If you eat a cracker made of carbohydrates how is it digested by beginning with the mouth and ending with the liver?

Answer 1

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 2

The 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.

Answer 2

Answer

The first part of the digestive process in the mouth is initiated by the salivary glands which secrete a chemical called salivary amylase. This enzyme begins the digestion of the starches in the cracker into simple sugars. Then when it gets into the stomach it is called chyme and doesn't get digested further because the stomach only digests proteins. After it's been in the stomach for several hours, it goes into the duodenum, the first part of the small intestine, and this is where the pancreas adds pancreatic amylase, another enzyme, to help break down the starches from the cracker even further.

As far as the liver, it does not play a role in digestion directly. It's job is to convert the sugar, or glucose, into glycogen, which is a stored version of the sugar that came from the starches, or carbohydrates, that were originally in the cracker.

Answer

The liver also produces bile which flows into the doudenum for the digestion of any lipids in the cracker.

The liver is also involved breaking down glycogen from adipose tissue or muscle to glucose when your body is in fasting mode. Besides this, the liver also produces urea from protein, which is then excreted as urine.

Answer 3

Amylase in the saliva starts the process of breaking down starch into sugar. The mouth also physically breaks down the cracker. The stomach and intestines continue to break down the complex carbohydrates in the cracker into simpler carbohydrates, and finally sugar. The sugars are absorbed through the intestines. Sugars not immediately used by the body get stored in the liver as glycogen, a complex carbohydrate. When the body needs to draw on reserves of fuel, it goes first to the liver and breaks down the carbohydrates there into sugar (glucose) so the body can use the energy.

Answer 4

The process of digesting carbohydrates begins in the mouth. Salivary amylase starts breaking down complex carbs into simpler types. Enzyme activity continues in the stomach, but salivary amylase is neutralized in the stomach.

Pancreatic amylase is secreted into the duodenum. This reduces the carbohydrates into simple sugars - maltose, lactose and sucrose. The enzymes maltase, lactase and sucrase digest maltose, lactose and sucrose, which are more easily absorbed. They re eventually converted to glucose and absorbed through the intestinal walls into the bloodstream. After carbohydrates are made into glucose, the glucose is absorbed into the bloodstream and taken to the liver, where it is stored or distributed to cells throughout the body for energy. The liver is responsible for regulating blood glucose levels. the liver converts excess glucose to glycogen and stores it; it also converts glycogen to glucose when the levels int he body are low.
