Final answer:
The term for the removal of a lymph node is 'lymphadenectomy,' combining 'lymph-', '-aden-' for gland, and '-ectomy' for surgical removal.
Step-by-step explanation:
The combination of word parts needed to build a term that means the removal of a lymph node is lymphadenectomy. This term is composed of three parts: 'lymph-' referring to lymph or lymphatic system, '-aden-' meaning gland, which in this context refers to the lymph node, and '-ectomy' indicating the surgical removal of a part of the body. 'Lymphadenectomy' is thus the surgical procedure for the removal of one or more lymph nodes, often performed to check for the presence of cancerous cells in cases of suspected lymphoma.
