Question:

Large intestine 7 Haustra

Score 10 of 10

Question:

Characteristic components of the large intestine

Response:

Fill in the words in the correct places.

The taeniae of the colon are the outer (= longitudinal) muscle layers of the colon lying along the colon, consisting of three long strips of muscle. They contract the colon, causing bulges of the colon, the so-called haustra. In between the bulges there are folds called semilunar folds. These folds are dynamic, they come and go with the contractions of the colon. Don't mistake them for the folds of the small intestine, the circular folds. These are permanent
