The human body is a complex collection of a large number of systems, which, at times, are too complex for our understanding. One of the main systems constantly provides protection against all kinds of external threats throughout life. A person may not even guess that this or that phenomenon – protective function of the organism.
Goose bumps, crying, sipping, sneezing – this is only a part of the manifestations familiar to us, the mechanism of which many do not even guess.
7 protective functions of the human body
- Sneeze
The triggering of the sneeze mechanism is associated with an overabundance in the nasal cavity allergens, germs or dust. When a person sneezes, he gets rid of everything superfluous in the nasopharynx.
160 km/h – This is the speed of air exhaled during a sneeze. On average, in one “sneeze” contains 100 thousand harmful bacteria.
Remember to cover yourself with a tissue when sneezing, this will help to at least partially prevent the spread of bacteria. By the way, if a person cannot get rid of sneezing for a long time – somewhere nearby there is a strong allergen.
- Goosebump
This protective function of the human body is aimed at reducing the heat generated through the pores in the skin, due to which the body is given the opportunity to warm up in adverse conditions.
There is a version that we inherited such a phenomenon as goose bumps from our ancestors. With a strong emotional outburst, tiny muscles tense up next to the hair follicle, which is why & nbsp; every hair is lifted. Thus, in a stressful situation, the hair on the body of our ancestors fluffed up, due to which they looked larger and more intimidating to their enemies.
- Hiccups
This protective function of the human body indicates a malfunction of the digestive system. Naturally, hiccups can occur for no particular reason or in connection with certain diseases, but often this is a signal that you should reduce the amount of food you eat.
When a person eats in a hurry, swallows large pieces of food, or simply overeats, the vagus nerve, which is closely connected with the diaphragm and stomach, is irritated.
- Tears
Due to increased tearing, the excitation of the cerebral cortex, which was caused by a cut or bruise, is reduced.
When we cry, tears also enter the nasal cavity, irrigating the mucous membrane. The latter is saturated with receptors of the trigeminal and olfactory nerves, which transmit signals directly to the brain, distracting it from the main source of irritation – pain.
- Sipping
Sipping is also a kind of body defense mechanism, despite the fact that we are able to control it. Thus, the human body prepares for physical activity that awaits it throughout the day – muscles warm up after sleep, blood circulation is restored, and mood – getting better.
In addition, according to scientists, sipping can improve tactile and taste sensations.
- Myoclonic seizures
Probably, everyone has come across this defense mechanism of the human body. Now you are already starting to fall asleep and suddenly the body, as if they are being shocked, the muscles are sharply and strongly contracted so much that you are thrown up.
Myoclonic convulsions occur because the sudden decrease in breathing and muscle relaxation during sleep are mistakenly perceived by the brain as a dying state. This is a kind of impulse with which the brain tries to save you.
- Skin swelling from moisture
Swelling skin after prolonged bathing is also a protective function of the body. Since the body feels that it has encountered high humidity, and where it is humid – so slippery.
Change in the skin on the fingers is due to the fact that in this way grip with smooth surfaces is increased. That is, the body is trying to create conditions that will not allow slipping.
