The Cardiovascular System: An Overview
Вставка
- Опубліковано 28 тра 2024
- An introduction and broad overview of the cardiovascular system, including anatomy of the heart and blood vessels, the cardiac cycle, and cardiac histology. This is starting at the basics to bring all viewers up to the same starting point before doing deep dives on future topics.

Hello everyone! This is the first video of a planned 14-15 video series on cardiovascular physiology (Playlist: ua-cam.com/play/PLYojB5NEEakWY3ZS0acDMw4nbEZV-y7pk.html ). Each video is 15-30 minutes in length. It's starting at the basics so that viewers with different backgrounds (e.g. high school vs. undergrad, premed vs. non premed, etc...) can have the same background knowledge before deep dives on subsequent topics.
The tentative list of video topics:
Overview of the CV system (i.e. this video)
The Cardiac Action Potential
Excitation-Contraction Coupling
Cardiac Mechanics (preload, afterload, contractility, ejection fraction)
The Cardiac Cycle and PV Loops (including cardiac work)
Hemodynamics
Viscosity and Turbulence
Arterial Blood Pressure
Nervous System Regulation of the Cardiovascular System
Hormonal Regulation of the Cardiovascular System
Integration of CV Regulation (i.e. complete description of what your CV system does during exercise, dehydration, septic shock, weightlessness, etc...)
Vascular Biology
Coronary Circulation
The Microcirculation and Lymphatics
Cardiac Embryology
If this is successful, the following stage would be to intersperse path and pharm topics into the playlist (e.g. pathophysiology of heart failure following cardiac mechanics, atherosclerosis following vascular biology, etc...), with the eventual goal of replicating the content of a medical school CV organ block.
Let me know what you think!
I am loving the series, thank you a lot.
Thank you Dr. Strong - outstanding and appreciated.
sir I watched your 8 videos on playlist, but when will you upload the rest of them.
Need lecture about principle of TEE and PCI thank you
I appreciate the pace, depth and overall delivery of your work and have subscribed - please don’t change a thing and keep them coming thank you ❤
I teach anatomy and physiology to high school students. Much of what Dr. Strong covers in his videos is beyond the scope of my course. However, his videos represent the epitome of what educational UA-cam videos should look like. There is no "flash" or "bang" to distract the viewer, just high-quality graphics accompanied by his clear and concise instruction. He is clearly a person who is committed to education. Thank you, Dr. Strong for your efforts, and keep up the good work.
Thank you so much for the kind words! You've probably already discovered this, but Crash Course Anatomy & Physiology is pretty good and seems close to high school level. Also, the channel Corporis doesn't have a complete A&P playlist, but has some great stand alone videos at the high school and college level, including some interesting ones on the history of medicine.
@@StrongMed I am indeed familiar with both of those channels. While Crash Course is excellent, I have a couple of problems with it. The speed of narration can be overwhelming for some students. They really try to pack a lot of information into a 10-15 minute video. Additionally, some of the animations are superfluous and distracting at times. I feel that many of my students would appreciate the very clear, systematic approach that you use. Some of your videos I could certainly use for my class, most go above and beyond what my students are ready for. I really enjoyed your introductory video on hemostasis. It provides a better foundation for the topic than anything I have read in the A & P textbooks. I could use this video, the subsequent videos are more than likely too much for my students. I plan to watch the whole series this summer. I find the topic very complex, frustrating, yet interesting. Keep doing what you do. I haven't visited Patreon yet, but I plan on doing so. Thank you!
if this dude gave my lectures in med school i might have actually entered residency with some practical knowledge..
yes
Always that teacher is the problem... perhaps if you had been a different kind of student
@@bellehealingmusic434 I aced all my tests and got 99th percentile on boards. I was an excellent student. My teachers still sucked and i had to learn everything on my own lol
I'm not a leg man, compliments from me are as rare as water in the Gobie Desert, IN SHORT,.....this youtube chanel is one of the most profound medical contributions for learning I've come across,...for studying, this is my 2021 highlight, to say Way Cool.....is an understatement.

Thank you so much , definitely helping in my recertification exams as I have forgotten the basics in the past 20 years while pursuing another specialty, feel like an excited med school student while watching these videos , you definitely are one of the best teachers I have come across
What an outstanding lecture! I salute your parents and teachers for producing such an knowledgeable person.
This is literal gold! Thank you so much; I'm really enjoying your cardiovascular content!
This is a fantastic lecture of this topic. I found myself revisit this lecture again and may be again. This lecture is unrivaled. I thank you Dr Strong very much.
Seriously, I should have had YOU as a teacher in medical school. This video really drops. Exceptionally well done.
Dr. Strong!! Very precise and clear presentation!!! Ty so much for your time making this incredible lecture possible. 😊
Thank you so much. I have a test tomorrow and this video completely saved my life.
I'm taking an EKG class and I have to remember all the names, locations,functions and this has diffently helped me understand it more. Thank you.
wow this helped me out massively!! i found it hard to understand my teacher when she was explaining the cardiovascular system and never had a clue what she was on about, until i found this video 2 weeks before my a level exam, which is on the 25th of may 2023! thank you so much for making videos like these, will be returning for more :)))
thank you i see many lectures but litterly no one can be explain like , you explain very well and everything keep in mind
its good to being with your lecture. you are fully capable to apperciate
Studying for the HESI, wish me luck!!! Thank you for the best information given in the shortest amount of time!
Thank you very much Dr Eric Strong, especially to review this , I am looking forward to watch this series of you. I pretty know EKG from your EKG series , you are great teacher/instructor indeed.
Amazing explanations, particularly the cardiac cycle
Much appreciation for all your videos, many thanks.
Thank you so much for this excellent overview, Dr. Strong!!
Glad it was helpful!
Simple and thorough knowledge Sir. Thank you so much. ❤
Fantastic lecture! I’m an old nurse but new health science teacher so this was a great refresher for me!
Wonderful video.. very clear concepts. Thanks a lot Dr. Eric
you are the best Dr Strong,thank you very much
I'm new here and trying to learn more about the cardiovascular system. Thanks for your tutorials
I highly appreciate this series Eric!! Keep up the good work!
Thank you for the great overview! Looking forward to your more in-depth videos on the cardiovascular system.
Thank you so much Dr. Eric 🙏
Thanks so much for this video! Definitely answered a lot of my questions.
AMAZING. Thanks, doc!

Awesome!!
Thank You!
Well explained
Thank you
Thank you!
Hello sir can you please make a video on foetal circulation? Love this video btw
Thank you ❤
hey i am from India the video is nice
Ooooh you have new visuals for titles
You are my hero
Very nice
outstanding
fun knowledge !!
THANKS!
Saw the thumbnail and thought it was Chris Parnell 😂
I usually get that or Alan Ruck.
I don't get why anyone would click dislike on this video
Thank you dr eric for your lectures, I hope to include POCUS of the heart and later on U/S of the lungs to your lecture series.
Or can you make a series of lectures about basics of ultrasound and then its application
"POCUS".
Thanks for the suggestion! I 100% agree that POCUS is an important and undervalued part of medical training. It's on my master list of topics to cover here on the channel, but truthfully, it feels like for every topic I finish and post, 2 more ideas get added!
there are several on UA-cam already but I dont disagree that at some point in the future he will probably do them

Nice
The oxygenated or deoxygenated blood ???
Ce lecon des ans passeee malgre cela il est encore tirer bien au sens de ameliorer de nos besoins de vivante sur cette planete!
THANKS i can pass biology now!!

Are you gonna make a video on your opinions of the AstraZeneca vaccine? I think it would be really interesting.
My opinion of the AstraZeneca/Oxford vaccine: I'm glad I was able to get Pfizer's...
Seriously though, maybe once/if it's authorized in the US, I'll tackle it. But its whole story is a bit of a cluster. I don't understand how a major company could make such unforced errors with something this big.
Please, send me the autonomous nervous system too. Thank you.
Remember the paradox of deoxygenated venous blood from the lung tissue returning to the left atrium….Bronchial Venous return …which in cardiac surgery for mitral valve replacement can flood the field for a cardiac surgeon …the ONE anomaly of deoxygenated blood returning to an oxygenated blood chamber …perfusionists know this well
GOAT
I want the video for type of tissues
Here's an introductory video on histology from Corporis I recommend: ua-cam.com/video/S59JwFCjNhc/v-deo.html
And if you want something with more detail, here is one from The Noted Anatomist: ua-cam.com/video/0U5J_unEM-Q/v-deo.html
None of my professors described the cardiovascular system this good when I was in medical school. By Amelia
Bit fast but very very helpful
Please if there is evaluation test share it
Not sure what you mean. An assessment to see if you understand the material presented in the video? If so, I'm sorry but I don't have one.
@@StrongMed yeah its all about that assessment. BUT thank you for your studies.
👏👏
I want enter this coarse teacher as master cardiologist
👏🏻👏🏻👏🏻👏🏻
Kindly explain with captions
Closed captions are available for this video. Can you specify if you are suggesting something more?
i m high school drop out but is interested in how human body works.
God damnit man.. ... Where have you been all my life?? Better late than never ..eh ❤️❤️❤️❤️❤️❤️❤️❤️❤️❤️❤️❤️❤️❤️❤️❤️❤️❤️❤️❤️❤️❤️❤️❤️
