Understanding Epithelial Cells
Epithelial cells play a vital role in protecting the body from harmful viruses by forming a defensive barrier. While they primarily cover the outer layer of the skin, these cells can also be present on the linings of blood vessels, internal organs, and the digestive tract. Presence of a few epithelial cells in urine is considered normal, but an excess amount may indicate an underlying health issue.
Understanding the Various Varieties of Epithelial Cells
Epithelial cells, which are one of the building blocks of the human body, come in various forms and serve different functions. These specialized cells line the surfaces of organs, blood vessels, and body cavities, forming a protective barrier. Here, we explore the different types of epithelial cells and their respective roles.
