Vocabulary flashcards defining the major human organ systems and their primary physiological functions based on the lecture notes.

Nervous System

Detects, integrates, and responds to stimuli from outside and within the body; works with the endocrine system to coordinate all organ functions.

Endocrine System

Produces hormones and works with the nervous system to control many body functions, including reproduction, response to stress, and metabolism.
