A “flight or fight” response occurs when the body perceives a type of threat. The hormone known as adrenaline is released which will affect a variety of body systems. Which system needs to increase its activity in order for the muscular system to respond to the perceived threat?
A-Endocrine
B-Excretory
C-Digestive
D-Integumentary
The system that needs to increase its activity in order for the muscular system to respond to a perceived threat is the Endocrine system.
To arrive at this answer, we need to understand the concept of the "flight or fight" response and how it relates to the different body systems.
The "flight or fight" response is a physiological reaction that occurs when the body perceives a potential threat or danger. It prepares the body to either confront the threat or escape from it.
During this response, the endocrine system releases the hormone adrenaline (also known as epinephrine) into the bloodstream. Adrenaline affects various body systems, including the muscular system, to enable a quick and efficient response to the perceived threat.
The primary function of the endocrine system is to regulate and control the release of hormones, which act as chemical messengers. These hormones travel through the bloodstream and affect target organs or tissues, stimulating or inhibiting various physiological processes. In the case of adrenaline, it binds to specific receptors in the muscles, leading to an increase in muscular activity. This heightened muscular activity allows the individual to either fight off the threat or flee from it.
Based on this information, the correct answer is A-Endocrine.
