Listen to review 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.

Genetics and Heredity for A&P - Episode 79 Nov 18, 2025

Show notes

Episode 79 covers Genetics and Heredity for A&P. This is an accessible discussion of genetics for anyone interested in a general overview of genes and heredity. Almost every A&P text will cover some level of genetics, which is essential for understanding the basis of many diseases. I discuss chromosomes, dominance, co-dominance, incomplete dominance, epigenetics, and more. I also recommend one of my favorite podcasts, SmartyPants Wonders. A perfectly succinct show about animals that is targeted to kids, but enjoyable for all. I highly recommend taking a break and giving it a listen. It’s so much fun. You can get it on Apple, Spotify, or any podcast platform.
