What is the function of an earthworms intestine?
The intestine aids in the digestion. It also absorbs and transfers nutrients and water into the bloodstream.
What function affects the efficiency of food absorption by folds of grasshopper and earthworm digestive tube?
The digestive tube structure in both earthworms and grasshoppers consists of several folds. These folds affect the efficiency of food absorption by increasing the surface area.
When you die does the small intestine shrink?
No, the length increases. When you are alive, the muscles are contracted in folds, and when you die, these folds relax, expanding the small intestine.
What are Folds in the small intestine called?
permanent folds are called plicae circulares temporary folds are called rugae.
What do you find in the earthworms gizzard crop and intestine?
food
Deep folds of the mucosa and submucosa that extend completely around the circumference of the small intestine?
circular folds
WHAT ARE TINY FINGERLIKE PROJECTIONS THAT COVER THE FOLDS OF UR SMALL INTESTINE?
The villi are the tiny finger-like projections that cover the folds of the small intestine. The singular of villi is villus.
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.
What are the deep ridges in the small intestine mucosa?
The circular folds or plicae circularis are the permanent folds or ridges of the mucosa.
What are the inner folds of the small intestine called?
They are called "plicae circulares"
Which of these forms large surface area of the small intestine?
folds and villi
Why does the large intestine have many folds and bumps?
The large intestine has folds and bumps, such as haustra and taeniae coli, to increase its surface area for better absorption of water and nutrients. These structures also help in the movement of feces through the intestine by promoting segmentation and peristalsis. Additionally, the folds and bumps enable the large intestine to expand and contract as needed to accommodate varying amounts of waste material.
