About Water Content Of Saliva And Saliva

About Water Content Of Saliva And Saliva

Saliva, saliva, or saliva is a clear liquid produced in the human mouth and some animals. Saliva appeared to have the content of compounds that have various functions for our bodies. Besides, he also has various functions that were previously unknown to us.

Womb
In animals, saliva is produced and secreted from the salivary glands. As for abortion are:
* Electrolytes: (2-21 mmol / L sodium, 10-36 mmol / L potassium, 1.2 to 2.8 mmol / L calcium, 0.08 to 0.5 mmol / L magnesium, 5-40 mmol / L chloride, 2-13 mmol / L bicarbonate, 1.4 to 39 mmol / L phosphate)
* The mucosa, which mainly contain mucopolysaccharide and glycoprotein
* Antibacterial compounds (thiocyanate, hydrogen peroxide, and immunoglobulin A)
* Some kinds of enzymes, including alpha-amylase (EC3.2.1.1), lysozyme (EC3.2.1.17), and lingual lipase (EC3.1.1.3).
Amylase and lipase in a row to start digestion of starch and fat before the food is swallowed. These enzymes work optimally at pH 7.4. Lingual lipase has a pH optimum ~ 4.0, so it will not be active if it has not entered an acidic environment. Lysozyme plays a role in bacterial lysis. Saliva also contains human saliva acid phosphatase A + B (EC3.1.3.2), N-asetilmuramil-L-alanine amidase (EC3.5.1.28), NAD (P) H dehydrogenase-quinone (EC1.6.99.2) , laktoperoksidase saliva (EC1.11.1.7), superoxide dismutase (EC1.15.1.1), glutathione transferase (EC2.5.1.18), class 3 aldehyde dehydrogenase (EC1.2.1.3), glucose-6-phosphate isomerase ( EC5.3.1.9), and tissue kallikrein (EC3.4.21.35). The existence of these products sometimes result in saliva smells.

Humans spend approximately 700 ml of saliva per day.
Some people might find sterile saliva or disinfectant, so believe that saliva will more quickly heal wounds. In fact, the mouth is a hotbed of germs and bacteria. There are over 600 types of bacteria in the mouth and saliva that can cause infection. As quoted from the following MSN secret behind saliva:

What is in saliva
Most of saliva is water, but also contains electrolytes, bacteria, viruses, fungi, secretions from the nose and lungs, cells from the lining of the mouth and about 500 proteins. Of course, the contents of saliva also depends on what you put into the mouth, such as food debris. Components toothpaste also commonly found in saliva. The content of saliva every person is different.
What can be known from saliva?

Of saliva, can be obtained from DNA samples. In fact, although saliva does not contain the DNA of cells, but cells from the lining of the mouth can be found in saliva samples. Saliva is also another clue to the identity of a person's menungkapkan. Saliva may reveal what has been eaten and drugs that may be consumed, such as cocaine, marijuana and barbiturates. Scientists can also use saliva samples to show how much of certain drugs in the body.

The scientists also want to be able to use saliva as a tool to detect the disease, because it is much easier, and in many cases more secure. HIV testing is one of the saliva test which is used as
sample, although the blood test is still the standard way to test for HIV.

What are the functions of saliva
Some people do not realize how important functions of saliva, namely:
  • . Break down food in the mouth, so it can be perceived by the tongue and is more easily digested by the stomach.
  • . Clean food and dead cells from the lining of the mouth
  • . Binds food into a ball so that it can be swallowed
  • . Clean food and bacteria from the teeth
  • . Prevent dry mouth lining
  • . Destroying or preventing the growth of certain fungi
  • . Neutralize acids from foods and beverages
  • . Help regenerate the damaged tooth enamel, due to calcium and phosphorus levels

How much amount of saliva?
Goodson
estimate the average person produces about half
liters of saliva a day. But of course this number is also
influenced by several factors, among others:

  • . Genes
  • . Time (saliva production slows down drastically at night)
  • . Much water you drink
  • . Was chewing gum or sucking hard candy (both increase the production of saliva)
  • . Smelling something interesting (also increase saliva production, which is why there is the term 'delicious')
  • . More than 400 medications cause a decrease in saliva production
  • . Age production (saliva decreases with age)
  • . conditions or diseases that affect the production of saliva,
  • .such as Sjogren's syndrome, or are undergoing radiation therapy.

Saliva Water For Health Benefits

For some people, often looks disgusting saliva. Though the water that comes from the mouth it has an important role for health Manuia. Saliva or saliva are mostly produced by three major glands the parotid gland, sublingual gland and submandibular gland. The volume of saliva that is produced varies from 0.5 to 1.5 liters per day depending on the level of the stimulus.

Citing Guyton & Hall Textbook of Medical Physiology in, saliva or saliva containing two types of expenditure or major secretion of fluid containing the secretion serus ptyalin (an alpha amylase) which is an enzyme to digest carbohydrates and mucin-containing secretion of mucus for lubrication purposes or surface protection is largely produced by the parotid gland.

The liquid type of mucus that is secreted or released every second all the time except when sleeping less production.

In terms of digestion, saliva plays a role in helping the digestion of carbohydrates. Carbohydrate or starch is broken down sebaagian have started small in the mouth by the enzyme ptyalin. The enzyme in saliva that break down starch (amylum) into disaccharides maltose and other small glucose polymers.

For example, when you chew the rice was tasteless in the long run will taste sweet due to the rupture of starch into maltose that tastes sweet.

In addition to the digestive saliva also plays a role in oral hygiene. Salivary secretion, especially the type of mucus is important in maintaining healthy oral tissues. Oral cavity contain pathogenic bacteria or germs (harmful) that can easily damage tissue and cause dental caries (tooth decay).

Saliva also prevents damage in several ways. First, the flow of saliva helps rid itself of bacteria or pathogenic bacteria are also particle nutritional foods that provide metabolic support for the bacteria itself.

Second, saliva contains several factors that destroy bacteria are one thiocyanate ion and some fluids, especially proteolytic lysozyme that destroys the bacteria, helping thiocyanate ions kill bacteria, digest food particles and saliva contains antibodies that destroy the bacterial proteins.

In addition to working for health in the body, saliva is also believed to provide benefits to the outside of the body.

Since the days of dahalu, instinctively when your fingers are injured by knife scratches, you will suck the wound with his mouth. Animals too. Eg cats, monkeys, and dogs, used to wash the body with saliva when the wound.

Prophet Muhammad as narrated by Bukhari, Muslim recounts, if any friend who scratched and wounded, then he read a prayer and then spit attached to his right hand, then rubbed in the wounds of that while reading the prayer, which reads "Allahumma ROBBINNAS ADZHABILBAS ISYFI ANTASY- Syafii SYIFA LAA-A-illa SYIFA UKA YUGODIRU SAQOMAN LAA ".

Meanwhile, based on studies that have been conducted in Japan in 2001, as quoted by cbn.com, saliva contains 40 to 50 proteins. Each protein has different functions. One protein to ward off dust, light, and chemicals. Of the 50 proteins that in it there are three proteins that are specific to microorganisms.

Top efficacy that is, saliva is believed to be beneficial for eye disorders, such as cataracts, nearsightedness and close, or eye disorders such as injuries hit, hit by blunt objects and sharp objects. Read More...
