Multiple Choice

Which two statements best characterize simple squamous epithelial tissue?

It forms the outermost layer of the skin and is highly keratinized.

It is specialized for secretion and absorption in glandular tissue.

It is composed of multiple layers of cube-shaped cells and provides strong protection.

It consists of a single layer of flat cells and allows for rapid diffusion.

Verified step by step guidance

Understand the structure of simple squamous epithelial tissue: It consists of a single layer of flat, thin cells. This structure is specialized for processes like diffusion and filtration due to its minimal barrier.

Recognize the function of simple squamous epithelial tissue: Its thin, flat cells allow for rapid diffusion of gases, nutrients, and waste products, making it ideal for locations like the alveoli in the lungs and the lining of blood vessels (endothelium).

Eliminate incorrect options: The statement 'It forms the outermost layer of the skin and is highly keratinized' refers to stratified squamous epithelium, not simple squamous epithelium. Similarly, 'It is specialized for secretion and absorption in glandular tissue' describes cuboidal or columnar epithelial tissue, not simple squamous.

Analyze the correct characteristics: The statement 'It consists of a single layer of flat cells and allows for rapid diffusion' accurately describes simple squamous epithelial tissue, aligning with its structure and function.

Confirm the answer: Based on the structure and function of simple squamous epithelial tissue, the correct characterization is 'It consists of a single layer of flat cells and allows for rapid diffusion.'
