The principles of digestion and absorption are among the most important topics covered by NEET, which covers a wide range of topics. The chapter is so vast and we recommend you to give extra care to this concept.
Basidia’s NEET Biology- Digestion and Absorption video lessons include all of the main topics and concepts covered in the examination. More NEET video lectures on other subjects can be found on Basidia’s YouTube page.
What is Digestion?
It is the process by which complex food is broken down into simpler forms in order to improve nutrient absorption and energy release in the body. The alimentary canal and digestive glands are part of the digestive system. The alimentary canal, which travels from the esophagus to the rectum, is made up of four layers: serosa, mucosa, muscularis, and submucosa. Glands are essential for digestion. There are five types of glands in total, and they are as follows:
- Salivary glands.
- Gastric Glands.
- Intestinal Glands.
The process of digestion begins in the mouth when masticated food is combined with saliva. In turn, it produces a bolus, or tiny quantity of food, which travels down the throat and esophagus by deglutition or swallowing. Following that, the digestive enzymes present in the alimentary canal combine with the meal and begin the digestion process.
What is Absorption?
The bio-macromolecules are broken down in the duodenum and absorbed in the jejunum and ileum. The undigested food travels to the large intestine, where it is absorbed along with some water and minerals. Food absorption occurs by diffusion owing to a concentration gradient or via aided transport by a carrier protein.
