Chemical digestion and absorption of nutrients occurs in the small intestine.
The small intestine is the organ responsible for both chemical digestion and absorption of nutrients from food. Enzymes and bile break down the food, while nutrients are absorbed through the small intestine's lining into the bloodstream for distribution to the body's cells.
The pancreas is the accessory organ to digestion that produces most of the digestive enzymes. These enzymes are released into the small intestine to help break down carbohydrates, proteins, and fats in food for absorption.
In earthworms, the digestive organ responsible for digestion and absorption of nutrients is the intestine. The intestine is a long, coiled structure where food is further broken down by enzymes and where the absorption of nutrients into the bloodstream takes place. The presence of typhlosole, a fold in the intestinal wall, increases the surface area for absorption, making the process more efficient.
The two processes that occur are digestion and absorption. Digestion is the process by which your body breaks down food into small nutrient chemicals. While absorption is the process in which when the small nutrient molecules go through a wall of the digestive system and into the blood.
The first part of the small intestine where bile and enzymes mix with food from the stomach is the duodenum. This process is crucial for further digestion and nutrient absorption in the body.
The large intestine is mechanical digestion; it absorbs water and is involved in peristalsis. It has nothing to do with enzymes, which is chemical digestion.
Digestion is the process of breaking down food into smaller molecules so they can be absorbed by the body. This typically involves mechanical digestion (chewing) and chemical digestion (enzymes breaking down nutrients). Absorption occurs in the small intestine, where nutrients are absorbed into the bloodstream for distribution to cells throughout the body.
Fats in chyme stimulate the secretion of bile from the gallbladder and enzymes from the pancreas to help with fat digestion and absorption in the small intestine.
The structures that add enzymes to chyme in the small intestine are the pancreas and the intestinal mucosa. The pancreas secretes pancreatic enzymes such as proteases, lipases, and amylases into the small intestine to aid in digestion. Additionally, the intestinal mucosa produces enzymes to further break down nutrients for absorption.
The pancreas produces and secretes digestive enzymes that aid in the breakdown of carbohydrates, proteins, and fats in the small intestine. Additionally, the liver produces bile, which is stored in the gallbladder and released into the small intestine to help with the digestion and absorption of fats.
Bile is produced by the liver and stored in the gallbladder, where it helps in the digestion and absorption of fats in the small intestine. The pancreas produces digestive enzymes that help break down carbohydrates, proteins, and fats in the small intestine to facilitate nutrient absorption. Both bile and pancreatic enzymes play crucial roles in the digestive process.
