When did the term stress enter scientific literature?

Answers

Answer: 1930s

The term stress as it relates to the human condition first emerged in scientific literature in the 1930s, but it did not enter the popular vernacular until the 1970s (Lyon, 2012).

Hope this helps :)

The term stress entered scientific literature in the 1930s.

The term was first used by Hans Selye, a Hungarian-Canadian endocrinologist, to describe the general adaptation syndrome, which is the body's response to stressors. The general adaptation syndrome is a three-stage process that includes alarm, resistance, and exhaustion. Selye's work on stress was groundbreaking, and it helped to pave the way for the field of stress research.

Today, stress is a well-studied phenomenon, and it is known to have a significant impact on physical and mental health. The alarm stage is the initial response to a stressor. The resistance stage is the second stage of the general adaptation syndrome.  The exhaustion stage is the final stage of the general adaptation syndrome. If the stressor is too severe or if the body is not able to adapt, the body will eventually reach a state of exhaustion.

Process of chewing.......

Answers

Answer:

When you first put a piece of food in your mouth, it is first grinded by your teeth, then saliva comes in to help you break down your food, the more you chew the more digestive enzymes occur, these enzymes are extremely important, they help your body take in nutrients from what you eat. This is why it's important to chew your food thoroughly before you swallow,

Chewing or mastication is the process by which food is crushed and grounded by teeth. It is the first step of digestion, and it increases the surface area of foods to allow a more efficient breakdown by enzymes... After chewing the food ( now called a bolus) is swallowed. Hope this helps.
