Final answer:
Lymph nodes are not located around the heart; they are typically found in the axillary, cervical, inguinal regions, and around the intestines.
Step-by-step explanation:
The location where lymph nodes are not found is around the heart. Lymph nodes are small, bean-shaped structures that are part of the lymphatic system. They are key sites where immune responses are generated. Lymph nodes are distributed at various locations in the body such as the axillary (arm pit) region, cervical (neck) region, inguinal (groin) region, and around the intestines. However, there are no clusters of lymph nodes directly around the heart. The lymphatic system does include lymphatic vessels that extend in the vicinity of the heart, but not lymph nodes as found in the aforementioned areas.
