Episode notes

We don't call it simple squamous tissue of your atria or your ventricles. We call it endothelium. What's underlying the endothelium will be a very thin layer of connective tissue, but will be a thick layer of muscle tissue. So you're not just going to have muscle exposed to the blood inside your heart. It just doesn't happen, right? You're always going to have this cellophane or cling wrap or whatever that’s wrapping around it to protect it. Okay. The next term is a simple squamous that wraps the outside of the heart or the peritoneum or the pleura. And so then...

One of the four tissue types of the body, epithelia lines and protects our organs from the external and internal environment. In this episode, Dr Matt & Dr Mike explain how the different shape and layers of epithelia tell you what function it performs (form = functions) and highlight examples in the body where you can find each type. They also explore cancer, metaplasia, dysplasia, and Dr Matt's mums skin cancer diagnosis and surgery.
