RegisteredNurseRN this video is so easily to understand 😍😍😍thankkkk youuu

[@tamibhannaslack3941]

You are a very easy to understand teacher. This is really great for beginning A & P too! Wonderful refresher for what I have previously been taught. Excited to move forward as a Nursing Student (first year) and to watch more understandable teaching videos from RegisteredNurseRN!! You are the best!

[@quranavirus604]

[@blushdcoboudoir2484]

I'm in Dental hygiene and I cant express the gratitude I have for you. I suffer from a learning disability and ADHD and this helps. ALOT. I'm very thankful!

[@josiahischarismatic]

The best teacher I’ve ever had for understanding A&P, and clinical aspects. Hopefully this gets me one more step closer to my RN. Thank you Nurse Sarah!!!! ❤❤❤❤❤❤❤❤

[@tarabhandari7556]

I’m still in nursing school ALL because of YOU!! ❤️ English is my second language and I’m the only one in my family to actually go to college so it’s hard when you don’t have any study help. Plus, I hate to read textbooks for hours just to get even more confused and frustrated cause it’s so hard to visualize and grasp the concept. May God bless your soul. I’m in my last semester of nursing now and have been watching your videos all throughout my nursing journey. I truly feel that you’re an amazing gift from HEAVEN and feel like I owe you everything. Just saying THANK YoU from the bottom of my heart is NOT enough but I want to say THANK YOU anyway. Wish I could invite you to my graduation ceremony. You’re the BEST of the BEST. Keep SHINING ❤️ ❤️ ❤️ ❤️

[@kristenlawrence4177]

That was incredibly helpful!! I love how you broke it down with the visuals and then tied it together. It made so much sense, and I actual understand how it works now!

[@codyb701]

You are an awesome teacher! My roomie and I, both in nursing school, are always like "Sarah taught me that", or "Sarah explained that in her one video". Thanks for making some of the hard stuff easy to understand. I cannot imagine the amount of people you have taught through the years with your ability. Thank you. You are appreciated!!!

[@RegisteredNurseRN]

Wow, that is so very awesome! THANK YOU all for watching my videos! I'm honored to help you through nursing school. It is tough, but totally worth it! I wish you the best in your journey and thank you for using my videos to help you study. Please, tell your roomie I said "hello" and "thank you"!!

[@ericamariemoreno2478]

I am doing MLT . And it's my first semester. I was not understanding the concept of conducting system of heart . But now by watching your video I understood. Thank you soo much.

[@chivemince]

Very clearly explained and refreshing to see the teacher in front of you, rather than just behind the camera talking through the microphone. I find it helps me learn when I can see the person speaking for some reason!

[@RegisteredNurseRN]

+chivemince Thank you so much :) Yes, I totally agree with you. I learn better this way as well. Thank you for taking the time to leave a comment....I appreciate it very much!

OMG!! You have saved me. I started taking A&P II this semester. First test is this Friday, and I couldn’t put 2 and 2 together with the information provided by my professor. I even consider dropping out. It wasn’t me. It was the way the information was explained. Now, I understand everything about the electrical conduction system of the heart. The way blood flows in through the heart. Thank you, thank you Sara!!! 🙏🏻

Hi Sarah. As a fresh nursing student I've had a bit of difficulty in Anatomy and physiology, especially The systems related topics; Heart- circulation and conduction in particular.Your method of teaching g made it easy for me during revision in class. I'm so grateful and already shared with my seniors your website for references. Please could you guys make a helpful video post on, muscular, endocrine and immune systems?. I bet with your help acing class test and national exam won't be a problem. So grateful.
