The outer layer of skin is formed by epithelial tissue. The correct option is D.
What is epithelial tissue?Epithelial tissue is a type of tissue that lines internal organs and cavities, creates glands, and covers body surfaces.
Epithelial tissue is what makes up the skin's epidermis, or outer layer. The stratified squamous epithelial cells that make up the majority of the epidermis act as a barrier against microbial, chemical, and physical harm.
The basal layer of the epidermis continuously sheds its squamous epithelial cells, which are then replaced by fresh ones.
The dermis, which is formed of connective tissue and lies beneath the epidermis, supports and nourishes the epidermis.
The epidermis and dermis come together to form the skin, which is the biggest organ in the body and has a number of functions, including protection, temperature regulation, and sensory perception.
Thus, the correct option is D.
