5 random things I just learned that may or may not be important

So I learned these random facts and honestly thought they didn't matter:

1. The left kidney sits higher than the right one
2. The entrance to the right lung is more vertical than the entrance to the left
3. The appendix is 3-5 inches long
4. The skin of the abdomen develops in horizontal lines
5. The left testicle hangs lower than the right one

And then I found out that sometimes seemingly random facts actually are important and even if they don't make sense at the time, it is worth knowing them. Here's why:

1. Because the left kidney is higher, the ureter (tube leading to bladder) is longer. In kidney transplants, the left kidney is always used because the longer ureter gives more length for stitching it in.
2. When small objects are inhaled, they tend to follow a vertical path and almost always end up in the right lung.
3. A 5-inch appendix that is very swollen from appendicitis can look like part of the small intestine on an X-ray or ultrasound
4. If the abdomen is cut vertically, it will leave a fatter scar than if cut horizontally, along the natural lines of cleavage.
5. I have no idea why this last tidbit is important, but I'm willing to believe that it might be. And that someone somewhere cares.
