Epithelial cells
The flattened cells that fit together like tiles are called squamous cells. They are found in tissues like the skin, lungs, and blood vessels, where their shape allows for efficient gas exchange and barrier protection.
Well, there lots of shapes, but three common forms are cuboidal shaped cells (which are like cubes), squamous cells (which are like cuboidal except flattened), and then there are columnar cells (which are shaped like columns).As for the flattened cells that are important for protection, this is clearly referring to squamous epithelial cells. Every lumen of our bodies has a layer of epithelium surrounding it, partly for protection. The cells of these layers can be a variety of shapes, but squamous is common. Skin, for example, is squamous epithelial tissue. And yes, these cells fit together like tiles, so their shape is very important to the barrier function they serve. Epithelial cells can form different kinds of junctions between each other. One type, called a 'tight junction', causes the cells to bind to each other extremely closely.
Flattened cells, such as squamous epithelial cells, are important in protection because their flat shape helps create a barrier that prevents the entry of pathogens and other harmful substances. They can form tight junctions that reduce the permeability of tissues, aiding in protection against infection and injury. Additionally, their large surface area allows for efficient exchange of gases and nutrients, crucial for maintaining tissue health.
The flattened cells that fit together like tiles are called squamous cells. They are thin and flat, providing a smooth surface for diffusion and protection in tissues such as the skin, blood vessels, and lungs.
Yes, squamous cells are flat and scale-like in shape when they are fully mature. These cells can be found in tissues that line surfaces, such as the skin, mouth, and respiratory tract. Squamous cells are important for providing protection and facilitating the exchange of substances across surfaces.

Cells can have different shapes to serve specific functions. For example, flat cells are well-suited for covering surfaces and allowing for the exchange of materials, while long and elongated cells like muscle cells are ideal for producing movement. Irregularly shaped cells such as dendritic cells have extensions that enhance their ability to capture foreign particles and present them to other immune cells for recognition. Ultimately, cell shape is intricately linked to its function within the organism.
Primary oocyte is surrounded by flattened epithelial cells called follicular cells.
Stratified squamous epithelium
Simple squamous epithelium provides the least protection among epithelial tissues. It is a single layer of flattened cells found in areas where protection is not the primary function, such as air sacs of the lungs and blood vessels.
Microglia
Organs
The portion of the skin that is composed of nonliving cells is the stratum corneum. This outer layer of the epidermis consists of flattened keratinocytes that are no longer viable but provide protection for the underlying layers of the skin.
