Which of the following is NOT a function of epithelial tissues?
Formation of red blood cells
Epithelial tissue forms a continuous protective layer covering the body surface and lining internal organs, cavities and glands.
Its main functions include protection against injury and infection, absorption of nutrients as in the intestinal lining, and secretion of substances such as enzymes, hormones and mucus in glands.
Formation of red blood cells, called erythropoiesis, is carried out by hemopoietic tissue found in red bone marrow, not by epithelial tissue.
Hence, formation of red blood cells is not a function of epithelial tissues.
