Tissue Types Quiz

What characteristic of epithelial tissue allows it to function without its own blood supply?

• It uses oxygen and nutrients via diffusion from capillaries.

• It has a rich blood supply.

• It stores oxygen internally.

• It does not require oxygen.

What is the function of the basal lamina in epithelial tissue?

• It acts as a filter and provides scaffolding for cell migration.

• It stores nutrients for the tissue.

• It supplies blood to the tissue.

• It prevents cell division.

What is the role of the apical surface in epithelial tissue?

• It is the upper free surface exposed to the body's exterior or cavity of an organ.

• It is the lower surface attached to the basement membrane.

• It stores nutrients for the tissue.

• It prevents cell migration.

What is the primary function of a gap junction?

• To form a narrow passageway between two cells for molecules or ions to move

• To tightly bind the lipid portions of two plasma membranes

• To prevent the separation of cells in areas of high stress
