DIGESTIVE SYSTEM
Digestion is a process in with food turns into nutrition for your body. It will help u in many ways like it could give u energy and it could help repair cells when needed to survive. It also helps remove wastes from your body. The esophugus is a thin musculer tube that is conected with the throat to the stomach. It is also a thin wall lined with the mucas membranes. Foods and fluids go through the esophugus. "At either end of the esophagus are ring shaped muscles (the upper and lower esophageal sphincters) witch open and close" last ful review/revision August 2006 by Nicholas J. shaheen, MD,MPH. Esophageal sphincters prevent the subsstences that are in the stomach to come back to the esophagouse into the throat.
Digestion first begins in the mouth when you chew your food and chemical digestion happens. Saliva is made by the salivary glands that are found under your toungue and by the lower jaw. The saliva is the one that helps u break down the food by making it softer to disolve and easier to swallow.
You should maintain a healthy lifestyle.

Why your Liver is your Best Friend
What is the Liver? It is the large reddish-brown, meaty organ on the right side of he belly that is protected by the rib cage. It is nearly the size of a football and weighs about 3 pounds. It is made up of 2 sections, the left and right lobe and their split by the coronary ligament.
How does it function? The overall purpose of the liver is to filter the blood coming from the digestive tract before it enters the rest of the body. It also detoxifies chemicals, metabolizes drugs, and secretes bile that goes into the intestines to ensure digestion, the absorption of fats and creates proteins; for blood clotting as an example.

What conditions are dangerous for the liver?
- Hepatitis(A,B and C)- The inflammation of the liver. It can also be caused by non-infectious circumstances. Such as heavy drinking, drugs or obesity.
- Cirrhosis- A long term damage to the liver that leads to permanent scarring; which will not allow the liver function well.
- Primary Sclerosing Cholangitis- A rare disease, with an unknown cause, that causes liver inflammation and scarring in the bile ducts within the liver.
- Primary Biliary Cirrhosis- This rare disorder slowly destroys the bile ducts within the liver, leading to permanent scarring and/or Cirrhosis.
- Liver Failure- Caused by infections, genetic diseases, and excessive alcohol.
- What treatments are there for such conditions?
- Hepatitis A- Usually goes away in due time.
- Hepatitis B- Anti-viral medication (relieves the symptoms, not the virus itself)
- Hepatitis C- Depends on the factors, but on most occasions it leans towards anti-viral medication.
- Liver Transplant- Replacing your infected liver with another healthy liver.
HOW TO PREVENT DIGESTIVE DISORDERS?
You should maintain a healthy lifestyle.
- Stay active
- Don't smoke
- Maintain a healthy weight
- Enjoy high-fiber foods, start slow and build so you can adjust to the fiber fuel
Small Intestine
- Its also called the small bowel
- Its follow by the stomach and then the large intestine
- It receive bile juice and pancreatic juice
- This is where mostly where the chemical digestion takes place
- The stomach is a muscular
- It lies between the esophagus and the small intestine
- On top of the stomach lies the diaphragm
- Then behind is lying the pancreas
The Large Intestine
The large intestine is the final step of the gastrointestinal tract that conducts the important task of absorbing water and vitamins while converting eaten food into feces. Althoug it is called the large intestine this organ is actually smaller than the small intestine but has more width. The large intestine is about 5 feet in length and 2.5 inches in diameter in the body. A bunch of digested food, known as chyme, enters the large intestine from the small intestine from the ileocecal sphincter. Chyme passes through the cecum where it is mixed with healthy bacteria that have collected in the large intestine throughout a person’s lifetime. The chyme is then moved from one section of the organ to the next through the four regions of the colon. Most of the movement of chyme is achieved by slow waves of peristalsis over a period of several hours, but the colon can also be emptied quickly by stronger waves following a large meal.
The innermost layer, known as the mucosa, is made of simple columnar epithelial tissue. The mucosa of the large intestine is smooth, lacking the villi found in the small intestine. Many mucous glands secrete mucus into the hollow lumen of the large intestine to lubricate its surface and protect it from rough food particles.
Surrounding the mucosa is a layer of blood vessels, nerves and connective tissue known as the submucosa, which supports the other layers of the large intestine.
The muscularis layer surrounds the submucosa and contains many layers of visceral muscle cells that contract and move the large intestine. Continuous contraction of smooth muscle bands in the muscularis produces lumpy, pouch-like structures known as haustra in the large intestine.
Finally, the serosa forms the outermost layer. The serosa is a thin layer of simple squamous epithelial tissue that secretes watery serous fluid to lubricate the surface of the large intestine, protecting it from friction between abdominal organs and the surrounding muscles and bones of the lower torso.
Vitamin K is almost exclusively produced by the gut bacteria and is essential in the proper clotting of blood. Gases such as carbon dioxide and methane are also produced as a byproduct of bacterial fermentation and lead to flatulence, or gas passed through the anus.
The absorption of water by the large intestine not only helps to condense and solidify feces, but also allows the body to retain water to be used in other metabolic processes. Ions and nutrients released by gut bacteria and dissolved in water are also absorbed in the large intestine and used by the body for metabolism. The dried, condensed fecal matter is finally stored in the rectum and sigmoid colon until it can be eliminated from the body through the process of defecation.
The large intestine has millions of bacteria residing in its walls, but virtually all of it is needed for a healthy digestive system. Ecola, while an over ubondance of it can cause a criticaly high loss of electrolights, is used to absorb vitiam K for the body
Breast cancer can effect the organ by detroitating its walls leaving many holes where infection can grow.
1 in 15 peoplle can devolope colin cancer but is highly treatable if caught early on.
People with poor diets, infection in the intestional track, lack of dietary supplements or parasites can cause multiple symptoms to the body, such as:
Colorectal Cancer
Colonic polyps
Irritable bowel syndrom
Divericlitus
Ulcerative colitis
Dehydration
Consitapation
Dieheria
Mulitiple forms of treatment: Change of diet, medications and surgery. Surgery can result in removal of a large part of the organ but can still result in survival.
If someone is experiencing any symptoms or is unsure of their heath they or a doctor can suggest a colonoscopy. A colonoscopy involves a small, thin metal tube entering the anus and inspecting the insides of the large intestine, the tube may take samples of the organ so the doctor can conduct test on it later on.

HOw to Maintain a Healthy Digestive System
In order to maintain a healthy digestive track you must have a balanced diet and active life style. Avoid eating chili peppers on a regular bases for it is one of the worst foods that can enter your colon. If you are lactose intolerant you must avoid milk and cheese related products because it causes an irregular imbalance of calcium in the system and can result in abdominal bloating and diarrhea. Lying around and gaining weight will slow you metabolism so your body can't digest food at a proper speed and can result in several medical complications.
Some best foods to eat are yogurt, which contains many healthy bacteria for your intestine to replenish, lean meats such as chicken and fish because it's easier to digest than red meat. Whole grain is very good for the body for its high source of fiber. High active lifestyle improves the overall health in your body, including the digestive track which allows you to digest food better.

Taste
Taste is the sense that recognizes the sweet, sour, salty, and bitter qualities with the taste buds on the tongue. Taste is important as well as smell because they prepare our bodies to digest the food and provide us with information about the food and how things smell and taste. The primary organ for tasting is the mouth.Their are tastes, like spicy and creamy fatty taste that aren't considered in the general form of taste but are widely recognize. Their is 5 types of taste sweet, sour, salty, bitter, and umami. Umami is a pleasant savory meaty taste, umami is in meat, fish, vegetable, and dairy products.
Anatomy of Taste
There is four types of papillae
1. Filiform papillae: Its found all over the tongue and it thin, shaped in "v" cones and they don't contain taste buds.
2. Fungiform papillae: It is mushroom shaped, found all over the tip and side of the tongue.
3. Foliate papillae: Is a serious of fold along the sides of the tongue.
4. Circumvallate: Found at the back of the tongue and only 10 to 14 of papillae are on most people

Taste Buds
Taste buds are found on the tongue, throat, and palate. Each taste bud contain a number of taste cell. All those bumps on your tongue you see are called papillae, not all of them contain taste buds bot most of them do. Taste buds have very sensitive microscopes hair called microvilli. Microvilli send message to the brain of how something taste. An average person has about 10,000 taste buds and they are replaced about every 2 weeks. As a person ages some of the taste buds don't get replaced . An older person may only have 5,000 working taste buds. That is why food may taste stronger to you than they do to adults. One way you can reduce taste buds is by smoking. Pregnant women also become more sensitive to bitterness and less sensitive to slat. Some researchers say "kids are super-powered when it comes to taste."
Why do we need taste
We need taste because it is designed to test food and other substances before it enters the body. We also detect lots of various flavors. Some of these flavors might be good, unusual, spoiled or bad. We use our tongue and brain to taste, but if we didn't have a nose and the sense of smell we wouldn't have the ability to taste everything that we eat and drink, isn't that surprising like what does the nose have to do with all of this. In fact when you eat or drink the molecules go in your mouth, up into your throat and into the nose. There fore smell is important to.
Taste buds can be damaged
To protect your taste buds you can avoid these things
-infections
-dry mouth
-smoking
-alcohol
-spicy foods
-extreme sour foods
-some medications
but damaged taste buds can be healed.
