Explanation:
Kim Roberts explains the importance of the T cells in our immune system in his poem, "Immunity".
He describes the T cells as holding sheets. Also, he describes them as protectors which protects the immune system.
He compares T cells to "sentries " that stand "at a crenellated wall." He further reveals that he could hear their "rhythmic chant."
The author emphasizes that, without T cells, it would be impossible to build a strong immune system.
The T cells, also known as T lymphocyte, type of leukocyte (white blood cell) are essential part of human's immune system.
