What is Typhlosolar region?

Typhlosolar Region: It is the 2nd or middle part of the intestine which extends from the 27th segment to last from the 25th segment. It has both villi and typhlosole. The typhlosole is a vascular and glandular fold that increases the absorptive surface area of the intestine.

What is the purpose of the typhlosole in the earthworm?

Its function is to increase intestine surface area for more efficient absorption of digested nutrients. In different earthworm families, the typhlosole appears to have multiple origins.

Between which segments typhlosole is found and what is its function *?

Presence of an internal fold of dorsal wall of intestine is the characteristic feature of the intestine and this typhlosole is present between 26th and 95th segments which increases the area for effective absorption of digested nutrients.

Do all earthworms have a typhlosole?

The typhlosole is not physically identical in different earthworms, and in fact, some earthworms do not have one at all. In addition, earthworms are not the only animals to have a typhlosole; other animals that exhibit a typhlosole include mollusks and oysters.

What is the function of the typhlosole in an earthworm quizlet?

What is the function of the typhlosole? Increases the surface area of the intestine, which increases the rate of nutrient absorption.

Does the typhlosole help in nutrient absorption in earthworms?

An important part of the earthworm’s digestive system, the typhlosole increases the surface area that the worm has available to efficiently absorb necessary nutrients from the food it digests. The typhlosole is not physically identical in different earthworms, and in fact, some earthworms do not have one at all.
