Next is connective tissue supports. So how does it support? Oh. You mean like mechanically support? It's wild card up to you now. Maybe it just kind of puts together the other three tissues that you spoke of. That one also sort of feeds into the next one I'm going to say. But you're right. Supply ways and you're wrong. Another way is bones again. They support the weight of our body. Cartlage supports the joints. The support is also like your kidneys. Otherwise they need to be supported. And obviously this isn't what we're going through is an exhaustive list. There's many ways, but these are examples.
