 So the nucleus is sending information to build proteins. The rough ER is processing the proteins like bending them and folding them and making them so that they're functional. And my next structure, the Golgi bodies or the Golgi apparatus is responsible for packaging those proteins up so they can be barfed out into the world of the entire body to benefit from. The Golgi bodies look like a flattened stack of pancakes. Here they are. And they really look just like endoplasmic reticulum. And it is. Because remember, what is all this stuff made out of? It's all made of cell membrane. Notice that the structures that are being packaged, are sent from the endoplasmic reticulums to the Golgi body. So here's what happens. It's cell membrane. It pinches off and forms a little bubble. And the bubble then fuses with the Golgi bodies. And if you can imagine, here's a bubble of cell membrane that fuses with the Golgi bodies. And now whatever was inside of it is inside the Golgi bodies, which the Golgi bodies really are another maze of cell membrane. Once the substance is inside the Golgi bodies, then the Golgi body does more packaging and processing and organizing and folding and stuff happens to the stuff that went in there. And then the Golgi body says, okay, we feel pretty good about this. And then it pinches off a part of the cell, like a part of the maze that contains. It just pinches it off. And now you have a little vesicle. And that's where we're headed next. What are these vesicles going to do? Shall we go find out? I know you can't wait.
