Step-by-step explanation:
Glands are made of a type of epithelial tissue called cuboidal epithelial tissue. Epithelial tissue is a tissue that lines surfaces of the body and organs. There are different types of epithelial tissue that are classified by the way the cells are shaped. Cuboidal cells are shaped like cubes. Other types are columnar cells that are shaped like columns, and squamous cells which are flat cells that look like scales. The function of epithelial tissue is to protect the tissue underneath them from trauma and disease. Epithelial tissue also secretes enzymes, hormones, and sweat.
