The Pancreas is a very soft and tadpole shaped gland. Most of the pancreas is located deep to the greater curvature of the stomach. The pancreas is important to the digestive system because it produces enzymes that break down all categories of food. The Pancreas also creates a juice called pancreatic juice which drains from the pancreas into the duodenum. About 1200 to 1500 ml of clear pancreatic juice is produced daily and mostly water is consisted from it containing enzymes and electrolytes . The bulk of the pancreas is composed of exocrine which
Page 4 are cells that produces the enzymes to help with the digestion of food. The main pancreatic duct runs the length of the pancreas and drains the fluid into the duodenum which starts the first part of the small bowel. The small intestines is where the most absorption begins. It modifies digestion and absorption. The small intestines mechanically breaks down and propulsion. The Segmentation by the smooth muscle of small intestines continues to mix contents with digestive juices. When absorption begins it breaks down

Its storehouse of bacteria allows the enteric bacteria to accumulate and multiply. Even though the appendix holds a lot of bacteria it can be very dangerous if it burst because the bacteria stored in it spray over the abdominal area causing peritonitis. The large Intestines is about seven cm and is greater than the small intestines but shorter. It houses a variety of bacteria including vitamin B12, thiamin, riboflavin, biotin, various gases, and helps form vitamin K. The major function of the large intestines is to absorb most of the remaining water from indigestible foods residue, store them temporary and then to eliminate them from the body after usage.

During digestion, the body breaks down food into smaller molecules that could then be used by the body’s cells and tissues in order to perform functions. This starts off in the mouth with the physical movements of chewing and the chemical breakdown by saliva. Enzymes in the stomach break food down further after traveling from the mouth through the esophagus. The food from here then moves into the small intestine, where pancreatic juices and enzymes dissolve proteins, carbohydrates, and fibers, and bile from the liver breaks down fats into these small molecules. Any portion of the fibers or food that were unable to be broken down are passed from the small intestine to the large intestine, which is where the digestive tract transitions into the excretory tract, then the colon and out of the rectum. Any liquids that have been stripped of their nutrients by the body proceed from the stomach to the kidneys. In the kidneys, sodium ions (Na+), uric acid, and urea are exchanged with water, which moves urinary bladder and is excreted through the

The pancreas is an elongated and flattened gland located within the abdomen. Not only is it a vital part of the digestive system, but it is also a key controller of blood sugar levels. (The Pancreas). The pancreas has been divided into four regions which are the head, neck, body, and tail. Being the widest part of the pancreas, the head is twenty-three millimeters. The part of the head that hooks towards the back of the abdomen is the uncinate (Chronic Pancreatitis Imaging). Between the head and body of the pancreas is the neck, which is about nineteen millimeters. The body of the pancreas is twenty millimeters, between the neck and the tail. The tail is the smallest part of the pancreas, measuring at only fifteen millimeters. (Parts of the Pancreas). The length of the pancreas in total ranges from four point seven to seven point one inches. The pancreas also weighs from seventy to one-hundred grams (How does the Pancreas Work?).
The digestive process begins in the mouth, known as the oral cavity, where food enters. Chewing breaks the food into pieces that are more easily swallowed, while saliva mixes with food to dissolve food molecules. After that the tongue pushes food toward esophagus. The esophagus is a muscular tube extending from the pharynx to the stomach. By means of a series of contractions, called peristalsis, the esophagus delivers food to the stomach. The stomach secretes acid by tiny glands. At the same time that protein is being digested with the enzyme pepsin to break down protein into smaller molecules. Beside these muscles of the stomach contracts rhythmically to squeeze food. All the directions the food becomes thick liquid like milk shake. Then the food arrives in the small intestine from the stomach through the opening of the pyloric sphincter. The pyloric sphincter muscle is the furthest part of the stomach that connects to the small intestine. The food fully digest and absorp nutrients in small intestine with the aid of liver, gall bladder, pancreas. So the digestive system is very necessary for
The pancreas can be divided into two sections when studying the histology. The pancreas has exocrine and endocrine functions, each with unique cell types. The exocrine pancreas serves to secrete digestive enzymes into the duodenum. Some of the specific enzymes and secreted substances are Proteases, lipase, amylase, bicarbonate, and water (Bowen, “Exocrine Secretions”). These enzymes are used to break down protein, fat, and carbohydrates respectively. The bicarbonate simply act as an acid buffer to prevent damage of the small intestine as the stomach acid must be neutralized. The enzymes are created in acinar cells and the bicarbonate is synthesized in epithelial cells surrounding pancreatic ducts (Bowen “Exocrine
The pancreas is a 6-inch long organ in the body, located behind the stomach in the abdomen. The pancreas contains exocrine and endocrine glands that produce pancreatic juices, insulin, and hormones. Pancreatic juices, also called pancreatic enzymes, are made by the exocrine glands and released into the intestines to help with digestion. Around 95% of the pancreas is exocrine glands and ducts. The endocrine part of the pancreas are arranged in small clusters of cells called islets of Langerhans. Islets of Langerhans release insulin and glucagon into the bloodstream and those two hormones manage the level of sugar in the blood. When these two hormones are not working like they are supposed to, it often results in diabetes.
Large Intestine- The large intestine is made of 3 parts; the cecum, the colon, and the rectum. Some refer to the large intestine as the colon, because the colon contains four separate parts; the ascending colon, the transverse colon, the descending colon, and the sigmoid colon (WebMD (2).) The cecum connects the small and the large intestine, acting as a transition area for food to travel. The ascending colon takes feces from the cecum to the transverse colon, during this process, bacteria digest fecal matter for the release of vitamins. The longest part of the colon, the transverse colon, is where the most absorption within the large intestine takes place. The descending colon transports feces from the transverse colon to the sigmoid colon. The descending colon walls also absorb water, nutrients, and vitamins from the feces, and can store the feces until it is read to be eliminated. The sigmoid colon can also
...ve eaten, to break down the food into a liquid mixture and to slowly empty that liquid mixture into the small intestine. Once the bolus has entered your stomach it begins to be broken down with the help of the strong muscles and gastric juices which are located in the walls of your stomach. The gastric juices are made up of hydrochloric acid, water, and mucus- and the main enzyme inside of your stomach is what is known as pepsin, which needs to be surrounded in an acidic setting in order to do its job, that is to break down protein. Once the bolus has been inside of your stomach for long enough it begins to form into a liquid called chyme, and what keeps the chyme from flowing back into our esophagus are ring shaped muscles known as sphincters located at the beginnings and ends of the stomach and they have the task of controlling the flow of solids and liquids.
The pancreas is an important organ in digest system. This organ controls human sugar levels and produces a special juice that release the nutrients from food. It is located behind stomach and hormones is helps to break down the food. It aids digestion by producing a special tonic made of water, sodium bicarbonate and digestive enzyme. Sodium bicarbonate neutralizes the stomach is natural acidity, so these digestive enzymes can perform their jobs. Main function of endocrine of pancreas is to produce the chemicals or hormones that regulate blood sugar. Exocrine of pancreas function is to produce enzymes that help to digest food that human eat. The cell of endocrine pancreas also known as Islets of Langerhans which secrete insulin and glucagon.
The exocrine function of the pancreas is that it produces enzymes that aids in the digestion of food. There are three important enzymes that are crucial in helping with digestion. The first digestive enzyme is amylase. Amylase function is to break down carbohydrates. The amylase enzyme is made in two places: the cells in the digestive tract that produces saliva and the main one specifically found in the pancreas that are called the pancreatic amylase (Marie, Joanne; Media Demand, “What Are the Functions of Amylase, Protease and Lipase Digestive Enzymes”). The amylase in the pancreas passes through the pancreatic duct to the small intestines. This amylase in the pancreas completes the process of digestion of carbohydrates. Consequently, this leads to the production of glucose that gets absorbed into the bloodstream and gets carried throughout the body. The next enzyme that aids in digestion of food is protease. While amylase breaks down carbohydrates, protease breaks down protein. Protease breaks down protein into the building block form of amino acids. The three main proteases that it produces are: pepsin, trypsin and chymotrypsin (Marie, Joanne; Media Demand, “What Are the Functions of Amylase, Protease and Lipase Digestive Enzymes”). Pepsin does not occur in the pancreas but it is the catalysis in starting the digestion of proteins. Trypsin and chymotrypsin are the two proteases that occur in
kidney. The main functions of the pancreas is to secrete alkaline juice with enzymes, amylase
The pancreas is an organ that secretes enzymes made by the exocrine cells into the small intestines which aids in digestion. The pancreas also produces insulin which is a hormone that regulates blood sugar. Pancreatic Cancer is a type of disease in which cancerous cells form in the pancreas. The cancerous cells usually first form and attack the exocrine cells. It is predicted that about 55,440 people will be diagnosed with pancreatic cancer in 2018. It is also predicted that about 44,330 people will die due to pancreatic cancer in 2018.
The pancreas regulates blood glucose levels and plays a key role in metabolism. The pancreas helps break down food in the small intestine by digestive juices and enzymes. One of the hormones the pancreas produces is insulin. This hormone is responsible for regulating glucose. All the cells in the body requires glucose for energy. If your body doesn’t produce enough insulin or doesn’t properly make use of it than, the glucose builds up in the bloodstream. This can lead to hyperglycemia which is a deficiency of insulin secretion or decrease sensitivity of receptors on the target cells. Diabetes mellitus condition can exist in three different forms, type one, type two, and gestational diabetes mellitus. Type one is also called insulin dependent
“We don’t know how strong we are until being strong is the only choice we have.” Pancreatic cancer is a very scary disease and is very life threatening. Any gender or age can be diagnosed with pancreatic cancer. This disease has killed very innocent people over the years, and continues to. Because of the rising number of people being diagnosed with pancreatic cancer, scientists study the pancreas more in depth to identify early signs, symptoms, and treatments of this horrible disease.
The digestive system is a very important system in the human body. It is a group of organs that work together to turn food into energy and nutrients in the entire body. The food that was chewed in a humans’ mouth now passes through a long tube that is inside of the body that is known as the alimentary canal. The alimentary canal is made of the oral cavity, pharynx, esophagus, stomach, small intestines, and large intestines. Those few things are not the only important accessories of the digestive system there is also the teeth, tongue, salivary glands, liver, gallbladder, and pancreas.
