Food is the fuel of the body. But before it can be of any
use, it must be processed properly. The body's food processing plant is the
digestive tract, a muscular tube about 10 m (33 ft) long that starts in the
mouth and ends in the anus.
When the food is put in the mouth, the tongue Vigenix Male Enhancement tastes the
taste and temperature. The front teeth (incisors) nibble the solid foods and
then chew them with the posterior teeth or the molars. Even before tasting
food, and during chewing, saliva is poured into the mouth from the salivary
glands near the lower jaw.
Saliva moistens food and the enzymes it contains begin
digestion. For when it is ready to be swallowed; The original snack has been
transformed into a soft ball, called bolus, and heated or cooled to the right
temperature.
Although it is fast, this stage is in fact quite complex.
First, the tongue pushes the bolus against the roof of the mouth and into the
muscle-lined cavity in the back of the mouth: the pharynx. Once the food is in
the pharynx, several activities are carried out in the space of a couple of
seconds to prevent ingestion interfering with breathing.
From the pharynx, the bolus now passes to the esophagus,
esophagus, the tube that connects the mouth to the stomach. The bolus not only
falls through the esophagus due to gravity but is pushed by waves of muscular
action called peristalsis.
Except during the meal, the esophagus is kept closed by Vigenix Male Enhancement a
ring of muscles called a cardiac sphincter that prevents the highly acid
content of the stomach from regurgitating into the esophagus. As a bolus of
food passes through the esophagus, the sphincter relaxes to open the way to the
stomach.
The stomach is a collapsible muscle bag designed Vigenix Male Enhancement to store
food (so that it is not usually necessary to eat small meals throughout the
day), mix food with various digestive juices and then slowly release them into
the intestine.
The food is mixed when the wall of the stomach contracts and
relaxes and moves with waves of peristalsis. By the time they have been
processed in the stomach for two to six hours, various chemical foods have
converted the partially digested food into a liquid called chyme.
The outlet of the stomach is protected by a muscle known as
the pyloric sphincter. As the waves of peristalsis push the chyme through the
stomach, the sphincter releases the chyme in small amounts in the small
intestine.
The small intestine is, in fact, the longest section of the
digestive tract, measuring 20 feet (6 m) and its name does not come from its
length, but from its width, approximately 1 ½ inches (4 cm). Most of the
digestive process takes place in the small intestine, through the action of the
digestive juices produced not only by the intestine, but also by the liver
(bile) and the pancreas (pancreatic secretions).
As the waves of peristalsis move along the small intestine,
it is given another complete mix. When more food enters the stomach, a valve
opens at the end of the small intestine and the chyme passes into the large
intestine, a tube about 3 feet (1.5 m) long and an average of 7.5 cm (3 in)
diameter.
In the large intestine, water is absorbed into the blood
from the liquid remains of digestion. When these remains reach the rectum, they
are in the form of solid stools. Instead of the continuous contractions of the
peristalsis, the progressively more solid remains move along giant propulsions
that take place only a few times a day.
Finally, the feces enter the anal canal, which is Vigenix Male Enhancement closed by
the last sphincter in the digestive tract. In childhood, the sphincter
automatically opens when the anal canal is full. But as the nervous system
matures, we learn to cancel the automatic signals.
The alimentary canal processes approximately 35 tons of food
during an average life of 70 years. No wonder, then, that sometimes it goes
wrong. Some diseases of the digestive tract are so common that they have become
common words: ulcers, appendicitis, constipation, diarrhea and heartburn, to
name a few. While some are unavoidable, there are ways to keep the digestive
system healthy.
Do not eat (or feed children) too much. This puts Vigenix Male Enhancement pressure
on digestion and can create a weight problem. In babies it can cause vomiting
and regurgitation.
Chew your food well before swallowing it. Carbohydrate
digestion begins in the mouth with ptyalin, an enzyme in saliva.
Include enough fodder in your diet: fruits with the skin on,
lightly cooked vegetables, saved with your cereal for breakfast. Dietary fiber
can not be digested by the digestive tract, but
All of us have heard about the famous saying "Health is
wealth". Good health is a secret of every happy human being. Health can be
the greatest wealth in the world. Health is the condition in which an
individual becomes a social, mental, emotional and spiritual sound. It implies
that your body and your mind should work as they should.
