GENERAL HISTOLOGY

Detailed explanation-1: -Epithelial tissue is one of the four main types of body tissue found in your organs and covers internal and external surfaces in your body.

Detailed explanation-4: -The epithelial tissue present on the inner lining of kidney tubules is cuboidal epithelium. No worries!

Detailed explanation-5: -Epithelial tissues provide the body’s first line of protection from physical, chemical, and biological damage. The cells of an epithelium act as gatekeepers of the body, controlling permeability by allowing selective transfer of materials across its surface. All substances that enter the body must cross an epithelium.
