Your Body’s Response to Emergency How does the body prepare for emergencies? The answer lies in the Sympathetic Nervous System (SNS). It is the branch of the Autonomic Nervous System (ANS) that controls the body’s reaction to physical and emotional stressors. The sympathetic branch activates the glands and organs that defend the body against attack. It is called the fight-or-flight response. This is a primitive response designed to protect from danger. When danger is perceived‚ the sympathetic

Homeostasis Homeostasis Is a technical term for the process of maintain a constant internal environment despite external changes. The internal environment‚ compromises; blood‚ tissue fluid‚ body cell contents and all the metabolic processes taking place. Constant in this instance is not absolute or fixed it is much more flexible and dynamic as it refers to the physical and chemical composition being kept within a limited range or variables for maximum efficiency‚ well-being of the whole body and

M2: Discuss the probable homeostatic responses to changes in the internal environment during exercise. D2: Evaluate the importance of homeostasis in maintain the healthy functioning of the body. Homeostasis is the process which the body internally is kept relatively stable despite changes in the environment. Your body is able to adapt to several conditions. For instance‚ average human body temperature is 37°C‚ varying slightly from person to person. When the temperature outside drops to 30 degrees

1. Why did Allen’s heart rate and blood pressure fall in this time of emergency (i.e. at a time when you’d expect just the opposite homeostatic response)? Pg. 969 This occurred because Allen’s spinal cord has decreased perfusion due to damage‚ and a broken vertebral bone. Also‚ there has been a disruptions of the sympathetic fibers of his autonomic nervous system therefore it can no longer stimulate the heart. Allen likely has spinal shock. 2. Upon admission to the hospital‚ Allen’s breathing
