I know I promised to respond to Hubey anymore, but sometimes he begs for
it. I'm weak.

Tears proportionally contain the same amount of saline as the rest of the
body. When a tear is excreted, the body has lost that much mass, a small
proportion of which is salt. Since the proportion of salt in the tear is
the same as the proportion of salt in the body, the proportion of salt in
the body doesn't change. You may call something that doesn't change the
salt proportion of the body a "salt-excretion mechanism" if you wish. It
doesn't change the fact that tears are not an effective mechanism for
ridding the body of excess salt.
