Question

how does stress affect your nervous system?
a. signals endocrine system to produce hormones to elevate heart and breathing rate
b. signals the respiratory system to reduce the breathing rate
c. signals musculoskeletal system to cause rapid and uncontrollable movements
d. signals digestive system to stop digesting food

Explanation:

When stressed, the nervous system activates the body's "fight - or - flight" response. This involves signaling the endocrine system to release hormones like adrenaline, which elevates heart and breathing rates. The other options are incorrect as stress generally increases breathing rate, not decreases it (B), doesn't typically cause rapid and uncontrollable movements in the musculoskeletal system as a primary response (C), and while stress can affect digestion, it's not the main way the nervous system responds to stress compared to the endocrine - related response (D).

Answer:

A. signals endocrine system to produce hormones to elevate heart and breathing rate
