A student calculated the average surface area-to-volume ratio of four different types of human epithelial cells. The results are shown in the table below. Based on the data, which type of cell would be best suited for lining the alveoli of the lungs, where diffusion of carbon dioxide and oxygen must occur very rapidly? Simple squamous cells Simple cuboidal cells Simple columnar cells Simple spherical cells

There is no data attached to this question, however, the question can be answered based on general understanding of epithelium tissues.

The answer is Simple squamous cells

Explanation:

Epithelial tissues are those tissues that line or cover the surfaces of walls or structures. However, based on the one cell layer and their shape, which defines their function, epithelial tissues are classified into the following:

- Simple squamous

- Simple cuboidal

- Simple columnar

All the above have one cell layer. This question involves a student that calculated the average surface area-to-volume ratio of four different types of human epithelial cells. Based on the question, SIMPLE SQUAMOUS CELLS would be best suited for lining the alveoli of the lungs, where diffusion of carbon dioxide and oxygen must occur very rapidly.

This is because the simple squamous cells, which are shaped like the scales of a fish, are thin-walled flat cells. Hence, they are found or adapted to parts where where diffusion or filtration takes place e.g alveoli of the lungs
