Answer: By comparing T cells to soldiers, the author stresses their importance in keeping the immune system healthy.
Explanation:
In his poem,<em> "Immunity"</em>, Kim Roberts stresses the importance of T cells for our immune system.
He compares T cells to "sentries
" that stand "at a crenellated wall." In other words, these cells protect our immune system, just like the warriors protect their defensive wall in a battle. He describes the cells as holding sheets, and he can hear their "rhythmic chant." With this word choice, the author emphasizes that, without T cells, it would be impossible to preserve immunity.
