Assume that the kidney stone in question has reached the bladder. what is the pathway of exit for this stone (i. e. what anatomic structures must the stone still pass through)? based on the anatomy of those structures, do you predict this to be difficult or easy? defend your answer.

Here's what I get  

Explanation:

From your bladder, the pathway of exit to the outside is through the urethra.

The diameter of the female urethra is about 6 mm. The male urethra is usually a bit larger.

Kidney stones can vary in size from 0.1 mm to over 40 mm in size.

Stones less than about 6 mm in size can usually pass through the urethra on their own with little or no pain.

Larger stones can be excruciatingly painful. The urethra cannot expand enough for them to pass through. Such stones usually need medical treatment to be removed.  

do yall know the answer?
