Part Of Digestive System And Their Functions – When most people think about their digestive systems, their first thoughts usually go to foods that make their stomach happy. Although the stomach is an integral part of the digestive system, it is not the only piece worth knowing about.

Here at Tampa Bay Colorectal Clinic, we focus primarily on the lower digestive tract, but the entire system is important in maintaining our bodies and keeping us alive and healthy.

Part Of Digestive System And Their Functions

This is a very important device, and its proper function is of paramount importance to the overall health of the patient. Let’s take a look at the different parts of the digestive system and the roles they play in the digestive process.

Accessory Organs Of Digestion

This is where foods and drinks begin their journey through the system. In fact, digestion begins as soon as it enters the mouth; Chewing with your teeth breaks food into smaller pieces, and saliva begins breaking down complex carbohydrates into simpler sugars.

The pharynx is probably one of the lesser-known parts of the digestive system. In your neck there are two separate “tubes” that converge at the pharynx. This part of your throat is responsible for directing food and drinks into your esophagus rather than your lungs, keeping your food and air separate. Each time you swallow, the bolus is directed from the pharynx into the esophagus.

The esophagus is about eight inches long and is a long muscular tube that connects the pharynx to the stomach. The esophagus produces muscle contractions in a downward direction to help direct the movement of the food bolus into the stomach. When these contractions fail or are inconsistent, some people experience dysphagia.

At the connection between the esophagus and the stomach, there is a small muscular opening that can be closed to prevent acid from refluxing into the esophagus. In some patients, this sphincter can weaken, causing heartburn and gastroesophageal reflux.

Digestive System Anatomy And Physiology

While no part of the digestive system is more important than another, the stomach plays a large role in the digestion process. This organ uses high acidity to convert food into chyme – a liquid food substance that can be further digested in the next part of the digestive tract.

Divided into three parts (duodenum, jejunum, and ileum), the small intestine is the 22-foot-long portion of the digestive tract responsible for extracting vital nutrients from the chyme. When nutrients are extracted through the microvilli, they enter the bloodstream directly. The pancreas and gallbladder are also important organs that attach to the duodenum. They contribute the enzymes and means needed to break down the complex fats in the food we eat.

The large intestine is the organ that finishes the digestive process. This tube is about five feet long, and its main purpose is to extract any remaining fluid from the debris that enters it. Contrary to popular belief, the digestive process does not stop when remaining undigested food enters the colon.

In fact, the large intestine is where the majority of beneficial gut flora lives. Although your body can no longer extract any more nutrients, the bacteria in your colon are now starting to work. This is where the gas is created. A healthy large intestine contains many beneficial bacteria that break down fiber and release vitamins such as B and K.

The Digestive System

This part of the colon is responsible for storing stool for excretion. The rectum is about five to six inches long. As it expands, stretch receptors that signal bowel movement are activated.

The last few centimeters of the rectum connect to the outside of the body at the anal sphincter. This area is the last stop for food on its way through the body. After secretion, the journey is over!

Here at Tampa Bay Colorectal Clinic, we offer many colorectal services, with a primary focus on the colon, rectum, and anus. If you are experiencing any of these colon and rectal symptoms, it may be time to schedule a consultation with our colorectal specialists here in Tampa Bay. Embark on a fascinating journey through the digestive tract with a guide to digestive system anatomy and physiology. Nursing students, taste the complexity of the processes that turn bites into energy, and let curiosity guide your exploration.

The digestive system organs can be divided into two main groups: those that form the alimentary canal and the accessory digestive organs.

The alimentary canal, also called the gastrointestinal tract, is a continuous, hollow muscular tube that runs through the abdominal body cavity and is open at both ends. Its devices include:

The role that teeth play in food processing needs little introduction; We chew or chew by opening and closing our jaws and moving them from side to side while constantly using our tongue to move food between our teeth.

Specifically, the digestive system takes in food (swallows it), breaks it down physically and chemically into nutrient molecules (digests it), absorbs the nutrients into the bloodstream, and then rids the body of the indigestible remains (defecation).

The activities that occur in the mouth, pharynx, and esophagus are eating food, breaking down food, and pushing food.

The sight, smell, and taste of food stimulate parasympathetic nervous system reflexes, which increase the secretion of gastric juice by the stomach glands.

What is finally delivered to the large intestine contains a few nutrients, but these remains still have an additional 12 to 24 hours to spend there.

Age-related changes in the gastrointestinal tract include decreased saliva, decreased esophageal and gastric motility, decreased gastric emptying time, decreased intrinsic factor production, and decreased intestinal absorption, motility, and blood flow. In addition, tooth enamel becomes harder and more brittle, making teeth more susceptible to fractures.

Health promotion education for older adults includes preventive dental care and effective oral hygiene, proper diet and adequate fluid intake, regular bowel maintenance, and the importance of colorectal cancer screening.

As is the case with all body systems, the digestive system does not work in isolation; It works cooperatively with other body systems. Take, for example, the interrelationship between the digestive and cardiovascular systems. Arteries supply the digestive organs with oxygen and manufactured nutrients, and veins drain the digestive system. These intestinal veins, which form the hepatic portal system, are unique; It does not return blood directly to the heart. Instead, this blood is diverted to the liver where its nutrients are offloaded for processing before the blood completes its cycle back to the heart. At the same time, the digestive system provides nutrients to the heart muscle and vascular tissue to support their function. The interrelationship between the digestive and endocrine systems is also crucial. Hormones secreted by many endocrine glands, as well as endocrine cells in the pancreas, stomach, and small intestine, contribute to controlling the digestive process and metabolizing nutrients. In return, the digestive system provides the nutrients needed to fuel endocrine function. Table 1 provides a quick overview of how these other organs contribute to the functioning of the digestive system.

Digestive System Processes

The easiest way to understand the digestive system is to divide its organs into two main categories. The first group is the organs that make up the alimentary canal. The accessory digestive organs constitute the second group and are essential for regulating the breakdown of food and the assimilation of its nutrients in the body. Accessory digestive organs, despite their name, are essential for digestive function.

Also called the gastrointestinal (GI) tract or gastrointestinal tract, the gastrointestinal tract (trophic = “to nourish”) is a one-way tube that is approximately 7.62 meters (25 ft) in length during life and approximately 10.67 meters (35 ft) in length when measured after death Once smooth muscle tone is lost. The main function of the digestive tract organs is to nourish the body. This tube starts at the mouth and ends at the anus. Between these two points, the channel is modified to include the pharynx, esophagus, stomach, small and large intestine to suit the functional needs of the body. Both the mouth and anus are open to the external environment; Therefore, food and waste inside the digestive tract are technically outside the body. Only through the process of absorption do the nutrients in food enter the body’s “inner space” and nourish it.
