identify the primary function(s) of simple squamous epithelium cells.

select all that apply.

filtration
secretion
protection
absorption
diffusion

Explanation:

Analyze tissue structure

Simple squamous epithelium consists of a single layer of flat, scale-like cells. This extremely thin barrier is optimized for rapid transport rather than physical protection. We apply Epithelial Tissue Characteristics to relate this thin structure to its physiological roles.

Evaluate transport functions

Because the layer is so thin, substances can easily pass through it. This makes simple squamous epithelium ideal for Diffusion (such as gas exchange in the alveoli of the lungs) and Filtration (such as blood filtration in the kidneys).

Evaluate other functions

Using Epithelial Tissue Classification, we know that thicker, multi-layered tissues (like stratified squamous) provide protection, while taller cells (like cuboidal or columnar) are specialized for absorption and secretion. Thus, protection, absorption, and secretion are not primary functions of simple squamous epithelium.

Answer:

• Filtration (Correct answer)
• Secretion
• Protection
• Absorption
• Diffusion (Correct answer)
