Lymphatic System: Crash Course Anatomy & Physiology #44

Lymphatic System: Crash Course Anatomy & Physiology #44

Today Hank explains your unsung lymphatic system and how it supports cardiovascular function by collecting, filtering, and returning interstitial fluid back into the bloodstream via a system of lymphatic vessels. He also explains the system’s major role in fighting off infection, and how lymph nodes, other lymphoid organs, and MALT areas house antigen-attacking lymphocytes that provide crucial support to the immune system.

    this guy never explains what the topic is. He just shows of his grammer skills with science. Common lets be frank, no one ever learns from this jack

    Whether we are in sleep or awake, the sound of music or talk broadcast from a radio must activate our brain causing some blood circulations in our brain. Assuming this is true, while we are in sleep, our lymphatic pathways doing over-night cleanup seems to be partially obstructed if we keep radio on at night while we are sleeping. This seems to suggest radio during sleep is a bad idea. Please comment. Thank you

    And when we eat 24/7 and have tons of heavily processed foods, this system slowly gets clogged and backs up toxins and waste, eventually creating diseases and health complications.

  11. oriana garrido on July 26, 2022 at 3:33 am

    Can you believe that at Biology class we were never taught the lymphatic system?
    Digestive, Nervous, Respiratory, Cardiovascular… everything… except Lymphatic…
    Why?

  12. Hi There on July 26, 2022 at 3:35 am

    4:05 I love how the capillaries dance!

  13. marshal on July 26, 2022 at 3:39 am

  14. Ibs on July 26, 2022 at 3:39 am

  15. Rita Hall on July 26, 2022 at 3:41 am

    Is lymphatic system responsible for inability to sweat – Also how does auto immune disorders connect with lymphatic system specifically Hashimotos ?

  16. Sony S on July 26, 2022 at 3:42 am

    stupid

  17. Forever Young on July 26, 2022 at 3:44 am

  20. Raquelfitpt on July 26, 2022 at 3:48 am

    What about when someone has there tonsils removed due to re-occurring tonsillitis? Does this impact the rest of the lymphatic system in any way?

  21. imdad ullah on July 26, 2022 at 3:50 am

  22. amantha0 on July 26, 2022 at 3:50 am

  27. Larry Bryant on July 26, 2022 at 3:59 am

    Really appreciated, Hank! Haven’t IGNORED the importance of taking care of my lymph system since graduating nursing school in 93’…

  28. Qanaty on July 26, 2022 at 4:00 am

    Subhana Allah! This is precise & smart technology in us!

  29. Liz Kanyambu on July 26, 2022 at 4:01 am

    Damn annoying

  36. Marwa Mirgani on July 26, 2022 at 4:10 am

    Thanx to you I finally understand what a lymph is

  37. SAGNIK BALA on July 26, 2022 at 4:10 am

    I am watching these from 2019 and it always cleared all my problems

  38. Margreeth Bangert on July 26, 2022 at 4:11 am

    Nice video. One question, why is the right side of the symstem smaller than the left?

  39. Adrian Somogyi on July 26, 2022 at 4:12 am

    I had no idea that so much fluid recovery is done by the lymphatic system.

  40. goldenegg on July 26, 2022 at 4:12 am

    I understand its a crash course but you moved/spoke way too fast. Crash course hits major/important points without going into all the details, doesnt necessarily mean speak and give a lot of imformation really fast. Had I not already known some of the terms and what goes on, I would’ve been utterly and completely lost.

  41. Kyra Nolen on July 26, 2022 at 4:12 am

    what are the two other main parts of the lymphatic system apart from Lymph?

  42. Mow Time on July 26, 2022 at 4:13 am

    To fast

  43. Elizabeth Leaf on July 26, 2022 at 4:13 am

    Sir, I just met you but I think I’m in love with you. 😹 I was having such trouble really grabbing this information and the other video I watched did nothing for me. This 9:20 minute video helped me so much! Ready to really study my notecards now that I have a basic understanding.

  44. autentyk on July 26, 2022 at 4:14 am

    04:05 it’s vs its. With all the appalling mistakes that have been happening in the last few videos, this series is the last thing I was expecting to hit the illiterate bingo.
    How the hell did it happen? Why did that person who typed all this stool get the job in the first place?

  45. Pascale on July 26, 2022 at 4:14 am

    Your information is great.. BUT please slow down. Its a school zone, lets drop the speed to 40km oppose to 110

  46. Alicja on July 26, 2022 at 4:15 am

    Video starts 2:10

  47. Kate Sleath on July 26, 2022 at 4:17 am

    Hi CrashCourse! Do you have a reference for where you read that there are 600-700 lymph nodes in the body? Thank you!

  48. Kinirin on July 26, 2022 at 4:17 am

    You got me to pass my first pick highschool exams thanks.

  49. Eclectic Interests on July 26, 2022 at 4:20 am

    Shoring up our Immune System.

  50. Lauren Poole on July 26, 2022 at 4:21 am

    Love the comparison of the lymphatic system to security! It’s funny how a simple analogy can make information that seems overwhelming more relatable and less daunting. Thank you! 🙂
