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.
How does a vili work?
A villi is a finger-like projection in the small intestine that increases surface area for absorption of nutrients. It contains blood vessels and lacteals to help absorb nutrients into the bloodstream. Villi play a crucial role in the digestive process by maximizing the efficiency of nutrient absorption.
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.
Which part of the digestive system contains structural adaptations called villi that increase the surface area for the absorption of nutrients?
No
How is the absorption of nutrients facilitated in the digestive system?
The absorption of nutrients in the digestive system is facilitated through the lining of the small intestine, which is covered in tiny finger-like projections called villi. These villi increase the surface area for nutrient absorption and contain specialized cells that transport nutrients into the bloodstream for distribution throughout the body.
What is the function of the typhlosole on a earthworm?
The typhlosole is a fold in the intestinal wall of an earthworm that increases the surface area for absorption of nutrients. It helps in the digestion and absorption of food in earthworms by providing more surface area for enzymes to break down food particles and for nutrients to be absorbed.
Does the presence of villi increase the surface area of the mucosal lining for absorption?
Yes, the presence of villi significantly increases the surface area of the mucosal lining in the intestines, enhancing the efficiency of nutrient absorption. Villi are small, finger-like projections that extend into the intestinal lumen, allowing for a larger surface area to come into contact with digested food. This adaptation facilitates the absorption of nutrients and contributes to the overall effectiveness of the digestive process.
What plant part increases absorption capacity of roots?
Root hairs are the plant part that increases the absorption capacity of roots. These tiny hair-like structures on the surface of roots significantly increase the surface area available for absorbing water and nutrients from the soil.
Which part of the digestive system is primarily responsible for absorbing nutrients?
The small intestine is the part of the digestive system responsible for absorbing most of the nutrients. The villi are the structural feature that maximize surface area for absorption.
How thousands of folds and sub-folds in the small intestine help in digestion?
It increases the surface area available for absorption of digestion nutrients.
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.
Do villi absorb dissolved food?
It increases the surface area of your gut wall (because there are millions) and make absorption of nutrients quicker. Hope this helps
