Study Notes
Epithelial Tissues
- Classified into three types based on cell shape: squamous, columnar, and cuboidal
- Squamous epithelium: cells appear flat, hexagonal or irregular in shape, line the blood vessels, lungs, heart, oesophagus, and epidermis of the skin
- Columnar epithelium: cells appear column-like, longer than wide, with nucleus at the base, found in stomach, intestines, and pharynx
- Cuboidal epithelium: cells appear square in shape, with centrally located nucleus, found in thyroid gland, kidney tubules, salivary glands, pancreas, and liver
Functions of Epithelial Tissues
- Protective tissue, covering outer surface of the body and lining internal organs
- Protects the body and organs from injury, germs, and more
- Specialized to secrete enzymes in salivary and gastric glands for digestion
- Certain epithelial cells absorb nutrients from digested food
- Also helps remove waste products from the body in sweat glands and kidneys
Animal Tissues
- Classified into four basic types: epithelial, muscular, nervous, and connective tissues
- Each type has distinct characteristics based on cell type, intercellular material, and function
