The ureters are made up of three main layers. The outer layer is called the adventitia, which provides protection. The middle layer is smooth muscle, which helps push urine down to the
bladder through a process called peristalsis. ๐
The inner layer, called the mucosa, helps keep the inside of the ureter moist. Have you ever seen a long straw? ๐น
The ureters are kind of like straws for urine! One end connects to the kidney, where urine is created, and the other end connects to the bladder, ready for storage!
