What type of digestive system does an insect have?
Arthropods are the most complex classification of animal in the ocean there not bugs they consist of eye appendages exoskeletons claws jointed limbs and thumb like appendages
some examples are lobster and crabs.
Id like to point off, that had absolutely nothing to do with the digestive system, which is what the original question had asked. They have an extra-cellular digestive system, this means it takes place outside the body.
your wrong, it does have something to do with the digestive tract, they have a gastrovascular cavity.
Where does the body prepare digestive wastes for elimination?
Body waste isn't stored. It's excreted through the skin (sweat), the breath and out of your body in pee and poo. Yum.
What does the inside of the small intestines look like in a fetal pig?
The small intestine of a pig is a major site of nutrient absorption. The pancreas releases digestive enzymes into the small intestine, which break down nutrients from food. The nutrients are absorbed in the last section of the small intestine, and whatever is left passes to the large intestine.
What are the end products of the digestion of starch proteins and fats?
Nutrients in the body and feaces.
What is the organ that produces bile and detoxifies a variety of substance?
liver
That sounds like jobs for the liver.
The Liver
no Its probably just as sign of u ovulating or normal period painsif u do not get your period then imediatley take pregnancy test though Unlikely. All of the symptoms you described occur before a period is going to arrive. But if your period doesnt arrive, do a pregnancy test. Could be implantation.. or not.. I would take a test in four days... Sorry for the short answer but a test is the only way to know for sure you are pregnant.. that or go get a blood test from your doctor. :) GL

How does your rectum break down food?
The rectum doesn't do anything to break down food. By the time "food" reaches the large intestine, what was at one time "food" is then liquefied waste. In the small intestines, fluid is added. So in the large intestines, the fluid is pulled back out of the waste and then pushed toward the kidneys to process it. As the fluid is pulled back, the liquefied wastes become semi-solid (to very dry solid if constipated). After going through the last part of the large intestines, the solid waste (stool, feces) is pushed into the top of the rectum. The rectum acts as a holding receptacle and as a nerve center that sets off a "gotta go" signal through a feeling of fullness, e.g. pressure on the nerves in the walls of the rectum. The rectum is about 10-12cm in length. So it can hold a lot of waste. Also, because the intestines and rectum are basically round tubes, resulting in us having a mostly rounded stool (unless we end up with too much water left in the waste, resulting in diarrhea. As you can see, the rectum has nothing to do with breaking down food.
When you eat an apple the process of digestion involves?
The digestion starts when the teeth to bite into the apple. This begins to break down the apple by dividing it into bite sized pieces. Then the teeth and jaws chew the apple to break the bite sized pieces into smaller pieces. This is to make the apple pieces small enough to fit through the oesophagus and to make less work for the stomach. While the apple is still in the mouth, the saliva contains an enzyme which starts it off by making the food softer, thinner and smaller by slowly eating away at it.
The Oesophagus:
The apple is then swallowed which takes the food from the mouth to the oesophagus. The apple then moves through the oesophagus.
The Stomach:
After food has left the oesophagus it enters the stomach. This is where chemical and enzymatic digestion starts. In there, there are acids that dissolve food down into smaller pieces. As food is liquefied in the stomach, it is slowly released into the small intestine.
The Small Intestine:
The small intestine sucks up all of the nutrients in the apple before sending the nutrients to the veins that are carried through the body by blood.
The Liver:
The liver has hundreds of functions. One of its main functions is to process fat and other nutrient-rich liquefied food that drains from the small intestine so it can be used. Another important function of the liver is that it produces sugars from proteins and fatty substances; and it secretes albumin which helps to keep fluid within the blood vessels.
The liver also converts poisons in the blood into materials which can be safely excreted from the body. The liver uses calcium to reduce the amount of acid in the body waste. This allows us to go to the bathroom without pain or body damage.
It also secretes bile which is a substance containing fatty materials. These help in the digestion, as well as the absorption of fatty products.
The Gall Bladder:
The gall bladder is a pouch-shaped organ which lies near the liver. It accepts bile from the liver, and stores it. When food is digested, the gallbladder releases bile into the small intestine where it is able to help dissolve fats.
The Pancreas:
The pancreas makes and delivers digestive juices through a tube called the pancreatic duct to the upper part of the small intestine.
The Large Intestine:
The parts of the food that can't be digested get pushed into the large intestine, also called the colon. It is about 5 feet long. Its function is to move the waste from the small intestine on to the rectum. The material first passes through the ascending colon and then through the transverse colon. Throughout this process, it absorbs more water. By the time the waste reaches the segment called the sigmoid, it is quite firm. The sigmoid colon is designed to slow down this movement of the waste until it is ready to be eliminated.
The lowermost segment of the large intestine is called the rectum. It stores the firm waste until you are ready to get rid of it by "going to the bathroom". It has a specialized muscle, called the anal sphincter, which prevents the body waste from escaping until the appropriate time.
Can the stomach lining repair its self?
Yes stomach lining can be thrown up when the stomach is empty thus it will be the only thing left for your body to rid itself of. It has happened to me a few times and it is quite painful sometimes, usually it is a cloudy yellowish-greenish.
What is the process that causes food to move through the digestive tube?
There is a process of involuntary contraction and relaxation in successive waves within the the walls of the esophagus and intestine that forces the food along.
This process is called Peristalsis.
Does digestion begin in your stomach?
Correctly, physical digestion begins in the mouth, when foodstuffs are pulverised and mashed up into small pieces, and coated with saliva, to make swallowing easier and to increase it's surface area. This process is completed in the stomach, where food is liquified by strong hydrochloric acid secreted by the gastric glands to make it easy to assimilate. All these processes are classed as physical digestion, but not actual ABSORPTION- this takes place in the small intestines. The only substance absorbed by the stomach is alcohol.
What are the sites and enzymes that digest protein in the body?
The first stages of digestion for protein occur in the stomach, here the enzyme pepsin breaks down the majority of the protein into separate amino acid molecules. The next stage is in the duodenum of the small intestine.
What are the parts of the digestive tract or gut?
In order:
- mouth
- pharynx
- esophagus
- stomach
- small intestine
- large intestine
- rectum
In a mammal, the food passes through a canal called the alimentary canal. The process of digestion begins in the mouth. From the mouth, it moves to the pharynx, down to the esophagus, and into the stomach.
Here, it'll stay as long as it is necessary, then it will move down to the first part of the small intestine, the duodenum.
This is where many enzymes are secreted by the pancreas and gets broken down. It then moves down to the other two parts of the small intestine, jejunum and ileum (in that order). Here, the enzymes will continue to break macromolecules down, while villi will take nutrients out for your body to use.
This "soup" of mostly digested food is then taken to the large intestine, where most of its water will be taken out. As it moves through three parts of large intestine, ascending colon, transverse colon, descending colon, and finally to the sigmoid colon, water is taken out so that you won't have diarrhea all the time. The remaining substance is dumped out through your anus.
What are three easy questions and answers about the excretory system?
question:what is the large intestine
answer:your large intestine removes water from the undigested material.
question:what is the small intestine
answer:here,digestive juices from your liver and pancreas finish digesting the food.
question:meaning of pancreas
answer:your pancreas makes other kinds of digestive juices.they pass through a tube into your small intestine.
proof its right : i found it on my old science saurus ( a human handbook)
Digesting food is involuntary?
Digestion is an involuntary process. You do not control digestion, it just happens.
Why does indigestion medicine contains Citric Acid?
Citric acid is a mild acid, and sodium bicarbonate is a mild base. When you combine the two in H2O, the acid reacts with the bicarbonate releasing carbon dioxide gas (and I think forming sodium citrate) and neutralizes the solution. This gas is the "fizz-fizz" that follows the "plop-plop" in the Alka-Seltzer ad, and it is the reason why it is called Alka- SELTZER. I'm not a chemist, but I suspect the sodium citrate is a harmless byproduct rather than a useful medicine. Sodium citrate is mostly used as a chelate or antioxydant in prepared foods and medications.
By the way, the active ingredient in this formulation is 325 mg aspirin. I'm not sure how aspirin helps indigestion since it irritates a lot of people's stomachs. But I think the idea behind the acid/base reaction is to have some of that fizz enter the stomach where it will become trapped eventually causing you to belch.
The inside of the digestive system is lined up with what tissue?
OOH OOH, MS CLIFTON, MS CLIFTON! Is it Mucus?
== == Lactose is a disaccharide sugar; a sugar composed of two monosaccharides. the two momosaccharides that make lactose are glucose and galactose. the enzyme lactase splits these two monosaccharides appart and they are easily digested. glucose can go directly into cells to be used as energy but galactose must be converted into glucose by the liver first.
Lactose is digested by the liver and converted into energy and waste, just as is most other things you ingest. It gives energy to the creb's cycle, which is a major energy provider in the body. (However lactose doesn't provide very much energy at all)
