ChatGPT is changing lives and there has been a lot of focus on how students are using it and teachers are combating it, but there has not been any focus on how teachers can leverage AI to make their jobs and lives earlier and less stressful. Former Biology Professor turned tech and social media expert, Leslie Samuel wants to share how teachers can leverage AI instead of fighting against it.

Here's a nice and easy song to help you remember the journey of food down the Digestive System. Sing along, enjoy, and learn! Written by: Leslie Samuel, IG: @iamlesliesamuel https://www.interactive-biology.com Produced by: Jeffrey Monestime, IG: @jmonestimemusic - https://www.jmonestimemusic.com Lyrics: The digestive system is how we eat The fruits and the veggies or rice and meat This is a journey that starts in your mouth The digestive system is what it’s all about From the mouth to esophagus the stomach, that’s fine And then to the small and large intestines The rectum and the anus and then it comes out The digestive system is what it’s all about

Artificial Intelligence, ChatGPT, and all these different platforms - are they coming for our jobs? Should biology teachers be afraid? In this video, I share some ways ChatGPT can help biology teachers be better at their jobs.

FREE Cardiac Cycle Guide - https://www.interactive-biology.com/cardiaccycle3 The Cardiac cycle is one that a lot of people struggle with. In this video, I break down the last three phases of the cycle so that you can understand it. First two parts: Cardiac Cycle 1 - https://youtu.be/LzWQkxqwans Cardiac Cycle 2 - https://youtu.be/EWeHW14H2lg Topics Covered: 00:00 Intro 01:13 Pressure Buildup 01:46 Ejection Phase 03:23 Rapid vs Slow Ejection 04:03 Cardiac Cycle Guide 04:15 Blood Pressure 05:39 Blood Volume 06:29 EKG and T Wave 07:05 Isovolumetric Relaxation 08:40 Dicrotic Notch 09:36 Heart Sound 09:59 Ventricular Filling 10:57 Cardiac Cycle Recap

The cardiac cycle looks at all of the things that happen from the beginning of one heartbeat to the beginning of another. Phase 2 of the cardiac cycle is called Isovolumetric Ventricular Contraction. We cover the QRS complex of the EKG, the roles of the atrioventricular and aortic semilunar valves, the pressure and volume changes in the atria and ventricles, and how these all factor into the building up of the pressure needed to send the blood throughout the body.

The first phase of the Cardiac Cycle is Atrial Systole. In this phase, we see a number of things happening. We take a look at the P wave of the electrocardiogram, the pressure changes in the atria and ventricles, as well as the volume of blood in the ventricles.

How do muscles actually contract? There's a lot involved in the process. And in this video, we talk about muscle contraction at the molecular level. We'll discuss sarcomeres, actin, myosin, the muscle action potential and the roles of ATP and calcium ion. Press play and enjoy.
