The digestive system is a group of organs that work together in order to convert food into energy and basic nutrients that are needed to feed the entire body. There are six main functions of the digestive system, these are:
1. Ingestion of food
2. Secretion of digestive enzymes and fluids
3. Movement and mixing of food and wastes through the body
4. Digestion of food into smaller pieces
5. Absorption of nutrients
6. Excretion of wastes
Indigestion can sometimes be known as the intake of food. The mouth is responsible for this function, as this is where all food enters the body. The mouth and stomach are also responsible for the storage of food as it waits to be digested. Throughout the course of the day the digestive system secretes

The ileums main function in to absorb the vitamin B12, bile salts and whatever products of digestion the jejunum didn’t absorb. The walls on the ileum are made up of folds, each of these folds has many villi on its surface. This helps to increase the surface area allowing more absorption to happen.
Large intestine – the main function of the large intestine is to absorb water from any remaining indigestible food matter and transmit the useless waste material from the body. Vitamin k and b are secreted by ‘good’ bacteria.
Rectum – the rectum is the final part of the large intestine that concludes in the anus. The average length of a human rectum can range between 10cm and 15cm. Primarily the function of the rectum is to act as a temporary storage site for stool before it is eliminated from the body.
Anus – the anus is the last part of the digestive tract. It is a 2-inch long canal consisting of the pelvic floor muscles and the two anal sphincters (internal and external). The upper anus has a specialized lining to detect rectal contents. It lets you know whether the contents are liquid, gas or
The seats hold the crowd in place during the game. 8. Lysosomes - Lysosomes help the digestive process. They contain enzymes that speed up the process and help digestion of food and other materials. Lysosomes are like mitts in baseball.
The proper functioning of one system relies on the proper functioning of the other system. In other words, the digestive system needs to be in good working order to support the functions of the cardiovascular system. An example of the digestive and cardiovascular systems interrelating is: the first step in digestion of fat is to dissolve it into the intestine where bile acids produced by the liver dissolve the fat into fatty acids and cholesterol. The bile acids join with the fatty acids and cholesterol and vessels then carry the changed fat to the veins of the chest, and the blood carries the fat to storage in different parts of the body.
Crohn's Disease Crohn’s Disease is a disease that causes inflammation in the small intestine. Millions of people all over the worldwide are suffering from Crohn’s Diseases. In 1932, Crohn’s Diseases was referred to as a medical illness and it was described by Dr. Crohn, Dr. Leon Ginzburg, and Dr. Gordon Oppenheimer. But it all started in 1913 by a physician named Kennedy Dalziel who had a meeting with the British Medical Association, and described his nine cases with patients who suffered from intestinal obstruction. One day with a close examination of the inflamed bowel of a patient, the transmural inflammation that is characteristic of the disease was clearly evident.
The yeast menace is known by several different terms, candidosis, yeast infection,monilia and thrush. Symptoms of yeast infections are vast, however there are some that are more obvious, these include chronic tiredness, cystitis and thrush that continues to come back even after you have treated it. Some other symptoms which are not as obvious include, anxiety,mood swings, fluid retention ,allergies,depression,inability to loose weight,constipation, diahorrea, PMS, acne and dermatitis as well as hypoglycaemia. With a list as exhaustive as this, it's easy to see why it's deemed one of the most debilitating immune deficiencies and nutritional disorders of our time, As with any infection, one or many of the symptoms may exist, however, advanced
Ileostomy Surgery Ileostomy surgery redirects part of the small intestine (ileum) to an external opening (stoma) in the abdomen. This means that waste is passed through the stoma, instead of passing through the rest of the intestines and the rectum (bowel). The stoma may have a valve and a tube (catheter) to pass waste, and there may be an external pouch (ostomy pouch) attached to the stoma to collect waste. This procedure may be necessary when the bowel is diseased or partially removed. It can be temporary or permanent, and there are several types of ileostomy surgery.
The main body is broken into three sections. There is the abdomen, thorax,
The digestion tract for earthworms is much like the crayfish. Food enters the mouth and gets pushed down into the esophagus by the pharynx. Next in line is the crop; an organ very similar the cardiac stomach. In the crop food in held until it is moved into
The digestive system is responsible for chemically and mechanically breaking down food and includes organs such as, mouth, esophagus, stomach, small intestine, rectum, anus, and additional accessory organs. These organs all aid in the breakdown of food. Food is broken down mechanically by chewing and churning in the stomach, and chemically by acidic enzymes in the stomach and in the small intestine which receives enzymes from the pancreas that are specifically designed for the breakdown of nutrients. Once the food and nutrients are broken down, the excretory system removes whatever the body decides is waste by filtering blood in the nephrons of the kidneys and turning it into urine which is then collected in the bladder and removed from the body when the bladder is
The Digestive System The digestive system is a system consisting of the mouth, oesophagus, stomach, gallbladder, small intestine, large intestine, the rectum and the anus. The functions of the digestive system are: • To break down food particles into molecules for digestion • To absorb into the bloodstream the small molecules produced by digestion • To eliminate un digested and unabsorbed foodstuffs and other waste products from the body The full digestive process begins at the mouth. The food enters the mouth and is chewed.
CLAIRE MUNTING 29/01/2018 Criterion C EFFECTS OF SURFACE AREA OF CALCIUM CARBONATE UPON RATE OF REACTION Calcium Carbonate Chips 1 Introduction: Within the current investigation, the effects of the surface area of Calcium Carbonate (CaCO3) in combination with Hydrochloric acid (HCl) upon its rate of reaction. CaCO3, commonly referred to as limestone, is an organic substance and is, in a sense, the crystallised “carbonic salt” of the element, calcium2. In addition to being a salt, the pH level of Calcium Carbonate is 9.91, and it is therefore, a basic substance, due to the fact that it is comprised of a pH level higher than 7, which is neutral3. HCl, however, is the bodily acid found in the stomach of human beings.
At least 70 million people in the U.S. suffer from some sort of digestive illness (not including heartburn), and digestive problems account for nearly 10% of all healthcare spending. The hard-working gut allows nutrients and water to enter the body while preventing the entry of toxins/antigens. It’s a selective barrier between “us” and the outside world. But a distressed gut can’t act in our defense.
Introduction Gallbladder is an organ in the body and it is part of the biliary system. It is a pear-shaped muscular sac that is located on the ventral surface of the liver and on the right side of the abdomen. Moreover, it has 3 layers; an outer serous peritoneal layer, a middle smooth muscle layer and the last layer is an inner mucosal layer which is connected to the lining of the bile duct. The main function of the gallbladder is to store and concentrate bile which helps the body to break down and digest fats.
The endocrine system is such an important system to the body because it functions the bodies use of hormones. The body uses many different hormones and the endocrine system regulates these. When the glands of the endocrine system secrete the hormones, the hormones are put into the bloodstream to be sent to the different parts of the body. The glands that comprise the endocrine system are the hypothalamus, the pituitary gland, and the pineal gland which are all located in the brain, the thyroid, parathyroid, and thymus which are located in the throat, the adrenals and pancreas which are located in the body’s midsection, and the ovaries (female) and testes (male) which are located in the pelvic region. The system is so important because it regulates the body’s metabolism, growth and sexual development, digestion, heart rate, and many of the other body functions regulated by hormones.
The digestive system is located around the stomach area. Along with the digestive system, many other organ systems all work together to create an organism. An example of this would be if a person eats a sandwich and then goes for a run. During the run, the circulatory system helps the body breathe, the muscle system helps the bones move, and all the while the digestive system digests the food. Later on, the excretory system gets rid of the waste, or food that the body can’t use for nourishment.
The nerve supply also comes from her celiac plexus innervating the liver mixture of sympathetic and parasympathetic fibers. These ribs reach the liver by the hepatic artery. Liver Physiology The liver performs many functions in the body such as: • Production of bile: The liver excretes bile to the bile duct and thence to the duodenum. Bile is necessary for digestion of food.
