Question

Quizplus · Accepted Answer

Lymph nodes are responsible for filtering and purifying lymph before it returns to the bloodstream through the veins. They contain specialized immune cells that can detect and respond to pathogens, abnormal cells, or other foreign substances that may be present in lymph. However, lymph nodes do not contain the largest collection of lymphoid tissue in the body, nor are they the site of T cell maturation, or stimulate lymphocyte stem-cell division. They also do not remove abnormal blood cells and components, as that is primarily the function of the spleen.
