• Alzheimer Disease and Parkinson Disease - Episode 89 22.04.2026 36λ

  Episode 89 covers two of the most common neurological diseases of aging, Alzheimer and Parkinson disease. I know it sounds odd without the possessive, but that's the standard when it's written. These diseases are often reduced to "dementia" and "tremors," but there is so much more to their mechanisms, signs, symptoms, findings, treatments, and prognoses. We discuss the anatomical background needed to understand these diseases and their clinical significance.

It is the perfect clinical application of the respiratory system.
• Joints (Part 2) - Episode 86 19.03.2026 51λ

  This is ANOTHER bonus mid-week episode at the request of a listener! Mykenzie from Minnesota asked for an episode on joints, and that is what you’re all going to get. In fact, you’re getting TWO episodes on joints because it’s just too much information for one! Joints (Part 2) focuses on synovial joints. I discuss the angular movements that take place at joints and the most clinically significant synovial joints in the human body, including their structure, function, and the common injuries that harm them. Thanks again, Mykenzie, for reaching out!

  This is a bonus mid-week episode at the request of a listener! Mykenzie from Minnesota asked for an episode on joints, and that is what you’re all going to get. In fact, you’re getting TWO episodes on joints because it’s just too much information for one! Joints (Part 1) covers the basics of arthrology, basic anatomy, classes of joints, lever systems, and range of motion. Thanks, Mykenzie, for reaching out!
• What is Cancer? - Episode 83 (with Christy Kestner, PhD) 09.03.2026 47λ

  This episode asks the important and broad question, “What is Cancer?” To answer it, I spoke with Dr. Christy Kestner, PhD. Dr. Kestner has a PhD in Neuroscience, with a focus on immunology and oncology. We discuss the cellular basis of cancer, signs & symptoms, types, risk factors, causes, treatments, and more. Basically, the nuts and bolts of cancer. You can find Dr. Kestner on Instagram, Substack, TikTok, Medium, YouTube and LinkedIn.
• Diabetes Mellitus - Episode 82 02.03.2026 43λ

  This episode covers one of the most common diseases in the world, diabetes mellitus. Most people know someone with diabetes, whether it’s type 1 or type 2. We discuss exactly what diabetes mellitus is, the difference between type 1 & 2, the causes, risk factors, signs & symptoms, lab findings, exam findings, complications, treatments, prognoses, and more. It is the 7th leading cause of death in the US and 8th in the world, costing over $1 trillion per year in healthcare costs.
• Coronary Artery Disease - Episode 81 23.02.2026 43λ

  This episode covers the number 1 cause of death in the history of the human race, coronary artery disease, the most common form of heart disease. It’s also known as ischemic heart disease.

Among other things, we discuss its causes, risk factors, signs, symptoms, exam findings, lab findings, treatments, and prognoses. Just about everyone knows someone with coronary artery disease and just about all of us will have some degree of it if we’re lucky enough to live that long.
• REBOOT: The Cytoplasm of the Human Cell (Episode 5) 19.02.2026 50λ

  This is a REBOOT of episode 5. I have added more pertinent content that you are probably going to need in A&P. This reboot is an in-depth look at the cytoplasm of a human cell. We discuss organelles, inclusions, cytosol, the cytoskeleton, glycolysis, anaerobic fermentation, aerobic respiration, and a little bit about the nucleus.
• Big Announcement for 'A&P: Bit by Bit' Listeners 16.02.2026 2λ

  Anatomy & Physiology: Bit by Bit is shifting gears! Now that most of the content covered in a typical A&P course has been covered, it's time to move toward CLINICAL APPLICATION. Each episode will now focus on specific diseases, conditions, and injuries. Being able to apply the concepts in A&P to clinical scenarios is the best way to show mastery! The first clinical episode will drop on February 23rd and cover the most common cause of mortality in the world: Ischemic Heart Disease. Join me on this journey to understanding human health and disease.
• REBOOT: Specifics of Membrane Transport - Episode 4 12.02.2026 50λ

  This episode discusses the important topic of membrane transport, which is how water, solutes, ions, metabolic waste, and other materials enter and exit the cell across its plasma membrane. Diffusion and osmosis, passive and active transport, you name it. This is one of the most important concepts in cellular physiology.
• REBOOT: Cells and Their Plasma Membrane: Episode 3 14.01.2026 33λ

  This episode introduces the cell and discusses the plasma membrane in detail. This includes the phospholipid bilayer, cholesterol, and membrane proteins. Since it was first released in 2019, I have added some content and improved the audio quality. Check it out for a much-needed review!

Episode 2 now covers the 6 essential characteristics of living things and the principles of homeostasis. Homeostasis is the way our bodies maintain a consistent internal environment despite living in an inconsistent external environment. Negative and positive feedback systems are explained and discussed, with many clinical examples provided.

  This BONUS Episode is a reboot of Episode 1 from back in 2019. I have re-recorded some of it for better audio quality and added more content than existed in the originally aired episode. The basis for Human Anatomy & Physiology is how the body is organized and the anatomical terminology we use to discuss it. I recommend listening to this episode and then going all the way back to Episode 2 and advancing from there.
