What is the difference in function between the rugae and the circular folds?
Rugae and circular folds are both structures found in the digestive system, particularly in the stomach and small intestine, respectively. Rugae are thick folds of the stomach lining that allow for expansion as the stomach fills with food, aiding in the mechanical digestion process. In contrast, circular folds, or plicae circulares, are permanent folds in the small intestine that increase surface area for nutrient absorption by slowing down the passage of food and enhancing interaction with digestive enzymes. Thus, while rugae assist with storage and mixing in the stomach, circular folds optimize absorption in the intestines.
Why do you think most digestion takes place in the small intestine?
First of all, this is not an opinion question. It is purely factual. Most digestion takes place in the small intestine because that is where nutrients are absorbed and some of the food is broken down by chemicals (although some of that happens in the stomach, as well). The large intestine only absorbs water.
Where are digested foods absorbed?
The digestion first starts in the mouth and the food is absorbed in the small intestine, and the water and minerals go to your large intestine:)learned this in biology, last week =)
9 What is the function of the rugae in the stomach and villi in the small intestine?
both rugae and villi are specialized "folds". the rugae allow your stomach to expand when you eat (like a balloon) and the villi increase the surface area in your small intestine for nutrient absorption
What are the hair like projects on villi called?
The hair-like projects on villi are called microvilli. These tiny, finger-like extensions increase the surface area of the villi, enhancing the absorption of nutrients in the small intestine. Microvilli are covered in a brush border of enzymes that aid in digestion and nutrient absorption.
What structure slows down the progress of chyme through the small intestine to allow time for digestion?
The structure that slows down the progress of chyme through the small intestine is the circular folds, also known as plicae circulares. These folds increase the surface area for absorption and create turbulence in the chyme, which enhances the mixing of digestive enzymes and nutrients. This design ensures that chyme spends sufficient time in each section of the small intestine for optimal digestion and absorption of nutrients.
The primary organ responsible for absorption of products of digestion?
The primary organ of digestion and absorption of nutrients is the small intestine, especially the duodenum.In general, you could say the stomach breaks down the food, the small intestine digests and absorbs the food, and the large intestine absorbs water.

Long convoluted tube where chemical digestion is completled?
The small intestine is a long convoluted tube where the majority of chemical digestion and nutrient absorption takes place in the body. It is lined with villi and microvilli that increase the surface area available for absorption of digested nutrients into the bloodstream. Various enzymes and bile from the pancreas and liver play crucial roles in breaking down food molecules in the small intestine.

Is rugae a structural modification of the small intestine to increase surface area?
No, rugae are not a structural modification of the small intestine; instead, they are folds found in the stomach that allow it to expand when filled with food. The primary structural modifications of the small intestine that increase its surface area are villi and microvilli, which enhance nutrient absorption. These modifications work together to maximize the intestinal surface area, facilitating efficient digestion and absorption.
What is the definshion for small intestint?
The small intestine is a long, coiled tube in the digestive system that connects the stomach to the large intestine. It is primarily responsible for the digestion and absorption of nutrients from food. The small intestine is divided into three parts: the duodenum, jejunum, and ileum. Its inner surface is lined with villi and microvilli, which increase the surface area for nutrient absorption.
The type of epithelial cells most commonly associated with absorption is the small intestine is what?
The type of epithelial cells most commonly associated with absorption in the small intestine are simple columnar epithelial cells. These cells are equipped with microvilli, which increase the surface area for absorption, facilitating the uptake of nutrients. Additionally, goblet cells interspersed among them secrete mucus to aid in digestion. Overall, this structure enhances the efficiency of nutrient absorption in the small intestine.
Where does most of the chemical digestion take place in humans?
It is the Duodenum!Actually, most chemical digestion, in humans, takes place in the small intestine.Chemical digestion takes place in the small intestine, the stomach and the mouth.
What do villi increase?
Villi increase the rapid absorption of food away from the small intestine.
Finger like srutures that cover the inner of the small intestine?
The finger-like structures covering the inner lining of the small intestine are called villi. Villi are specialized structures that increase the surface area of the small intestine, allowing for better absorption of nutrients from digested food into the bloodstream. These structures play a crucial role in the process of digestion and nutrient absorption.
