Final answer:
The ureters and the urethra connect to the bladder on its inferior and posterior surface, which is important for preventing UTIs and ensuring efficient urination.
Step-by-step explanation:
The ureters and the urethra join the urinary bladder on the inferior and posterior surface. This anatomical configuration is essential for the proper function of the urinary system. The ureters connect to the bladder at an oblique angle, which helps create a physiological sphincter to prevent urine from flowing back into the ureters.
As for the urethra, it begins inferiorly and centrally, forming the base of the trigonal area at the bladder's base. This structure extends to transport urine out of the body, and its position reflects the consideration of urinary function and the prevention of urinary tract infections (UTIs).
