7,599 Questions
Where does enzymatic digestion begin?
enzymes start the process of digestion in the mouth. they are located more specifically in saliva which is located in the salivary glands.
How can indigestion be helped using neutralisation?
indigestion needs to be neutralised with a medium strength base and magnesium oxide has one .
What type of food molecule is broken down to glucose by digestion?
Sugars and starches are broken down into glucose.
Is the pancreas part of the digestive tract?
No. The digestive tract consists of the tube that makes up the esophagus, stomach, small and large intestines, rectum, and anus. The pancreas (and liver) are accessory organs which, along with the digestive tract, make up the digestive system.
Food that leaves the stomach is in the form of a thick liquid called?
The liquid mixture of food in the stomach is called chyme.
How does the digestive System interact with the skeletal system?
It helps it by protecting all your internal organs.
What is the process called when nutrients go from the digestive system and into the bloodstream?
Digestion
Most chemo and radiation treatment is based on the fact that the cancer cell is somewhat more sensitive to the poisons and radiation than the healthy cells. So they poison you ... very exactly.
Skating this close to being killed upsets your body systems a lot, but since the dose is so exactly controlled you get over it but your little buddy cancer cells bite the bullet. Sickness and hair loss is a side effect.
Latest developments use materials that are non-toxic and tasty to the cancer cells so they absorb a lot more than non-cancer cells. Once they're full a triggering agent or light activates the chemicals in the cancer cells. They die. The normal cells didn't build up the same concentration so they live.
All in all not nice. But, between a hard option and no chance at all I've always opted for the best bet to stay in the game.
A little more...Generally speaking, malignant cells reproduce VERY quickly -- moreso than other cells in your body. Chemo is targetted at killing off the fastest growing cells. Besides malignant cells, other fast-reproducing and fast growing cells include hair, finger and toenails, The GI lining, etc. In other words, all the places that chemo hits you.Post-operative chemo and/or radiation are really necessary almost every time. As an example with breast cancer, a mastectomy with clean margins will yield the patient as being cancer free, but in higher stages of this disorder, not following up with chemo will result in a clonally identical cancer to re-emerge within 5 years about 85% of the time.
Chemo is a difficult phase and it's easy to let people who mean well convince you it's not. The bad news is that chemo is difficult. The good news is that it gets easier and then you're done. It can significantly increase your chances for long-term, non-problematic survival.
What is the digestive juice which has no enzymes?
Bile. It's produced in the Gall Bladder and is made of dead red blood cells. It emulsifies fat.
What organ where nutrients are absorbed into the bloodstream?
Nutrients are absorbed throughout the digestive process. Specific nutrients are absorbed in the stomach and large intestines, but the majority of nutrients are absorbed in the small intestines.
it is produced by mixing food from the oesophagus with acids from the stomach to produce a thick semi-liquid.
What nutrients are absorbed in the small intestines?
They're absorbed so that you can actually gain some nutritional value from food you eat.
--Where are they absorbed? Nutrients are absorbed throughout the entire small intestine, with most of it happening in the duodenum and decreasing as you move further towards ileum. The entire small intestine functions to absorb nutrients from food, whereas the large intestine is more for resorption of salts and water and to remove wastes.
What is pepsin responsible for?
1. Pepsin is the important digestive enzyme of the stomach.
2. Pepsin can essentially digest any protein in the diet.
3. Lacking sufficient pepsin, protein foods are poorly penetrated by other digestive enzymes further on and are thus poorly digested.
What diseases are associated with the digestive system?
some diseases associated withe the digestive system are:
Colon and Rectal CancerColon and Rectal cancer is also referred to as colorectal cancer. This type of cancer is a malignant cell that is found in the colon or rectum region of the body. The large intestine is made up of the colon and the rectum. Colon and rectal cancers share so many common features that they are referred to as the same cancer which is how the name colorectal cancer came about. Stomach CancerStomach cancer is also called, gastric cancer. This cancer affected approximately 21,700 Americans during 2001. The majority of those individuals were in their 60s and 70s. The risk factors for developing stomach cancer are Helicobacter pylori infection and a diet that consists of the following: eating large amounts of smoked foods, salted fish and meat, foods that are high in starch and low in fiber, pickled vegetables, and foods and beverages that contain nitrates and nitrites. DiarrheaDiarrhea is watery stool, or an increased frequency in stool, or both as compared to the normal amount of stool passed by the individual. Diarrhea can be short-term or it can be related to a bacterial or viral infection, or it can be long-term which is usually related to a functional disorder or intestinal disease. Diverticular DiseaseThis disease occurs in small pouches that bulge out in the colon. It is an inflammation or infection in the pouches. Gas in the Digestive TractYou get gas in your digestive tract by swallowing air or during the breakdown process of certain foods by the bacteria that is present in the colon. Everyone has gas. It can be uncomfortable and certainly embarrassing to pass the gas. The average person produces 1 to 3 pints of gas a day and pass gas through their rectums about 14 times each day. HeartburnHeartburn is what most of us get from time to time. Chronic heartburn is a digestive disorder called gastro esophageal reflux disease (GERD). GERD is caused by gastric acid that flows from the stomach and into the esophagus. HepatitisThis is an inflammation of the liver that can result in liver cell damage. There are two types of hepatitis - acute and chronic and six main types of the hepatitis virus. Inflammatory Bowel DiseasesThere are several different diseases that fall under this category all of which require a doctor for treatment. Ulcerative colitis and Crohn's disease are two of these diseases. Irritable Bowel SyndromeIrritable bowel syndrome - more commonly referred to as IBS - is an intestinal disorder that causes cramping, gassiness, bloating and changes in the bowel habits of the individual with the disorder. Lactose IntolerancePeople with lactose intolerance lack an enzyme that is called lactase. This enzyme is needed by the body to digest lactose. Lactose is a sugar found in milk products. Adults and children are affected by this intolerance. Digestive diseases or injuries to the small intestine cause this intolerance. Individuals can experience different symptoms but the common ones are: cramping, bloating, gas, diarrhea, and nausea. The symptoms will worsen when larger portions of milk products are consumed. Stomach and Duodenal UlcersUlcers are open sores or lesions. They are found in the skin or mucous membranes of areas of the body. A stomach ulcer is called a gastric ulcer and an ulcer in the duodenum is called a duodenal ulcer. Lifestyle, stress and diet used to be thought to cause ulcers. These factors may have a role in ulcer formation; however they are not the main cause of them. Scientists now know that ulcers are caused by hydrochloric acid and pepsin that are contained in our stomach and duodenal parts of our digestive system and that these acids contribute to ulcer formation.
What is the name of the wave like constraction that propel food along the gut?
Peristalsis is the process by which smooth muscle moves a mass of food (called the food bolus) through the digestive system.
There is circular smooth muscle and longitudinal smooth muscle in the digestive tract. Contraction of circluar smooth muscle keeps the food bolus from moving "backward" along the digestive tract by decreasing the diameter of the tract behind the bolus. Contraction of the longitudinal muscle in the digestive tract propels the food bolus "forward" in the digestive tract.
Can the human body digest a metal swallowed?
yes if its not ponty or to big like a tiny marble u can swallow
What could cause you to get nauseated often?
It is important that you see a doctor. There may be a few possibilities such as migraines, diabetes, hypoglycemia, and pregnancy if you are sexually active. It is also possible that you may have some sort of thyroid imbalance.
What is the last place where the digestion occurs?
ILLIUM
Goes deudenum, jejenum, ILLIUM, then large bowel
What is the difference between a wolf's digestive system and a human's digestive system?
since wolves are carnivores, their digestive system would be less complicated, humans need extra parts, like herbivores, to hold the bacteria required to break down and digest cellulose since we eat fruits and veggies to get all that cellulose in our system in the first place, that why if dogs want to throw up, they eat grass, their digestive system can't break it down and just rejects it.
or at least that's the best i can give you...
There is no enzyme that assists in the breakdown (digestion) of glucose like you would see in sucrose (a disaccharide sugar). Glucose is a monosccaharide and is generally used in the body to make ATP in the glycolysis pathway. In this path glucose is used to make 2 net ATP. The first step in this path hexokinase is the enzyme that acts as the catalyst to phosphorylate glucose to glucose-6-phosphate. If you are asking about glucose or alpha-d-glucose as a polymer or starch then that would be alpha and beta amylase which can turn a chain of the glucose into monoscaccharides of glucose and maltose.

How are carbohydrates digested?
Starch digestion begins in the mouth. As food does not remain long in the mouth, only a little starch is digested by salivary amylase to maltose. No digestion of carbohydrates occurs in the stomach; only proteins are digested in the stomach. In the small intestine, starch is digested by pancreatic amylase into maltose, which is digested by maltase into glucose. Lactose is digested by lactase into glucose and galactose. Sucrose is digested by sucrase into glucose and fructose.The end products of carbohydrate digestion are simple sugars (glucose, fructose, and galactose) which can be absorbed. Cellulose is not digested in the humans' gut.
Yes.
The anus bleeds from irritation of small capillaries that are in the walls of the rectum. A hard bowel movement can cause a slight tear, which will heal on its own. Hemorrhoids also cause bleeding. Hemorrhoids can be internal, or external. If external, they will burn and itch. Over the counter creams can help reduce the pain.
You need to see a doctor IF:
- you have more than a very small amount of blood
- your stools are black
- if you are regularly constipated
- if hemorrhoids continue to bother you even after over the counter creams
- if hemorrhoids become worse or bleed
- if you have rectal-anal pain
- if the bleeding occurred after anal sex, even with a 'toy'
Into which part of the alimentary canal does the pancreas secrete pancreatic juice?
The duodenum which is part of the small intestine.
What is the semi-digested food inside the stomach called?
CHYME...the food that enters the stomach is stored and mixed with the nzyme pepsin and hydrochloric acid to form a soupy material..
Where does digested food enter into the blood?
once almost fully digested the food moves through the inestines, while the waste moves on to be excreted, the nutrients and such which are a great use to the blood cells are absorbed through the walls of the intestines. Thus into our bloodstream. And that first you need to chew and it will go to your blood stream
