What is the necessity of finger like projections in digestive system?
They are there to increrase the surface area so more absorbtion can take place.
How is the digestive surface of a frog increased?
The digestive surface of a frog is increased through the presence of villi in the small intestine. Villi are finger-like projections that line the inner surface of the intestine, increasing the surface area for absorption of nutrients. This allows for more efficient digestion and absorption of nutrients from the food the frog eats.
What are the tiny finger like projections in the digestive system called?
The tiny finger-like projections in the digestive system are called villi. They are located in the small intestine and play a crucial role in increasing the surface area for absorption of nutrients. Each villus is covered in even smaller hair-like structures called microvilli, which further enhance nutrient absorption. Together, they significantly improve the efficiency of the digestive process.
What kind of a cell lines the small intestine and assembles fat?
The small intestine is lined with epithelial cells. These specialized cells have microvilli on their surface, which increase their surface area for absorption. These cells play a key role in the absorption of nutrients and fats from the digestive tract into the bloodstream.
What is the name of the projections on the inner surface of the small intestine?
projections r called ..VILLI
Why are the walls of the small intestine lined with small projections?
The small projections lining the walls of the small intestine are called villi. They increase the surface area of the intestine, which allows for more efficient absorption of nutrients from food into the bloodstream. This helps improve the nutrient absorption process in the digestive system.
What ia villi?
Villi are small finger like projections on the inside of the small intestine, intended to create more surface area. This way more absorption can take place in the digestive process.
What are the 3 different types of map projections?
The three main types of map projections are cylindrical, conic, and azimuthal. Cylindrical projections show the Earth's surface on a cylinder, conic projections project the Earth's surface onto a cone, and azimuthal projections project the Earth's surface onto a plane. Each type has variations that can result in different map distortions.
How does villi affect surface area?
Villi are small, finger-like projections that line the inner surface of the small intestine. They increase the surface area available for absorption of nutrients by extending the intestinal lining, allowing for more efficient nutrient uptake into the bloodstream. The increased surface area provided by villi, along with microvilli (even smaller projections on the villi), significantly enhances the intestine's ability to absorb digested food. This adaptation is crucial for maximizing nutrient absorption in the digestive process.
What projections allow the cell to move or moves substances along the surface of the cell?
Projections that allow the cell to move or to move substances along the surface of the cell are called cilia and flagella. Flagella is a single long hair that allows the cell to swim. Cilia are several projections used for movement across the cell surface.
What does the pyloric caeca do?
the Pyloric ceca secrets digestive enzymes
What are the fingerlike projections that greatly increase the surface are of cells?
stereocilia
