Blood
noun
The kanji and the word are exactly the same. That means they share meanings as well.
ち
Since this word is made up of a single kanji, it should use the kun'yomi reading. When learning the kanji, you didn't learn that reading, so here's a mnemonic to help you with this word: You cut yourself and there's blood everywhere. You need to stop the bleeding with something, but the only thing nearby is a block of cheese. You grab the cheese and stuff it into your gash, but the blood comes out the holes (it is Swiss cheese, blargh!). Imagine this in great detail to be able to remember it well.
シャツに血がついていますよ。
There is blood on your shirt.
うわ、足首から血が出てる！
Yikes, blood is coming out of my ankle!
父は、私と血がつながってません。
My father is not related to me by blood.
