We mention specialized cells can develop a mucus layer - and that they divide frequently - which can be protective for the stomach lining. However, there's more! Did you know many enzymes (like pepsin) are secreted in an inactive form and don't activate until reaching a different location? Learn more below!

And when the world needed them the most, they returned.

Still helping me in college level anatomy/physiology. Thank you Amoeba Sisters!

You have to add subtitles in spanish, I live in Mexico and students will go crazy for your adorable videos. They really help me understanding some concepts. Keep on the good work. Thanks.

I managed to make it into college without taking a Biology class, which was probably a mistake. Now I have to take a Biology class when my last experience with Biology was in 7th grade. Luckily, your videos make it a lot easier to take in the material. Thank you! You're a life saver.

Thank you Amoeba Sisters. I am currently working on a digestive system project in which I have to make a piece of food travel through he digestive tract. Watching this video really helped me understand which directions to take. I love how you included even the tiniest details like the epiglottis and the chyme. I appreciate you a lot. Thanks again!!!
