Describe the characteristics,location,and function of cuboidal epithelium.

(N/A) $\rightarrow$ This tissue is composed of a single layer of cube-like cells. Each cell possesses a centrally located,spherical nucleus.
$\rightarrow$ The cells of this tissue sometimes have microvilli on the free surface to increase the area for absorption,for example,in the proximal convoluted tubule of the nephron.
$\rightarrow$ Location: This tissue is commonly found in the ducts of glands and the tubular parts of nephrons in the kidneys.
$\rightarrow$ In the ovary and testis,these cells are referred to as germinal epithelium.
$\rightarrow$ Function: These cells participate in processes such as secretion (e.g.,gastric juice and intestinal juice),excretion,and absorption.
