I coughed this up and now I’m scared

i don’t know what this is but it looks like it has blood vessels in it. it looks ripped off from something else.

i had ramen last night but the noodles weren’t flat, and it doesn’t look like the noodles i was eating or anything else i ate.

please help, im not having any pain, just a sore throat so i was coughing hard to try to get mucus out.

i can’t figure out what this is, and i threw it out because it started drying out really quickly. im worried this is a piece of my body.

its 2 layers on the long part, the top is like a tube that got broken. one side is flat, the other side is textured (leathery?)

if this isn’t the right sub please point me in the right direction. not having pain or anything, just scared of what this is. the last pic i ripped the 2 layers apart
