Liver
Chutzpah, Courage
noun
The kanji and the word are exactly the same. That means they share meanings as well. Though, it also means chutzpah or courage (besides just being liver). Maybe your liver is where your courage is.
きも
Since this word is made up of a single kanji, it probably uses the kun'yomi reading. You did not learn this reading, so here's a mnemonic to help you to remember: Your liver isn't doing great. You have cancer in your liver, so now they're giving you chemo (きも) to help get rid of that cancer.
トイレに行く前に、鳥の肝をもう一口かじりました。
I took another bite of chicken liver before going to the bathroom.
