Answer;
-Simple cuboidal
Step-by-step explanation;
-The walls of kidney tubules are formed by simple cuboidal epithelium, which functions in resorbing materials filtered from blood plasma such as nutrients, ions, and water.
-Simple cuboidal epithelium is found in organs that are specialized for secretion, such as salivary glands and thyroid follicles, and those that are specialized for diffusion, such as the kidney tubules.The cells of simple cuboidal epithelium are specialized for diffusion and absorption.
-The cells of this type of tissue can withstand more trauma than simple squamous epithelia and are adapted for diffusion and secretion.
