    3 hours of lecture and I am completely vexed; you do this in 15 minutes! Thank you so much Dr. Mike for getting me through A&PII!

    I’ve been struggling and frustrated to the point of tears in class the past two weeks trying to make sense of my professors lectures. How do you make more sense to me in less than 15 minutes than he has in 8 hours? You and Dr. Matt are amazing, you truly give me those *AHA!* moments when listening to your podcasts/watching videos. Please keep doing what you do!

    I am not a medical student and wasn't interested in how the body worked until I stumbled upon these videos. This man makes it so easy to understand the mechanics of the body that now I am wildly fascinated by it. This is what good teaching does.

    • @buffalobill2874
      @buffalobill2874 2 หลายเดือนก่อน

      Just try lots of sources. Some people converse better with each other so a lot of science and medical literature is suited to those on the same wave length but there are authors and presenters who can simplify content or word it a little differently to keep other people interested and engaged or just make it all click a little better.
      Every time I'm exposed to content I seem to get a better appreciation. Worryingly I do get decent marks when I don't feel confident in my understanding.

    • @goodyeoman4534
      @goodyeoman4534 2 หลายเดือนก่อน

      @@buffalobill2874 Good points. I like to reduce things to their basic concepts first and then repeat it over and over before I go onto the final details.
      I'm in cardiac science and KNOW most teachers overexplain almost everything. A lot of it is really not that difficult.

    Hi Dr Mike,
    I can't thank you enough for your generosity and dedication as your big help in every time I sending questions in comment
    Thank you so much for taking just 14 minutes to answer all of my questions about the cardiovascular system in great detail. When compared to two weeks of confusing lectures in class, this 14-minute video is worth every single second of your time. In terms of bridging the gaps in my knowledge, this video is the best one. In addition, you clarified plenty of confusing textbook terms for me.
    Just realised you made a lot of interesting TikTok clips, so I'll spend the rest of my exam prep time watching both your TikTok clips and your lectures on TH-cam again.
    I wish all the best come to you and your family.
    I'm going to spread the word about your TH-cam channel to all of my classmates because you're the best teacher ever.
    Because you're a lifesaver for patients and students alike, please keep up the great work.
    ❤❤❤❤❤👍👍👍👍👍👍👍👍👍👍👍👍

    You guys are seriously incredible and explain everything so well. Thank you so incredibly much. You are unbelievably underrated… definitely deserve more subscribers!!! I just don’t understand at all!
    Seriously thank you for everything you upload! One day notes or a website etc would be incredible if you ever have time ( me dreaming! I can dream!! I really already so grateful 😊). Silly coming from me, as I’ve actually finished my studies long ago but love to watch and refresh everything in a simple(?)/ straight forward & enjoyable manner. You are a favourite ‘tv show’ of mine!
    Wonder how it would have been if I had TH-cam back when I studied. I’m 36 & was a high definition student as I studied non stop and hard… videos like your would have made things even easier . Current students really should be incredibly grateful to you and I hope you are shown the appreciation you truly deserve!

    I think so many medical students, like myself, struggle with comprehending Afterload simply because of its name. Its name has very little correlation to its definition and can be misleading given the concept of preload fits its name in a general sense. Thank you for this video! Made it a lot clearer.
