what is the function of the liver, Gullet, small intestines, big intestines, rectum and mouth
Answers
Answer:
The liver regulates most chemical levels in the blood and excretes a product called bile. This helps carry away waste products from the live.
The oesophagus (gullet) is part of the digestive system, which is sometimes called the gastro-intestinal tract (GI tract). The oesophagus is a muscular tube. It connects your mouth to your stomach. When you swallow food, the walls of the oesophagus squeeze together.
The small intestine carries out most of the digestive process, absorbing almost all of the nutrients you get from foods into your bloodstream. The walls of the small intestine make digestive juices, or enzymes, that work together with enzymes from the liver and pancreas to do this.
The large intestine is much broader than the small intestine and takes a much straighter path through your belly, or abdomen. The purpose of the large intestine is to absorb water and salts from the material that has not been digested as food, and get rid of any waste products left over.
The rectum is a straight, 8-inch chamber that connects the colon to the anus. The rectum's job is to receive stool from the colon, let you know that there is stool to be evacuated (pooped out) and to hold the stool until evacuation happen.
The two main functions of the mouth are eating and speaking. The face's trigeminal nerve provides sensation (feeling) and helps us to bite, chew and swallow. Some disorders of the mouth include infections, ulcers, cancer, cleft palate, dry mouth syndrome, dental caries and speech problems such as lisping

Temporary magnets are usually made of iron, cobalt, or nickel. These materials behave like magnets only when they are near a strong magnet.A narrative is an oral or written account of an event, experience or incident in a person’s life, presented to a reader or listener in a sequence of written or spoken words. Often the word narrative is synonymous with story. A narrative can be fiction or non-fiction. Sometimes there is a narrator, a character or series of characters who tell the story. Sometimes, as with most non-fiction, the author himself/ herself is the narrator. You are narrators of your own lives all the time. Narrative writing is very important in our day-to-day life. It tells others the stories of our personal experiences and allows us to gain empathy and sympathy from the world around us.At least 8 colleges across Bengal have suffered on account of an alleged cyber prank that saw their admission merit lists manipulated to reflect names of famous personalitiesthe great increMagnets that retain their magnetic
The food you eat takes an incredible journey through your body -- from top (your mouth) to bottom (your anus). Along the way the beneficial parts of your food are absorbed, giving you energy and nutrients. Here’s a step-by-step account of the digestive system’s workings.
Your digestive system is uniquely constructed to do its job of turning your food into the nutrients and energy you need to survive. And when it’s done with that, it handily packages your solid waste, or stool, for disposal when you have a bowel movement.
The main organs that make up the digestive system (in order of their function) are the mouth, esophagus, stomach, small intestine, large intestine, rectum and anus. Helping them along the way are the pancreas, gall bladder and liver.
Here’s how these organs work together in your digestive system.
.Mouth
The mouth is the beginning of the digestive tract. In fact, digestion starts before you even take a bite. Your salivary glands get active as you see and smell that pasta dish or warm bread. After you start eating, you chew your food into pieces that are more easily digested. Your saliva mixes with the food to begin to break it down into a form your body can absorb and use. When you swallow, your tongue passes the food into your throat and into your esophagus.
Esophagus
Located in your throat near your trachea (windpipe), the esophagus receives food from your mouth when you swallow. The epiglottis is a small flap that folds over your windpipe as you swallow to prevent you from choking (when food goes into your windpipe). A series of muscular contractions within the esophagus called peristalsis delivers food to your stomach.
But first a ring-like muscle at the bottom of your esophagus, called the lower esophageal sphincter, has to relax to let the food in. The sphincter then contracts and prevents the contents of the stomach from flowing back into the esophagus. (When it doesn’t and these contents flow back into the esophagus, you may experience acid reflux or heartburn.)
Stomach
The stomach is a hollow organ, or "container," that holds food while it is being mixed with stomach enzymes. These enzymes continue the process of breaking down food into a usable form. Cells in the lining of the stomach secrete a strong acid and powerful enzymes that are responsible for the breakdown process. When the contents of the stomach are processed enough, they’re released into the small intestine.
