Explanation:
Animal Tissues
Animals move around in search of food, mates and shelter.
Most of the tissues they contain are living.
The structural organisation of organs and organ systems is far more specialised and localised in animals than in plants.
Types of Animal Tissues:
Animal tissues are classified into four types based on the functions they perform:
(i) Epithelial
(ii) Connective
(iii) Muscular
(iv) Nervous
(i) Epithelial tissues
They form the covering of the external surfaces, internal cavities and organs of the animal body.
Epithelial tissue cells are tightly packed and form a continuous sheet.
The skin, the lining of the mouth, the lining of blood vessels, lung alveoli and kidney tubules are all made of epithelial tissue.
Functions of Epithelial Tissue:
(i) Epithelitum covers most organs and cavities within the body.
(ii) It also forms a barrier to keep different body systems separate.
(iii) The permeability of the cells of various epithelia play an important role in regulating the exchange of materials between the body and the external environment.
