a maniac through slides and speaking as if at gunpoint, is kind of against the purpose of education here, isn’t it ?!

    man you figure if you can understand so many parts of the body you would evolve to have functioning eyes that dont require every one of your infographics to proudly sport glasses on the cartoon character. way to normalize blindness while promoting health & evolution. Maybe we were better off when we didnt understand ourselves and actually were manly. Now thats some food for thought! Life is short, you learned too much, and now you are a wet noodle.

  10. peach1995 on November 16, 2020 at 9:18 pm

    ok dude, so what should i eat(or not to eat) to loose weight?.. from scientific point of view..

  21. Barbara Frydrych on November 16, 2020 at 9:31 pm

    Jesus! I think he needs to catch a bus that’s why talks so fast 😀 it would be amazing video, but way too fast to translate and understand at the same time 😀

  22. D D on November 16, 2020 at 9:32 pm

    Play at 0.75 speed. He sounds an educated drunk

  23. Rumali Chamathka on November 16, 2020 at 9:33 pm

    The colors in this room do great things for his skin tone.

  26. Bolog on November 16, 2020 at 9:37 pm

    Don’t get me wrong, I’m an outsider looking in, but I’m wondering how you build or maintain, or even affect your metabolism? I’ve noticed mine is pretty effective and I wanted to know why. I was just a simple soul looking in on things I didn’t understand.

  27. Sue's Journey on November 16, 2020 at 9:38 pm

    So much information in this video.. I think I retained about 1/4 of it.. but it’s a start. I always wondered what metabolism actually was.

  28. oumaima si on November 16, 2020 at 9:39 pm

  39. Jonathan Kardonski on November 16, 2020 at 9:56 pm

    Umm, how about ketones to produce atp? And maybe excessive polyunsaturated fatty acids from plants are actually like a toxin bc our body don’t use them as much and they can’t be burned off without causing damage to the mitochondria. You’re very enjoyable Hank Green.

  47. Katrin Sinyagina on November 16, 2020 at 10:06 pm

    am i the only one plays this on a slower speed?

  48. LYNAY LGWAYH on November 16, 2020 at 10:07 pm

    im curious of calories and what our bodies pick up of it. is there some difference in our digestive systems that doesnt absorb all of the available glucose? so example two people eat a 300 cal burger, could one of us have a less effecient system that let it out in our feces so that i would be consuming 200 cal but my friend with a better digestive system gets the whole 300?
    im particulary thinking of corn how it has a tendency to skip through our digestive system.. food doesnt always seem 100% digested… ie. i didnt absorb all of the calories that i ate.
    now could this affect how people are more skinny while eating more? is there some scientific papers on this topic?

  49. Azul Seoane on November 16, 2020 at 10:07 pm

    odio la cuarentena
