Hope it helps uh ☺☺

Answer 2

Answer:

a. Epithelial tissue is protective tissue in animal body.

• It is true.
• Epithelial tissue is involved in protection of many organs and cavities of the body.
• It covers the whole part of body and doesn't not allow the entry of foreign substances inside the body.
• The organs of animal body and the ducts are lined by epithelial tissue to protect them.

Therefore, the statement is true.

b. The lining of blood vessels, lung alveoli and kidney tubules are all made up of epithelial tissue.

• It is true.
• The lining of blood vessels and alveoli of lungs are made of simple squamous epithelium and kidney tubules are made up of cuboidal epithelium. They both are the epithelial cells.

Hence, the statement is true.

c. Epithelial cells have a lot of intercellular spaces.

• It is false statement.
• The epithelial cells are the protective covering of our body.
• They tightly hold each other and hence, do not have intercellular structure.

Thus, it is a false statement.

d. Epithelial layer is permeable layer.

• It is true.
• Epithelial cells allow the transfer of materials along the cells and help in osmoregulation.

Hence, epithelial cells are highly permeable.

e. Epithelial layer does not allow regulation of materials between body and external environment.

• This is false statement.
• Squamous epithelial cells allow some of the materials to transfer between body and external environment.
• For instance: Exchange of Carbon dioxide and oxygen takes place in alveloli of lungs and blood capillaries.

Hence, the statement above is false.
