Document Summary

Without the urinary part of the genitourinary system we are dead ducks. Without the genital part of the genitourinary system we cease to exist as a species. nothing: the reproductive and renal system have essentially in common physiologically but everything in common developmentally and anatomically. Kinky path: uteropelvic junction, cross over the psoas muscle and the iliac and veins, kinked, ureterovesicular junction: where the ureter goes bladder, has a kink as well, narrow. Kidney stones often get held up at the arteries into the uretropelvic or ureterovesicular junction or in the crossing. The ureters are muscular tubes: the muscle layers will produce waves of peristalsis to push urine to the bladder, muscularis layers: smooth muscle. *opposite from gi: epithelial layer: inner mucosa or mucous membrane (that is that it has mucus-producing cells) and it is transitional epithelium that can expand greatly with increased volume. Mucus gets pushed down with urine layer. Ilium: sciatic notch: sciatic nerve comes out here.
