This episode covers the Cardiac Cycle, which is everything that happens in the heart from the beginning of one heartbeat to the beginning of the next heartbeat. The best visual for this is the Wiggers Diagram, which I have posted on instagram (studenthelp4AP) and twitter (@studenthelp4AP). I recommend using this image to following along.

I also answer a question about hydration from listener Ali. Please follow me on my socials and feel free to use them to ask me a question. You can also email me at [email protected].

Episode 47 covers the electrical activity of the heart as well as explains the ECG. The heart is unique that it generates and conducts its own electrical signals without a need for motor neurons. For an in-depth look at the human heart and the rest of the human body, check out A&P Digital Suite for over 150 A&P tutor videos I've made, study guides, and comprehensive anatomy and physiology lab simulations. Feel free to email me at [email protected] and ask me questions. I just may answer them on the show.

This episode covers the histology of cardiac muscle tissue including how some cardiac muscles cells generate their own electrical signals. This is how the heart beats without being innervated by neurons. I also talk about coronary artery disease and bypass surgery. Remember to email me at [email protected] if you have questions and visit my youtube channel. Tell your professors about A&P Digital Suite where they can assign 155 of my tutor videos as well as industry-leading A&P lab simulations.
