How can you tell epithelial tissue from other tissue?
Epithelial tissue has a free surface, a basement membrane, and little intercellular material.
What two factors determine the distance from the free surface to the basal surface in epithelial tissue?
Speed and distance
What types of cell junctions connect cells within tissues?
The apical surface does not have any cell junctions because it is a free surface exposed to things that are not epithelial cells. The lateral surfaces of an epithelial cell, which face the adjacent cells on either side contain tight junctions, adherens junctions, desmosomes and/or gap junctions. The basal surface of an epithelial cell adhere to extracellular materials like the basement membrane. Hemidesmosomes anchor the epithelium to the basement membrane in the basal surface.
What is the free surface of liquids?
it is because a liquid is bounded by 3sides .thus it has only the upper free surface.
How do plants who don't have a vascular system get water and nutrients?
By absorption through rhizoides and free surface of body cells
What cells has one free surface and lack blood vessels?
epithelial tissue
What is microvilli'?
Tiny projections on the free surface of some epithelial cells; increase surface area for absorption
What is the function of human epitheal cells?
Epithelial cells found on the surface. They cover the and line the free surfaces.
The tissue that always has a free surface exposed to the internal or external environment?
Epithelial tissue

What kind of epithelial tissue is found in the heart?
== Epithelial tissue is located on the very outside of an organ or organism (i.e. skin) or found lining lumen (cavities in hollow organs (i.e. stomach lining). Epithelial tissue always has a free surface (no contact with another cell). Epithelial tissue is also avascular (no blood vessels) and must depend on underlying tissues for the nutrients and oxygen it needs to maintain homeostasis. For this reason, epithelial tissue is usually very thin. Another characteristic of epithelial tissue is that it has little to no intercellular matrix between it's cells. The cells are tightly packed together. Major functions of epithelial tissue include, protection, secretion, and absorption. And as another wiki person ID1342641670 said The epithelial tissue protects the main organ (the heart) from rubbing and damaging the lobes in the heart against the lungs it provides an extra barrier for security and saves the heart from injuries to the upper body around the heart area===
What is free surface?
An epithelium always has on surface where the cells are exposed either to the external environment or to an internal passageway or cavity; this surface is called the free surface of the epithelium.

When epithelial tissue is a single layer its called?
The portion of the cell exposed to the lumen. The layer of plasma membrane on the apical side (side towards the lumen) of the epithelial cells in a body tube or cavity, separated from the basolateral membrane by the zonula occludens.- thefreedictionary.com
