Directing immediate responses to stimuli, usually by coordinating the activities of other organ systems is the function of the ________.

A) integumentary system
B) endocrine system
C) urinary system
D) nervous system
E) reproductive system

Answer 1

The function of directing immediate responses to stimuli by coordinating the activities of other organ systems is performed by the nervous system, especially evident during the fight-or-flight response.

Step-by-step explanation:

Directing immediate responses to stimuli, usually by coordinating the activities of other organ systems, is the function of the nervous system. The nervous system acquires information from sensory organs, processes it, and then initiates a response through motor function or changes in the organism's physiological state.

For example, during the fight-or-flight response, it is the fast action of the nervous system in response to danger that stimulates the adrenal glands to secrete hormones, leading to rapid responses throughout the body, including increased heart rate and diversion of blood away from the digestive system.
