How long is doudenum?
10 - 15 inches long
Where does Bile it act in the digestive system?
The bile from the bile duct is sent to the pancrease and is then secreted unto the food, or at this point chime, in the doudenum.
What is the function of doudenum?
The main function of the duodenum is to break down the food when it enters the small intestine. It uses enzymes to assist with the breakdown of the food.
Which organ in the body responsible for the storage of bile?
The gallbladder is the sac-like structure under the liver that stores about 30-50 ml of bile. The liver produces bile, and the gallbladder stores it. From there it is excreted, travels down the bile duct, where it passes through the pancreas, which produces lipase (which does break down fat), before it goes into your small intestine. The gallbladder releases bile into the duodenum, part of the small intestine, to aid in the digestion of fats. Bile emulsifies the fats, or breaks them into smaller particles, to assist in their digestion. If the bile salts crystallize, you get gallstones.The gallbladder will release bile only under the influence of cholecystokinin. When the chyme (food leaving the stomach after processing) passes through the plyoric sphincter (valve muscle connecting the doudenum to the pylorus (bottom part of stomach), this hormone is released, and the bile is released into the doudenum through a series of ducts that also lead from the pancreas, so the enzymes for further digestion can enter as well.Common Bile Ductsmall intestineAlthough the gallbladder does not make the bile, it is where the bile is stored.The gallbladder stores bile in the body until it is needed in the digestive process. When spicy or fatty foods are eaten, the gallbladder will release the bile into the stomach to help with the digestion.
What happens if there's a blockage in the gallbladder?
A blockage of the tube leading out of your gallbladder is called the cystic duct and joins with another tube leading out of your liver (called the common hepatic duct) to create the common bile duct. A blockage in the cystic duct will give you biliary colic, wave like pain starting under your right ribs and spreading across to your left especially when you eat fatty foods. If this gets infected, you will get cholecystitis with fever, pain, chills and shakes. If you get a blockage in the common bile duct, you will get fever, pain, chills and shakes plus you will become jaundiced (yellow).
How do carbohydrates reach cells?
In relatively simple terms. Carbohydrates are broken down by a certain protein called amalyse, which is an enzyme. These enzymes are secreted through glands in under the tongue and sent from the pancreas into the stomach. Most of this digestion takes place in the stomach. The carbohydrates are then broken into smaller molecules called monosaccharides and polysaccharides. Examples of each are glucose (monosaccharide) and maltose (polysaccharide). I'll use glucose as the example. When carbohydrate breaks down into glucose it is a lot smaller. These small particles travel down the small intestine. Some larger particles are broken down further at the duodenum. When glucose reaches the illeum microscopic villi absorb the glucose into the blood stream. It is the blood (more so the plasma in the blood) the carries the glucose to the desired cells, where it can be used for energy during respiration. But in all technicality carbohydrates never get any further than the doudenum! They are too big to be absorbed by cells in any animal!
What are the steps to the pigs digestive systems?
1.) Food enters the oral cavity 2.) Passes through pharynx 3.) Enters esophagus via glottis 4.) Involuntary wave of smooth muscular contractions (peristalsis) moves food down esophagus to cardiac stomach (food broken down by muscular contractions and gastric juices...hydrochloric acid and pepsin) 5.) pyloric stomach 6. small intestine via pyloric sphincter -duodenum: digested food mixes with enzyme secreted by intestinal epithelium, bile form gallbladder, and enzymes of pancreas -jejunum: chemical digestion and nutrient absorption takes place -ileum 7.) enter large intestine via muscular sphincter caecum: fermentation reservoir where cellulose is digested -colon: -descending colon -rectum *water reabsorbed form wastes of digestive tract, feces becomes more solid 8.) fecal matter expelled through anus

If you eat a cracker made of carbohydrates how is it digested by beginning with the mouth and ending with the liver?
Liver?From mouth to the liver? The liver?!Although the liver is an important organ in the digestion process, food doesn't end up there or even pass through it.Having said that, I'll start this off:The digestion process starts in the mouth with the chewing of food, which increases its surface area. Also, starches, like the ones found in a saltine cracker, are broken down by saliva, which turns starch into simple sugars. From the mouth it passes to the stomach.Next!Part 2The stomach contains hydrochloric acid acid and lots of enzymes, which, together with a squelching action of the stomach breaks the last of the cracker down into it's absorbable chemical constituents. None of the cracker's actually absorbed here however. After 1/2 to 1 hour the slimy acidic paste passes into the small intestines where the clever stuff begins.Next!The liver producesm bile, which emulsifies fat to prepare it for digestion by pancreatic and intestinal juices.
