Question

reasons for the following:
1. The urine present in the bladder does not flow back into the ureters​

Answer 1

While urine is in the bladder, it doesn't usually flow back into the ureters. When we pee, urine leaves the body through the urethra (yoo-REE-thruh), a tube at the bottom of the bladder. In vesicoureteral (ves-ih-koe-yoo-REE-ter-ul) reflux, pee backs up from the bladder into the ureters and sometimes to the kidneys.
