What Does The Pancreas Do In A Human Body

What Does The Pancreas Do In A Human Body – The pancreas is a relatively small, elongated organ located in the abdominal cavity and behind the stomach. One of the things that makes the pancreas unique is that it is part of both the digestive system and the endocrine system. However, it can also be understood by its two categories of functions: exocrine and endocrine. Exocrine function means that the substance is secreted from a duct, while endocrine means that the substance is secreted directly into the bloodstream. In this way, the pancreas acts both as an organ in the digestive system and as a gland in the endocrine system.

In adults, the pancreas is usually about 12-14 centimeters long and tapers as it extends from behind the stomach to the upper left side of the abdomen near the spleen. Anatomically it can be divided into four parts: head, neck, body and tail. The head is the widest part of the pancreas and is located adjacent to the duodenum, the first part of the small intestine. The neck is where the pancreas begins to taper down toward the body, the large middle portion being near the superior mesenteric artery. The tail is the tip of the pancreas that is closest to the spleen.

The location of the pancreas, near the stomach, small intestine and liver, makes it ideally suited for its important role in digestion. The main way the pancreas contributes to digestion is by producing and secreting the right biochemical compounds at the right time. This happens due to various specific functions:

During the digestion process, food that makes its way to the stomach is broken down through peristalsis and stomach acids. The resulting material, a mostly liquid mixture called chyme, then enters the small intestine in the duodenum. In the duodenum, several chemicals from the pancreas enter the digestive tract through the pancreatic ducts. The pancreas makes about 8 ounces of this digestive juice each day:

Another major aspect of digestion that the pancreas is involved with is blood sugar regulation. However, instead of releasing chemicals directly into the digestive tract, the pancreas secretes them into the bloodstream via the

. Also, instead of enzymes that aid in digestion, the pancreas releases messenger hormones that affect the digestive system as a whole:

Because the pancreas is such a multifaceted organ, this also means that there are a number of ways in which abnormal function can lead to health problems. Below are some of the most common conditions related to the pancreas:

The location of the pancreas, located behind the abdomen, makes it difficult to evaluate during physical examination. As a result, the doctor may use a variety of imaging tests and pancreatic function tests. MRIs, CT scans, and ERCP (endoscopic retrograde cholangiopancreatography) are all potential options for assessing the health of the pancreas. Depending on the nature of the problem, more tests may be needed.

As stated above, the main problems that can occur with the pancreas are diabetes, pancreatitis, and pancreatic cancer. Diabetes treatment has evolved over time, but the same basic idea still applies: replace insufficient or ineffective insulin with insulin injections. Regarding pancreatitis, it can usually be resolved with dietary changes (for example, drinking less alcohol) or medication. However, in the case of pancreatic cancer, standard cancer treatments such as chemotherapy, radiation and surgery (pancreatectomy) are common approaches.

The pancreas is an important part of the digestive process that is sometimes overlooked; the enzymes and hormones secreted by the pancreas are crucial for maintaining metabolic balance and controlling blood sugar.

This review aimed to analyze the scientific literature on pancreatic diseases (especially exocrine pancreatic insufficiency). This review also describes the correlation between the physiological fitness of the pancreas and obesity. The influence of the exocrine function of the pancreas on the development of the body of adults and adolescents was also described. The results of piglet studies available in the literature have been cited as an established model used to optimize treatments for pancreatic diseases in humans. The pancreas has an exocrine and hormonal function. Consequently, it is one of the key internal organs in animals and humans. Pancreatic diseases are usually severe and especially distressing. A properly composed diet and taken nutritional supplements significantly improve the patient’s well-being, as well as the course of the disease. Therefore, nutrition and a healthy lifestyle have a positive effect on maintaining the optimal physiological efficiency of the pancreas.

Diabetes And The Pancreas: Insulin, Complications, And Function

The pancreas is a glandular organ that affects the functioning of the entire body. The manifestation of pancreatic insufficiency is the inability of the pancreas to biosynthesize and/or secrete digestive enzymes in an amount sufficient to digest and absorb food components in the intestines. Insufficiency usually occurs as a result of damage to the pancreas, which can be caused by various clinical conditions, for example, recurrent acute pancreatitis, chronic pancreatitis, diabetes, autoimmune diseases, after pancreatectomy surgery. It happens that such a failure is the result of cancer of the pancreas or the gastrointestinal tract. In children, it is most often associated with cystic fibrosis (about 90% of patients) or with a rare genetic disease such as Schwachmann-Diamond syndrome. Pancreatic insufficiency usually presents with malabsorption, malnutrition, vitamin deficiency and weight loss (or inability to gain weight in children). Treatment is about treating the underlying cause, preventing further damage to the pancreas, and relieving symptoms.

In this paper, the authors present the impact of a non-functional pancreas on higher mammalian organisms. Based on the analysis of the literature, the influence of the exocrine function of the pancreas on the development of the adult and adolescent organism was described. Individual diseases that directly affect the health of the pancreas are listed and briefly described. The correlation between pancreatic diseases and factors such as diet, lifestyle and obesity was also discussed.

Anatomically, the pancreas is divided into a head, body, and tail (Figure 1). The parenchyma of the pancreas has a lobular structure and contains numerous secretory vesicles, which make up 80-85% of the mass of the organ. The excretory ducts are very important for the functioning of the pancreas. Each bubble has an output wire that connects to the others and connects to the main channel. The main duct is the pancreatic duct, which begins in the tail of the pancreas, passes through the entire length of the organ and finally enters the duodenum through the greater papilla (Vatera). Apart from it, there is also the accessory pancreatic duct which in about 70% of people connects to the pancreatic duct and finally the substance secreted by the pancreas, transported through both ducts, goes to the so-called greater duodenal papilla. In the histological structure of the pancreas, two basic elements are distinguished: pancreatic islets (or islets of Langerhans – their number can reach up to 2 million and they produce pancreatic hormones) and secretory cells, which make up the rest of the organ and are responsible for secreting pancreatic juice and pancreatic enzymes.

The pancreas has two essential and very important functions in the body: endocrine (production of hormones that regulate blood sugar levels and gland secretion) and exocrine (digestive gland function) (Yamada et al., 2005). Endocrine activity is carried out by the islets of Langerhans and includes the production of hormones such as insulin, proinsulin, amylin, C-peptide, somatostatin, pancreatic polypeptide (PP) and glucagon. Insulin helps lower blood sugar and glucagon causes blood sugar to rise. On the other hand, exocrine activity consists of the production of enzymes that are part of the iso-osmotic, alkaline pancreatic juice and support the digestion of food in the intestine. Intravesical cells produce enzymatic components of the juice, which enters the duodenum through the pancreatic ducts. In addition, mucus is secreted into the pancreatic ducts through the goblet cells. The composition of pancreatic juice includes enzymes that digest proteins, fats, carbohydrates and nucleic acids, as well as electrolytes and a small amount of mucus (DÄ…browski et al., 2007).

Diabetes And Endocrine Function

Enzymes such as trypsin, chymotrypsin, carboxypeptidase and elastase belong to the group of proteolytic enzymes (they digest proteins). Trypsin and chymotrypsin are secreted in the form of proenzymes: trypsinogen, chymotrypsinogen. Lipolytic enzymes of the pancreas are lipase, phospholipase and esterase, which digest fat. The glycolytic enzymes (digesting carbohydrates) are lactase and amylase, which break down starch into maltose, maltotriose, and dextrins. Nucleolytic enzymes include ribonuclease and deoxyribonuclease, which break down nucleic acids into mono- and oligonucleotides. Food consumption and a neurohormonal mechanism regulate the secretion of digestive enzymes. The pancreas secretes pancreatic juice in a volume of about 1-4 liters per day, and this amount depends on the food consumed.

The central nervous system and hormones regulate the exocrine function of the pancreas. It is believed to be hormones such as secretin and cholecystokinin (CCK).
