"Types of Tissue Part 1: Epithelial Tissue When learning about the structure of the human body it's best to begin by learning about the types of tissues that are found within since all of the organs are made of different combinations of these types of tissues. First up is epithelial tissue since this makes up the outermost part of the skin. Let's learn all about various epithelia Watch the whole Anatomy & Physiology playlist: http://bit.ly/ProfDaveAnatPhys General Chemistry Tutorials: http://bit.ly/ProfDaveGenChem Organic Chemistry Tutorials: http://bit.ly/ProfDaveOrgChem Biochemistry"

"The Integumentary System I know we've only covered two out of the four types of tissue but that will be enough to start looking at some of the systems of the human body. We will start with the one that is easiest to see the integumentary system. This is made up of the skin and hair and nails as well as certain glands. It's actually quite a remarkable system so let's learn all about this now.

"Professor Dave Ruins Flat Earther Austin Witsit Remember when idiot flat earthers harassed me incessantly about debating David Weiss And then I agreed to debate him and completely humiliated him to the point where flat earthers started calling him controlled opposition Well they passed the torch to Austin Witsit and began pretending that I was too afraid to debate him too. So I agreed to do it and that's this. As expected it's nothing but word salads and pseudoscience from another flat earth grifter who is completely incapable of answering the same questions I ask of all flat earthers. Enjoy"
