Yes there are two one to prevent reflux at the the bottom where it connects to the stomach and one at the top which stops are feom going to the stomach and food from going into your lungs (Sauce ) .

According to the Wikipedia article there are 50 types/kinds but I haven't found how many we can control. One of the most important though is the urethral sphincter which controls urine exiting the body (or sperm in people that produce it).

I'm semi-ashamed to admit this is something I would have upvoted a while back ago

[–] KombatWombat@lemmy.world 9 points 6 days ago (1 children)

I still upvote it, but now it's ironically.

I upvote it, knowing it is ironic, but with the added layer that it is partly relatable. But that liking it completely unironically is dumb.

(How many irony levels can we get to this way?)

Growth is nothing of which to be ashamed. Had you still been that person, is where the true shame would lie.
