Describe accurately the the basement membrane which underlies epithelial tissues

The basement membrane or basal lamina on which the epithelium form, made by extracellular matrix.

Explanation:

The basement membrane is the layer underlies all epithelia that is made up extracellular matrix secreted by the epithelium cells that provide structural support to the structure of epithelia.

It forms the barrier between epithelial tissues therefore once a epithelial cancer penetrate this basement membrane it will spread to all underlying tissues.

Thus, the correct answer is - The basement membrane or basal lamina on which the epithelium form, made by extracellular matrix.

The basement membrane is form of extracellular matrix that underlies all epithelia. It provides structural support to epithelia and forms a mechanical connection between epithelia and underlying connective tissue.

The basement membrane, or basal lamina, is a sheet of proteins and other substances to which epithelial cells adhere and that forms a barrier between tissues.

Epithelial cancers may have the ability to penetrate through the basement membrane and spread to underlying tissues.

stratosphere: as the altitude increases, the air temperature increases. the stratosphere has a layer of ozone, called the ozone layer. this layer absorbs most of the ultraviolet radiation from sunlight. this results in the stratosphere being warmer.

i think it would be b. tissue because an organ system is a group of organs that work together to perform one or more functions. each does a particular job in the body, and is made up of certain tissues.
