Question

what is an epithelium and define homeostasis​

Answer 1

Answer:

EPITHELIUM=The thin tissue forming the outer layer of a body's surface and lining the alimentary canal and other hollow structures.

HOMEOSTASIS=The process by which the body reacts to changes in order to keep conditions inside the body

Answer 2

Epithelium is one of the four basic types of animal tissue, along with connective tissue, muscle tissue and nervous tissue. Epithelial tissues line the outer surfaces of organs and blood vessels throughout the body, as well as the inner surfaces of cavities in many internal organs. An example is the epidermis, the outermost layer of the skin.

Homeotasis is the tendency towards a relatively stable equilibrium between interdependent elements, especially as maintained by physiological processes.
