PPT-The Epithelium Tissues

Glandular epithelium Prepared by Reem Aldossari a gland may consist of one cell or a group of cells highly specialized to secrete substances into ducts onto surfaces or into the blood.

In the late 1600’s British born Robert Hooke coined. the term "cell" to describe the basic unit of life.. Where did the term cell come from?. In 1665 Robert Hooke inspected thin slices of cork and found that they consisted of millions of small, “irregular units”. BIO 137: Anatomy & . Physiology . I. Tissues.
