Communication

Transport systems enable the cells of the body to have access to external and internal environments. The blood, circulatory system and lymphatic system transport various substances to and from different parts of the body. All communication systems of the body receive and collate information and provide appropriate responses.

There are different systems for communicating with internal and external environments. The nervous and endocrine systems manage internal communication. These systems regulate the vital functions of the body and maintain homeostasis. The special senses and verbal and nonverbal activities are involved in communication with the external environment. All of these also depend on the nervous system.
