Product Information

Absorbing Cells: In contrast to goblet cells, absorbing cells are smaller in size. They play a pivotal role in the absorption of digested nutrients. Similar to goblet cells, their nuclei are also situated near the base. This article aims to give an overview of the anatomy and function of the digestive tract. Details regarding neurovascular supply, histology, and clinically significant points regarding each segment of the digestive tract can be found in the respective articles. It will also briefly mention a few elements of the abdominal examination. 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 You may think digestion begins the moment you take a bite. But in some case, it starts even before that. The sight, smell, or thought of food can be enough to trigger your salivary reflex. That’s why your mouth waters when you’re hungry. Saliva is also produced with the chewing motion. It moistens and lubricates food, making it easier to swallow.

The pancreas is an intricately branched, flattened gland, exhibiting a pale hue. It is strategically positioned in the mesentery, nestled between the stomach and the duodenum. The pancreas is connected to the common bile duct, into which its pancreatic ducts open. This connection is often referred to as the hepatopancreatic duct due to its association with both the liver and the pancreas. It’s crucial to note that bile, while essential, does not contain digestive enzymes. Its primary function is to emulsify fats, making the liver a non-digestive organ in a strict sense.The epiglottis closes off the larynx to prevent food from entering the airway. The vocal cords are also adducted as an additional protective measure. It contains glands that are related to it. The glands are located outside of the gastrointestinal system and are linked to it through ducts like salivary glands, liver and pancreas.

A structure at the bottom of the stomach known as the pyloric sphincter controls the entry of chyme into the first part of the small intestine, called the duodenum. Ducts from the gall bladder and pancreas feed fluids rich in bile salts and digestive enzymes into the duodenum. In addition, some of the cells lining the small intestine produce a fluid known as ‘succus entericus’ made up mostly of water, mucus and sodium bicarbonate.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.
