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...

Where are carbs digested?

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.

Why is your anus bleeding?

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'

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?

How does digested food get into our 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

What is the term meaning surgical removal of the appendix?

Appendectomy. "Ectomy" being a suffix that originates in Greek and used in medical terminology as "surgical removal of..." Literally meaning "a cutting out of", "to cut out", or "to cut". Appendectomy is the American expression. The English and Australian expression is appendicectomy (although the Australian usage is tending towards the American one).
Appendicectomy
Appendectomy

What happens to the starch in your mouth?

It is broken down into glucose molecules, which are then transported to cells to be used as an energy source or stored as glycogen.

Is the Larynx part of the digestive system?

The larynx (voice box) is part of the respiratory system that holds the vocal cords. It is responsible for producing voice, helping us swallow and breathe. Air passes in and out of the larynx each time the body inhales or exhales. Air from the lungs passes over the stretched vocal cords, and the vibrations are modified by the tongue, palate, and lips to produce speech.

What is the length of the small intestine of a mouse?

A dog's intestine depends on the dog's size. The small intestines are approximately two and a half times the size of a dog.

Why is it necessary for the food to be broken down into its simplest form?

It is on its way to being made into enzymes. They are made of the broken down food molecules. That is about as small as things get.

Where does saliva digest?

Saliva digests carbohydrate. Saliva contains a carbohydrase enzyme called amylase, which breaks down carbohydrates. Amylase is also produced later on in the digestive system and so the amylase here is immaginatively termed salivary amylase.
Saliva contains the enzyme amylase (here it is called called salivary amylase) which is responsible for part of the digestion of carbohydrates like starch.

Does any digestion of food occur in the esophagus?

Yes saliva is used to help turn the food into a substance which is able to slide down the esophagus. Salivary glands produce the saliva in the mouth however; the saliva does help to digest the food slightly in order for it to be moved by peristaltic waves. The main function of the esophagus is to move the food, but it will have been slightly digested.

The esophagus leads into the stomach.?

Things transfer from your esophagus to your stomach through the cardiac sphincter

Name the food component that is digested in the stomach?

The stomach is located between the esophagus and the small intestine. It secretes protein-digesting enzymes and strong acids to aid in food digestion, (sent to it via oesophageal peristalsis) through smooth muscular contortions (called segmentation) before sending partially digested food (chyme) to the small intestines.

What parts of the body do you use to bring in and digest food?

Your digestion body parts relates to your esophagus. Which is basically the inside part of your neck that foods and drinks go down. Then your food goes through the reproductive system to get its food churned up. Then when your food hits the bottom that is digestion. After that the digestion is basically telling you that you need to go to the bathroom. You basically poop it out. then once it lands into the toilet you flush the toilet then it goes to the sewer then into the ocean then we get water from the ocean and clean it and it becomes drinking water that you basically drink every day.

What are the major organs of the digestive system and what does each do?

Mouth and associated structures - physical disruption of food, entry point

Stomach - breaks stuff up with physical force, acid etc

Small/large intestines - absorption of nutrients

What type of tissue works to move food along the digestive tract?

Peristalsisis a radially symmetrical contraction and relaxation of muscles which propagates in a wave down the muscular tube, in an anterograde fashion. In humans, peristalsis is found in the contraction of smooth muscles to propel contents through the digestive tract. Earthworms use a similar mechanism to drive their locomotion.[1] The word is derived from New Latin and comes from the Greek peristallein, "to wrap around," from peri-, "around" +stallein, "to place".

How the circulatory system work without the digestive system?

The Circulatory System works with the Digstive System in several ways. One of them being that the digestive system breaks down food to get the nutrients, where it is then sent to the ileum (small intestine) to be absorbed by the villi that cover the walls of the ileum. In the villi there is a capillary that absorbs the nutrients into the lood stream and the blood then distributes these nutrients (or energy) around the body because of the pumping action of the heart. Hope this helps a bit :)

What is the difference between the human digestive system and a pigs digestive system?

There are many differences between humans and cows. But the most notable difference is the digestive system. Cows have a digestive system that enables them to eat and digest plant matter (fibre, cellulose, hemicellulose, starches, etc.) more efficiently than humans. It is this difference that makes cows able to eat roughage and coarser forages than what humans are able to chew through. Humans, on the other hand, are more able to digest animal proteins more efficiently than cows. Essentially, cows are herbivores and humans are omnivores by natural selection and evolution.

Cows are ruminants, which means they have one large stomach with four compartments that enable coarse plant matter to be digested and broken down in four steps, starting in the reticulum, which collects hardware and other things that cannot be digested or passed through the animal, followed by the rumen, which is a fermentation vat that breaks down fibrous material with the work done by microflora. The omasum absorbs the excess "water" from the digested material, and then further digested by the abomasum, with enzymes to digest proteins and starches.

Humans are monogastrics, which only have one stomach with one compartment. Enzymes or peptides are designed to help break down proteins and starches, but not fibre or cellulose. Proteins stay in the stomach longer because they are being broken down more efficiently. Plant matter passes through more quickly because it can't be digested as efficiently. The only real benefit with fibrous matter is that it helps with healthy bowel movements.

Cattle also have a large functioning cecum that is used to further break down fibre that was missed being broken down in the rumen. Humans, on the other hand, have what is supposed to be a cecum that actually has no significance to the human's digestive system: the appendix is just a useless piece of skin attached to the large intestine that does nothing except cause pain when it gets infected.

What is the alimentary tract?

Gastrointestinal tract is a pathway for entrance, passage, digestion, metabolism and excretion of food and consists of the mouth, pharynx, esophagus, stomach, intestines, colon, rectum and anus

What happens to food we don't digest?

The bits of food that can not be digested are sent to the large intestine where they are stripped from most of their water, this food, which is now Feces, is stored in the rectum until it is eradicated from the body during a bowel movement.

What is the end product of carbohydrate digestion?

The most important end product of digestion is the separation of nutrients, most of which are absorbed through the small intestine and distributed throughout the body cells by the circulatory system.
