Question

Quizplus · Accepted Answer

The nervous system and endocrine system are the two body-wide communication systems. The nervous system uses electrical impulses to communicate quickly with specific target cells, while the endocrine system uses hormones to communicate more slowly and widely throughout the body. The other choices, blood and lymphatic system, are important for transportation within the body but are not considered communication systems. The cardiovascular system is composed of both blood and the lymphatic system, which are important for transportation, but the system as a whole is not considered a communication system.
