Average epithelial cell size is between 10 to 30 micrometers in diameter. When you think of your gut, it just is like a 7-meter tube. To have those additional projections, microvilli, would just improve or increase the surface area for that absorption. And other features? Then you could have things like enzymes.
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.
