What 2 things happen in the small intestine?
Chemical digestion and absorption of nutrients occurs in the small intestine.
Where are enzymes secreted from in digestion?
Enzymes in digestion are primarily secreted by the salivary glands, stomach, pancreas, and small intestine. Salivary glands release enzymes like amylase during chewing, while the stomach secretes pepsin for protein digestion. The pancreas produces a variety of digestive enzymes, including lipase, proteases, and amylase, which are released into the small intestine to aid in the breakdown of carbohydrates, proteins, and fats. Additionally, the cells lining the small intestine secrete enzymes that further assist in digestion and nutrient absorption.
Organ responsible for chemical digestion and absorbtion of food?
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.
What is the accessory organ to digestion that produces most of the digestive enzymes called?
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.
Which digestive organ is responsible for digestion and absorption of nutrients in earthworms?
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.
What two digestive processes occur in the small intestine?
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.
What is the first part of the small intestine where bile and enzymes mix with the food as it comes out of the stomach?
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.
Where does the pancreas release digestive enzymes in to?
The pancreas releases digestive enzymes into the small intestine, specifically the duodenum, which is the first section of the small intestine. These enzymes, including amylase, lipase, and proteases, aid in the digestion of carbohydrates, fats, and proteins. The release of these enzymes is triggered by the presence of food in the stomach and the release of hormones like secretin and cholecystokinin. This process is essential for the proper digestion and absorption of nutrients from food.
What organ produces enzymes that help in digestion of protiensfatsand carbohydrates?
The pancreas is the organ that produces enzymes essential for the digestion of proteins, fats, and carbohydrates. It secretes digestive enzymes such as proteases for proteins, lipases for fats, and amylases for carbohydrates. These enzymes are released into the small intestine, where they aid in breaking down food substances for absorption. Additionally, the pancreas also produces bicarbonate to neutralize stomach acid in the small intestine.
Is the large intestine mechanical digestion or chemical?
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.
What is Outline the basic principles of digestion and absorption?
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.
What do fats in chyme stimulate the secretion of?
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.
