Anatomy of the Heart
The heart is a muscular organ about the size of a fist. It pumps blood throughout the body, commanding a vast vascular network to deliver oxygen to every cell in the body. It beats nonstop for as long as we are alive, at an average of 80/min. So by the time we are 80 years old, our hearts will have beaten more than 3 billion times! The heart’s position in the center of our chest mimics the organ’s central position as the source of human love, spirituality, courage, and resistance. It is an amazingly beautiful organ; let’s learn more about its anatomy. After listening to this AudioBrick, you should be able to: * Describe the pericardial sac and its layers, the pericardial space, and the pericardial fluid. * Identify the three layers of the heart. * Identify the four heart chambers, describe their topography, and explain their functions during systole and diastole. * Describe the systemic and pulmonary vessels that enter and exit the heart, including their origin and destination, and the oxygenation status of the blood being transported. * Explain the basic functional anatomy of the atrioventricular (AV) and semilunar valves, and explain how they operate during systole and diastole to create the four heart sounds (S1, S2, S3, and S4). * Describe the role of papillary muscles and chordae tendineae. You can also check out the original Anatomy of the Heart brick from our Cardiovascular collection, which is available for free.

Podcast 618: Treating Opiate Side Effects
Contributor: Don Stader, MD Educational Pearls: * Majority of patients experience side effects while taking opioids * Most common include nausea/vomiting, puriitis, constipation; more severe and less common include respiratory depression, addiction and overdose * Opiates can cause nausea, but ondansetron (Zofran) is the wrong treatment because it’s not antidopaminergic. Instead consider using metoclopramide (Reglan), olanzapine (Zyprexa), or haloperidol (Haldol) * Itching from opiates isn’t histamine mediated so hydroxyzine (Atarax) and diphenhydramine (Benadryl) aren’t effective - oddly ondansetron may help with itching. * Constipation is best treated with promotility agents like Senna, rather than stool softeners References Rogers E, Mehta S, Shengelia R, Reid MC.

Ep. 49 - Why diets fail, Willpower vs. Mindset and how to shift your thinking | Intermittent Fasting for Maintenance | Long-term Intermittent Fasting | Free OMAD Intermittent Fasting Plan
ANNOUNCEMENT! THANKS TO LISTENER FEEDBACK, WE'RE DOING ONE MORE CHALLENGE THIS YEAR 12/3 - 12/12! REGISTER HERE! In this episode, Dr. Scott and Tommy dive deep into the struggle many people face when it comes to transitioning from a "diet" and into maintaining their healthy goal weight. The disconnect between how one reached their goal and the optimal techniques to maintain it can cause confusion, frustration, and oftentimes complete regression back to an unhealthy body composition. Willpower is a key component in this equation, and the mindset shift away from dieting and toward lifestyle design allows for freedom and proactive decisions that have staying power.
