Preparing for Fight or Flight Response

When a human body senses a scary or dangerous situation, it prepares itself for a fight or flight response. The sequence of changes that take place in the human body to protect itself are as follows:

1. Activation of the Sympathetic Nervous System
The sympathetic nervous system is activated, which triggers the release of adrenaline and noradrenaline hormones from the adrenal glands. These hormones prepare the body for a fight or flight response.

2. Rapid Breathing
The breathing rate increases to provide more oxygen to the body. The rapid breathing helps to increase oxygen intake and carbon dioxide elimination.

3. Increased Heart Rate
The heart rate increases to pump more blood to the muscles and other organs to prepare for action.

4. Dilated Pupils
The pupils dilate to allow more light in, which helps to enhance visual acuity and sensitivity.

5. Increased Blood Sugar Levels
The liver releases glucose into the bloodstream to provide energy to the muscles and other organs to prepare for action.

6. Muscles Tense
The muscles of the body tense up and become ready for action. This prepares the body to fight or flee from danger.

7. Decreased Digestion
Digestion slows down, and blood flow is redirected to the muscles and other organs that need it the most.

8. Increased Sweating
Sweating increases, which helps to regulate the body temperature and remove waste products.

9. Increased Alertness
The brain becomes hyper-vigilant, and the senses become more acute. This helps the body to detect potential threats and respond to them quickly.

Conclusion
In conclusion, the human body has a complex and sophisticated system for protecting itself from scary or dangerous situations. The fight or flight response is a natural response to stress, and it helps humans to survive in threatening situations.

When an organism is in a scary or dangerous situation, adrenal glands secrete a hormone called adrenaline into the blood. .This hormone is transported all throughout the body. When this hormone is secreted a sequence of changes takes place in the body.

1 The heart starts beating faster. As a result more amount of oxygen is supplied to the muscles.
2 The breathing rate is increased because of the contraction of diaphragm and rib muscles.
3 It also increases the blood pressure.
4 Blood is diverted to organs such as heart, brain skeletal muscles because the blood vessels.
