Question

The ureters enter the bladder at what angle? Why is this angle important? This angle entering in forms what valve?

A) 90 degrees, preventing backflow, urethral sphincter
B) 45 degrees, facilitating urine flow, tricuspid valve
C) 60 degrees, preventing reflux, urethral crest
D) 120 degrees, promoting mixing, pelvic valve

Answer 1

The ureters enter the bladder obliquely, at an angle rather than 90 degrees. This angle is important because it creates a one-way valve that prevents reflux of urine from the bladder back into the ureter, preventing the risk of urinary tract infections.

Step-by-step explanation:

The ureters enter the bladder obliquely, at an angle rather than 90 degrees. This angle is important because it creates a one-way valve that allows urine to enter the bladder but prevents reflux of urine from the bladder back into the ureter, preventing the risk of urinary tract infections. It is called the ureterovesical junction.
