Final answer:
A person's ability to survive an emergency, and to survive it without any permanent damage, relies on physiological processes, including the intake of vital elements and the body's ability to think, learn, and remember.
Step-by-step explanation:
A person's ability to survive an emergency, and to survive it without any permanent damage, relies on the chain of physiological processes that the body must maintain.
Humans cannot survive without vital elements such as oxygen, water, carbohydrates, lipids, proteins, vitamins, and minerals. The body also requires specific atmospheric pressure and blood pressure to ensure proper respiration and circulation.
In addition, a person's ability to think, learn, and remember plays a vital role in responding to and surviving an emergency situation.
