What is the name For the muscular contractions that move food though the alimentary canal?
PERISTALSIS
Partially digested food in stomach?
the food will digest in the small intestine by the stomsch and eshopagus
What is 3 things food is used for in your body after it is broken down?
1. Fats 2. Carbohydrates 3. Proteins
What is the appndix's function?
Conventional medicine has long thought the appendicitis to be of no function what-so-ever, but recent discoveries have found that the appendicitis regulates hormone and energy balance as well.
From what i can gather, the digestive system provides the circulatory system with all the nutrients the blood and body need. The digestive system provides the body with energy from food and that energy feeds the muscles surrounding the heart.
Actually, *every* person expels numerous small non-odorous pockets of air every single day, all day long. These are just not strong enough to be felt or make sounds, nor contain much methane. Some people may feel a small expulsion as if the anus has puffed, but there is no odor or sound.
What carried food from the throat to the stomic?
The esophagus carries food from the mouth to the stomach.
Is it true that chewing is the first step of digestion?
No, actually thinking about the food is the first step because you start to salivate when you see or think about food.
What are the names of the three phases of the digestive system?
The three phases of the digestive system are the oral phase, the gastric phase and the intestinal phase. All together, they help you break down large food pieces into progressively smaller units that can undergo absorption and nourish the cells and tissues of your body.
Which is the correct order of the large intestine segments?
The cecum and the ancending,transverse,descending, and sigmoid colons
How does bile help the digestion of milk?
Bile emulsifies the fat so it can be broken down further by pancreatic lipase. The resulting tiny droplets are then absorbed by the lacteals in the intestinal villi and carried throughout the body by the lymphatic system.
What things will keep the digestive system and small intestine working properly?
by drinking as many fluids as possible
If the third stage of digestion is absorption which begins when food enters the?
The jejunum or ileum of the small intestine.
How does your mouth start the digestive process?
The start of the process - the mouth: The digestive process begins in the mouth. Food is partly broken down by the process of chewing and by the chemical action of salivary enzymes (these enzymes are produced by the salivary glands and break down starches into smaller molecules).
On the way to the stomach: the esophagus - After being chewed and swallowed, the food enters the esophagus. The esophagus is a long tube that runs from the mouth to the stomach. It uses rhythmic, wave-like muscle movements (called peristalsis) to force food from the throat into the stomach. This muscle movement gives us the ability to eat or drink even when we're upside-down.
In the stomach - The stomach is a large, sack-like organ that churns the food and bathes it in a very strong acid (gastric acid). Food in the stomach that is partly digested and mixed with stomach acids is called chyme.
In the small intestine - After being in the stomach, food enters the duodenum, the first part of the small intestine. It then enters the jejunum and then the ileum (the final part of the small intestine). In the small intestine, bile (produced in the liver and stored in the gall bladder), pancreatic enzymes, and other digestive enzymes produced by the inner wall of the small intestine help in the breakdown of food.
In the large intestine - After passing through the small intestine, food passes into the large intestine. In the large intestine, some of the water and electrolytes (chemicals like sodium) are removed from the food. Many microbes (bacteria like Bacteroides, Lactobacillus acidophilus, Escherichia coli, and Klebsiella) in the large intestine help in the digestion process. The first part of the large intestine is called the cecum (the appendix is connected to the cecum). Food then travels upward in the ascending colon. The food travels across the abdomen in the transverse colon, goes back down the other side of the body in the descending colon, and then through the sigmoid colon.
The end of the process - Solid waste is then stored in the rectum until it is excreted via the anus.
What is the role of villi in the alimentary canal?
The role of the villi in the alimentary canal is to allow for a greater surface area in which the absorption of nutrients can take place.
Part of the digestive system are parietal cells located?
Parietal cells are found in the fundic zone of the stomach.
Takes in dissolved food.
Villi means "finger" and is typically used to describe the surface of the small intestine, which is covered in millions of tiny finger-like projection which aid in absorption of nutrients from food.
What is the function of the Protease in digestion?
Protease is a enzyme designed to break down proteins, and this is just what it's used for in the body.
An example being the chemical digestion of food-protein.
I.e.: If you eat protein-containing food, like meat, the enzyme protease will cut the proteins of the meat into aminoacids (the buildingblocks of protein) which can then be absorped through the gastrointestinal wall and into the blood-stream.
Once in the blood-stream the aminoacids can be used for a variety purposes, including build-up of muscle-tissue.
What are three common digestive problems in elderly people?
Gall bladder control, something else and that's all i know.....
What begins mechanical breakdown of food through mastication?
The mechanical breakdown of food starts with the saliva in your mouth.
