The bladder is made of stretchy muscle called smooth muscle. โจ
It has three layers: the inner lining, the muscle layer, and the outer layer. The shape of the bladder can change. When it's empty, it looks like a deflated balloon. When it's full, it's round and smooth! ๐
The bladder has a specific spot called the "trigone" that helps it function well. It connects to two tubes called
ureters, which bring pee from the kidneys, and one tube, the urethra, which lets pee exit the body. ๐
