Flowchart Science: The Human Body: The Digestive System

Product Information

Assimilation: The absorbed nutrients are utilized for energy production or assimilated into the body’s structures. Excess glucose may be stored as glycogen, and amino acids may be used for protein synthesis or converted into waste products like urea. Peristalsis helps pump chyme into the small intestine while you eat. Once your meal is over, stomach acid secretion comes to a halt. But there may be excess acid. When too much gastric juice remains in the stomach after a meal, irritation of the stomach lining can occur. To protect itself, the stomach adjusts acid production to stay healthy and keep you comfortable. For its sustenance and functionality, the liver receives blood via the hepatic arterial vein and the hepatic portal vein. These vessels supply the essential materials required for bile production.

Secretin and Pancreozymin: These hormones stimulate the pancreas to release pancreatic juices into the duodenum. The anus is the last part of the digestive tract. It consists of the muscles that line the pelvis (pelvic floor muscles) and two other muscles called anal sphincters (internal and external).Muscular tube that conduct the bolus to the stomach; It has upper sphincter (opens with swallow reflex and allows the bolus to enter the esophagus) and lower sphincter (controls emptying of the esophagus content to the stomach)

The digestive system of the human body comprises a group of organs working together to convert food into energy for the body. Anatomically, the digestive system is made up of the gastrointestinal tract, along with accessory organs such as the liver, pancreas and gallbladder. The hollow organs that make up the gastrointestinal tract (GI tract) include the mouth, stomach, oesophagus, small intestine and large intestine that contains the rectum and anus. Contains structures that start digestion: teeth (choping the food), salivary glands (secrete saliva that contain enzymes that start chemical digestion of sugar and fats), tongue ( detects taste, pushes bolus towards the pharynx) Bile also contains bilirubin, a yellow-orange pigment released by red blood cells as they break down. Your body can’t metabolize bilirubin on its own, so it relies on bacteria to help out. When the bacteria in your small intestine chow down on bilirubin, they produce a dark material called sterobilin. This by product gives stool it’s notable brown color. These features work in concert to ensure that the frog can efficiently capture, ingest, digest, absorb nutrients from, and finally expel the remains of its food. Alimentary Canal Bile: Secreted by the liver, bile is an alkaline fluid that emulsifies fats, neutralizes the acidity of chyme, and stimulates intestinal peristalsis.The frog’s digestive system primarily consists of the alimentary canal and the associated digestive glands. The alimentary canal is a continuous tube that runs from the mouth to the cloaca, facilitating various processes such as digestion, absorption, and mastication. Besides the alimentary canal, the digestive glands play a pivotal role by producing enzymes essential for the digestion of consumed food.

The small intestine is a narrow, coiled tube where the majority of nutrient absorption occurs. It is lined with villi, small finger-like projections that increase the surface area for absorption. The nutrients from the digested food are absorbed through the walls of the small intestine into the bloodstream. Extending from the mouth to the anus, the digestive tract is one of the largest systems in the human body. It contains organs that regulate food intake, its digestion and absorbtion of the useful materia that it contains. In addition to this, the digestive system also eliminates the waste products from food and products from various endogenous metabolic processes. Now, glucose molecules, amino acids, and free fatty acids are available to be absorbed into the blood stream through the villi. The esophagus is a muscular tube extending from the pharynx and behind the trachea to the stomach. Food is pushed through the esophagus and into the stomach by means of a series of contractions called peristalsis.Throughout this process, the frog’s digestive system efficiently converts prey into vital nutrients, ensuring the animal’s survival and energy needs are met. Functions of Digestive system of Frog

It includes the colon (ascending, transverse and descending colon). The purpose of the large intestine is to accept the soupy digestion, remove the water and convert it to faeces. It is located next to the small intestine. The alimentary canal has the main function of food digestion and absorption. It has different organs and parts that help in food digestion. Teeth help in the mechanical breakdown of food and the mouth helps in food intake. The oesophagus helps in carrying the food particles to the stomach. The stomach helps in storing and maintaining the pH of the food. The small intestine absorbs food particles and passes them to blood. The large Intestine helps in extra water absorption from undigested food. Furthermore, as the oesophagus extends downwards, it experiences a noticeable enlargement. This enlargement signifies the point where the oesophagus merges with the stomach, located within the peritoneal cavity. Therefore, the oesophagus serves as a bridge, ensuring that ingested food is efficiently and safely transported from the oral cavity to the stomach for further digestion. The mucous epithelium consists of columnar mucous-secreting gland cells. These glands, embedded in the lamina propria, are invaginations of the mucous epithelium and are known as gastric glands. These glands differ in structure and function in various parts of the stomach.Succus Entericus: The intestinal juice contains a variety of enzymes that further break down polypeptides, disaccharides, and fats into their absorbable monomers. In summary, the cloaca is an essential anatomical structure that manages waste excretion and reproductive functions in certain animals. Its presence ensures that these processes are carried out efficiently and effectively. Feel free to ask your questions or participate in ongoing discussions. Our team of experts, as well as fellow
