Flowchart Science: The Human Body: The Digestive System

Product Information

The digestive system of a frog comprises several key features that are specialized for its mode of life and diet. Here are the main features:

However, it may be more challenging to di Blood Functions: In embryonic stages, the liver is responsible for red blood cell production. In adults, it aids in the destruction of old erythrocytes. Furthermore, it produces vital blood-clotting agents like prothrombin and fibrinogen and secretes heparin, an anticoagulant. Since stomach acid is so potent, its production needs careful supervision. At the start of a meal, gastric function is just starting to warm up and very little stomach acid is secreted. Peristalsis gently begins stretching and squishing the stomach in preparation for incoming food. Furthermore, the stomach’s mucous epithelium is a hub of activity. It houses multicellular gastric glands that are responsible for secreting the enzyme pepsinogen. In addition to these, there are unicellular oxyntic glands that produce hydrochloric acid, a vital component for digestion. As we move towards the pyloric end of the stomach, there is a noticeable constriction. This region is safeguarded by the pyloric valve, which serves as a gateway into the small intestine. This valve is not just a passive barrier; it is a dynamic circular ring-like sphincter muscle that meticulously regulates the flow of digested food from the stomach to the intestine.

Chyme: mix of broken-down food and digestive juices that leave the stomach and travel through the small intestine. Put your food, water, and orange juice in the stomach. No, not that one. In the plastic bag stomach. The end result is that these nerves send motor signals to the tongue, which moves the bolus against the hard and soft palate, then into the oropharynx (which is also under brainstem regulation). The bolus then continues inferiorly towards the laryngopharynx and the swallowing reflex is initiated at the esophagus. All the actions of swallowing up to this point were under voluntary control; however, the rest of the action is carried out by involuntary peristaltic contractions that travel in a craniocaudal fashion. At the level of the pharynx: Both physical and chemical digestion occurs within the stomach. The continual churning movements of the muscular walls of the stomach mix food with a digestive fluid, known as gastric juice. The small intestine is a vital component of the digestive system, responsible for the absorption of nutrients and the continuation of the digestive process initiated in the stomach. Structurally, it is a long, coiled, and narrow tube, measuring approximately 30cm in length. The small intestine is anchored mid-dorsally to the body wall by mesenteries, ensuring its stability within the body cavity.

Immunological defence: the acidic pH of the stomach aids in dissolving invading pathogens before they are able to cause an infection. Digestive Tract Fact #4 – It takes four to five hours for the stomach to completely empty into the small intestine after a meal. Large Intestine 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 buccal cavity, also known as the oral cavity or mouth, is an essential component of the frog’s digestive system. It serves as the initial point of entry for food and plays a crucial role in the frog’s feeding mechanism. Take a closer look at the digestive system and consider the path your food takes. It is remarkable how your favorite meals are torn apart, liquefied, absorbed, and eventually eliminated by your body. And it’s all to harvest the essential nutrients you need to survive.Following the buccal cavity, the food moves through the pharynx and into the oesophagus, a narrow tube responsible for transporting food to the stomach. The oesophagus then leads to the stomach, where the primary digestion occurs. From the stomach, the digested food progresses into the intestine, where nutrients are absorbed. The remaining undigested food then moves into the rectum and is eventually expelled through the cloaca. Esophagus: This is a short tube that transports food from the mouth to the stomach. It is relatively narrow and serves mainly as a conduit. Now get digesting. Give it a good squeeze and mush the food with the water and acidic orange juice, just like the stomach acid does to the food in your stomach. Transfer the food to the tights, that's the small intestine. Think of the apple. In the afternoon, when you need something to tide you over until the evening meal, an apple is a great choice. Just thinking of the crunchy fruit and the sweet, tangy, juice can make your mouth water.
