Noun and の adjective
ないぞう
ご近所さんのガレージで鹿の内臓を取り出すんです。
They take the internal organs out of deer in my neighbor’s garage.
Inside internal organs are your internal organs, though you'd think the second kanji would give a hint to that without the 内.
This is a jukugo word that uses the on'yomi readings of the kanji. You should be able to read this on your own.
