Why tears while cutting onions
WHY DO WE GET TEARS IF WE CHOP THE ONIONS
It is a very interesting thing that when we cut the onions we will get tears but it doesn’t occurs in case of any other vegetable. The tears you shed when chopping onions aren't emotional ones. We release tears because of sulfur gas.
Sputum duing cough
HOW THE SPUTUM IS FORMED WHEN WE COUGH
The involuntary expulsion of air from the lungs with a characteristic sound is called as cough. It is used to respond against the noxious substances and it is also used in maintaining the air passages in the respiratory tract.
Skin wrinkles
Skin wrinkles in old age
In old age, the elastic fibers of the skin undergo senile generation for which the elasticity of the skin is lost, and with the wasting of the muscles, the skin cannot adapt itself to the reducing girth, and as a result, the skin becomes wrinkled, a feature of the old man’s skin.

Hiccups' Mechanism
Why Hiccups..?
Hiccups will be caused by two nerves, Phrenic nerve (a nerve in the diaphragm) and the vagus is the tenth cranial nerve, which is also known as pneumogastric nerve. when there is no obstruction of the airways tract, as these nerves are stimulated, and they take response to spinal cord. Eventually the spinal message to the brain through the chest cavity (thoracic cavity) and neck.
Irritation of any of these nerves can cause the diaphragm ( a thick sheet like structure present underneath the lungs which used to cause vaccum in the lungs at the time of respiration ) to undergo involuntary contraction and it causes the pulling of air into the lungs. The pulling causes the throat muscles to show some reflex.so,the trachea is closed with a sound “ HIC “. Since it is a disturbance in the respiratory tract, it can be cured by few simple techniques:
1) Drinking water stops hiccups, this is due to the location of the digestive tract just adjacent in the airways. If we take a little water into the digestive tract before it reaches the stomach into the esophagus it shows some rhythmic contractions called PERISTALTIC CHANGES .. Because of these movements can be adjacently positioned windpipe (trachea) gets moved so that it can open and hiccups are controlled.
2) Sometimes our elders suggest us to stop breathing for few seconds .. during the time the respiratory tract may have adjusted themselves so we can get rid of hiccups.

Body Odour, Lets know about
Body Odour
Our skin is included in the integumentary system of our major metabolic reactions.The integumentary The system includes the skin and its derivatives such as hair, nails, horns, etc. It also includes the sweat glands that is present inside the skin. The sweat glands present in our body is called as apocrine glands and eccrine glands.
The apocrine sweat glands are stimulated by the secretion of hormones from the adrenal glands of kidney. The name of the hormone adrenaline. Sweat is generally released to control the body surface temperature. When the outdoor temperature rises, so the body is stimulated to release sweat so the skin is protected from high temperatures.
The smell of sweat due to bacterial action.
East Asian peoples have fewer apocrine glands when compared with European or African people. That is why people are less susceptible to BODY ODOR.
Eccrine glands are also called as merocrine glands. Their secretions are useful for thermoregulation.Thermoregulation done by inclusion of NaCl in the channels. It is controlled by the hypothalamus in the brain.

The sweat glands present in our body is called as apocrine glands and eccrine glands.
- Apocrine glands are composed of a coiled secretory portion
- Eccrine glands produce a clear, odorless substance consisting of water and salt (sodium chloride).

Skin Soaked..? What happens then..?
What happens when skin soaks
When our hands are soaked in water for a long time we will get some folds on our skin….
If we get wet for a long time or if we close our body parts by means of gloves, masks etc. we observe that particular part of our skin folded. There are few reasons for such behavior.
Skin is covered with thin layer of sebum which is a waxy coating present on the skin. It is generally used to keep our body moisture and is also protective in nature. If you spend a long time in water, the sebum layer on the skin washes away, epidermis start to soak up water.
As the outermost layer (epidermis) absorbs water, it grows in volume. But the layer of the skin present underneath the epidermis (dermis) doesn’t expand along with it. The epidermis is tightly attached with dermis.
So, even though outer layer is expanding, it forms folds because of stiff dermis and it wrinkles.

Things that commonly happen to you, you need to know
SNEEZING
It is a sudden relaxation of the diaphragm together with the intercoastal muscles that expand our lungs and abdominal muscles contraction. This results in a mass-compression effect of the lungs on a short onset and causes a violent expulsion of air in the form of the SNEEZE.
The sneeze is a result of a noxious or allergen that enters the upper respiratory tract and is detected by neural cells present there. This sends out signals to the thalamus and the thalamus sends out signals to the muscles mentioned above and produces the sneeze.
Why BALDNESS..? **
It is also called as ALOPECIA (Scientific name of BALDNESS). In androgenic alopecia, the testosterone is acted upon by enzymes 5a reductase converts it into Di hydro testosterone (DHT).
The scalp is very sensitive to this hormone, the presence of DHT cause the hair follicle to shrink. This will eventually results to the loss of hair and inability to grow new strands.
WHY DO WE GET SICK IN WINTER**
With the approach of autumn, slight chill in the air after the relentless heat of the summer. Cooler temperatures and shortening days also signal the start of the flu season.
Exposure usually occurs in one of the following ways:
(1) By oral inoculation.
(2) By inhaling droplets of our nasal vaccine.
While we have much control over the air we breathe, we can control a large extent, what we touch.
Decreased amount of any light produces less VITAMIN-D. New research is revealing that this vitamin is instrumental in maintaining a healthy immune system. Our flu season is November to march. Vitamin-D is able to kill the bacteria that causes TUBERCULOSIS. Increasing vitamin-D intake during the winter months is safe.
There are two forms of vitamin-D:
D2 –Ergocalciferol—Doesn’t appear in humans.(Salmon, Raw cow's milk, Sun light, Cod liver oil)
D3- Cholecalciferol—Made in the body.
BRUISES
Bruises occurs when blood vessels under the skin damaged, the blood capillaries leak blood under the skin giving purplish or red bruising results. The colors of the bruise will change as the swelling dies down and the bruise fades.
The amount of fat covering your body may be a contributing factor if you tend to bruise easily. If you do not have an adequate layer of fat, then bruises will sometimes appear with the slightest knock.
Muscle groups around the vital organs to create warmth by stimulating the muscles to release heat as they work.The primary motor centre for shivering is located in the Hypothalamus and is activated by cold signals from the skin and spinal cord.In the case of a reaction to the cold, drop in the body temperature will signal the HYPOTHALAMUS. It stimulates the muscles to form heat. Shivering is an Autonomic nervous response to generate heat.
Shivering is a response to HYPOTHERMIA.
- Hypothermia is a condition in which drops the body temperature to normal body temperature.
- Hyperthermia is an increase in body temperature than normal.
WHY DOES FEVER OCCURS **
When bacteria, virus or fungi invade our body. When our body gets infected, its natural response is to activate cells in the immune system. These cells are called White Blood Cells(W.B.C). When they are activated , they fight these bacteria in many ways, one of which is to raise the body temperature.
When the virus or bacteria enters the body system, they produce toxins that can directly set the body’s temperature up. Meanwhile, these toxins also trigger the W.B.C. to emit substances that can also increase the body temperature.
Fever that is persistent for a longer period of time is not good. There is a tendency for a disorder in the brain, when the temperature continues to be high.
MECHANISM OF HICCUPING
Phrenic nerves of diaphragm and vagus nerve take sensation to spinal cord. This will pass through thoracic cavity and neck. Irritation of any of the nerves involved in this loop can cause the diaphragm to undergo involuntary contraction or spasm, pulling air into the lungs. This triggers a reflex in the throat muscles. So, the trachea is closed off to give “ HIC “ sound. How the drinking of water cures the respiratory defect is explained as :
GAS FORMATION
Reduced digestion or absorption by the small intestine allows increased amounts of sugars and carbohydrates to reach the colon where greateramounts of gas formation takes place.
