Which team refers to the loss of intestinal peristalsis?
Ileus is a functional rather than mechanical obstruction of the bowel. It is a lack of propulsive peristalsis (wave-like movement) of the bowel. It stops the movement of bowel contents downward. There is abdominal distention and an absence of bowel sounds.

Why does your stomach have folds in its walls?
Inside the small intestine thair are lots of hair like things that help with digestion. Now if you get a peice of paper (recycle after please) and fold it so that it ends up as a strip. now if you look it from above the size of the paper has shrunk. the small intestines use the same idea so the can fit more hairs into a smaller area
What is the name of the pipe that food goe down after you swallow it?
The name of the tube that food goes down when you swallow is called your esophagus.
Yes Maltose can be digested by the human body. Cellulose can not
What describes the process of starch digestion?
When starch enters the mouth, it is acted upon by salivary amylase which is an enzyme that breaks starch down into maltose. It is not fully digested yet.
In the stomach, low PH levels caused by the hydrochloric acid denatures the salivary amylase, rendering it useless for starch digestion. The starch remains in the stomach, until it's churning action turns starch into chyme (liquefied food) The purpose of this is to increase the surface area to volume ratio, so as to increase the efficiency of enzyme action.
The starch leaves the stomach, and enters the small intestine. In the intestine, it is acted upon by the intestinal amylase, and the pancreatic amylase, which fully breaks down the starch into maltose. Afterwhich, the maltose is acted upon by maltase, which breaks it down into glucose. When this is done, it can be absorbed easily by the villi into the bloodstream.
What process allows you to swallow your food while standing on your head?
You can do this through the muscular contractions that are happening in your esophagus.
What role does bile salt play in digestion?
Bile salts break down fats into very small particles so that the lipases (fat enzymes) have a lot of surface area to work on. If the gall bladder is removed, this function is reduced and the fats are passed through without being digested.
You have bile salts called as sodium taurocholate and sodium glycocholate. They are secreted by the liver in the bile. They act as the agents, which emulsify the fat. That means the fat is broken down to very small spherical particles. This greatly increase the surface area of contact between the lipase enzyme and fat. This helps in digestion of the fat. The bile salts are reabsorbed in lower part of the intestine. So the bile salts are recycled. This process is called as 'Enterohepatic' circulation.
Which organ structure is the bile duct?
Bile is produced in the liver and stored in the gall bladder.
What are five organs that make the digestive system?
The digestive system includes the gastrointestinal tract, liver, pancreas and gallbladder. The GI tract includes the mouth, esophagus, stomach, small intestine and large intestine.
Where is the bile stored and concentrated?
Bile is stored and concentrated in the gallbladder, although it is produced by the liver. Then it goes to the duodenum (part of the small intestine) when it is needed for digesting lipids (fats).
What is the action of breaking down food into smaller pieces?
Mechanical digestion, which is accomplished by chewing, and the phsyical movements of the stomach. More specifically, chemical digestion which is accomplished by the action of acids in the stomach and digestive enzymes to break larger, more complex carbohydrates, lipids, and proteins into smaller molecules so they may be more readily absorbed abd used by the body.
What organ in the digestive system is responsible For nutrient absorption?
The small intestine is responsible for the absorption of nutrients.
What are the main ingredients of indigestion tablets?
Indigestion tablets (antacids) may contain: CaCO3, MgCO3, Al(OH)3, Mg(OH)2, NaHCO3, KHCO3, etc.
All these substances dissolved make an alkaline solution - to neutralize the excess of hydrochloric acid from the stomach and to control of the gastric pH.
What the order in which food passes threw the digestive system of a bird?
After food enters the mouth, it moves through the throat, esophagus, stomach, the small intestine that consists of three segments called the duodenum, jejunum, and ileum, and finally the large intestine. The large intestine extends from the cecum to the rectum, where waste is stored. This waste is excreted through the anal canal.
The histology changes in each segment of the GI tract, but from the esophagus to anus it has four main layers that vary according to location. They are called the mucosa, the submucosa, muscularis, and serous layers. The real difference is in the small intestine which contains plicae circulares covered with villi and microvilli for absorption of nutrients.
What can you eat that doesn't cause indigestion?
Yogurt
Another answer:
That depends on the cause of indigestion. If the problem is inability to digest milk products, then one needs to avoid dairy, including yogurt. In general, mild, bland foods without much fat, oils or spices are recommended for those having indigestion, but it is best to consult a medical professional to determine the cause.
