Question

Quizplus · Accepted Answer

The immune system and the lymphatic system are closely associated because lymphocytes (a type of white blood cell important in immune responses) are produced and stored in the lymphatic organs, including the lymph nodes and spleen.

Note: None of the other statements are correct. Organ systems are made up of organs, which in turn are made up of tissues composed of cells. Organ systems work together to maintain homeostasis, which depends on communication and coordination between systems. The endocrine system is a true structural system composed of glands that produce hormones.
