Question

What type of junction would you expect to find most commonly in the intestinal tract, where exchange across epithelium is common?

A) tight junctions
B) loose junctions
C) gap junctions
D) I junctions
E) desmosomes

Answer 1

Tight junctions are the type of junction that you would expect to find most commonly in the intestinal tract, where exchange across epithelium is common.

Step-by-step explanation:

Tight junctions are the type of junction that you would expect to find most commonly in the intestinal tract, where exchange across epithelium is common. These junctions form a watertight seal between adjacent animal cells, preventing materials from leaking between the cells. They are typically found in tissues that line the internal organs and cavities. For example, the tight junctions of the epithelial cells lining the intestinal tract prevent food from leaking between cells into the body.
