Difference Between Epithelium and Endothelium

Endothelial cells are a specialized type of epithelial cells. The main difference between epithelial and endothelial cells is that epithelial cells line both internal surfaces and external surfaces of the body whereas endothelial cells line the internal surfaces of the components of the circulatory system.

What is the difference between endothelial and epithelial?

Endothelial cells cover the inner surface of the blood vessel, while the epithelial cells cover the inner surface of the internal organs and the outer surface of the human body.

What is the difference between epithelium mesothelium and endothelium?

Mesothelium is originated from mesoderm whereas endothelium is derived from ectoderm and endoderm in the early embryo. In adults, both mesothelium and endothelium are made up of simple squamous epithelium. ... Therefore, mesothelium is the middle covering of the body whereas endothelium is the inner covering.

Is epithelium and epithelium the same?

Epithelial tissues line the outer surfaces of organs and blood vessels throughout the body, as well as the inner surfaces of cavities in many internal organs. An example is the epidermis, the outermost layer of the skin.
...

What is the meaning of endothelium?

Endothelium: A layer of flat cells lining the closed internal spaces of the body such as the inside of blood vessels and lymphatic vessels (that convey the lymph, a milky fluid) and the heart. ... The word "endothelium" is derived from the Greek "endon," within + G. "thele," nipple.

What are the different types of epithelium?

The different types of epithelial tissues are characterized by their cellular shapes and arrangements: squamous, cuboidal, or columnar epithelia. Single cell layers form simple epithelia, whereas stacked cells form stratified epithelia. Very few capillaries penetrate these tissues.

What can damage endothelium?

Endothelial dysfunction is likely to result from endothelial cell injury triggered via a number of different mechanisms, including the following [2]: bacterial or viral infection; oxidative stress through abnormal regulation of reactive oxygen species, hypoxia, turbulent blood flow and shear stress; environmental ...

What is the special type of epithelium found in the bladder?

Unlike the mucosa of other hollow organs, the urinary bladder is lined with transitional epithelial tissue that is able to stretch significantly to accommodate large volumes of urine. The transitional epithelium also provides protection to the underlying tissues from acidic or alkaline urine.

What type of epithelial tissue is endothelium?

Endothelium is a single layer of squamous endothelial cells that line the interior surface of blood vessels, and lymphatic vessels. The endothelium forms an interface between circulating blood or lymph in the lumen and the rest of the vessel wall.

Which type of epithelial tissue is found in the respiratory tract?

Most of the respiratory passageways, from the nasal cavity through the bronchi, are lined by ciliated, pseudostratified columnar epithelium with goblet cells. Bronchioles are lined by simple cuboidal epithelium. (Lung alveoli, in contrast, are lined by very thin simple squamous epithelium.)

What are the 4 functions of epithelial tissue?

Epithelial tissues are widespread throughout the body. They form the covering of all body surfaces, line body cavities and hollow organs, and are the major tissue in glands. They perform a variety of functions that include protection, secretion, absorption, excretion, filtration, diffusion, and sensory reception.

What are the 6 types of epithelial tissue?

Overview and types of epithelial tissue

Where is simple cuboidal epithelium found in the body?

Simple cuboidal epithelium consists of a single layer cells that are as tall as they are wide. The important functions of the simple cuboidal epithelium are secretion and absorption. This epithelial type is found in the small collecting ducts of the kidneys, pancreas, and salivary glands.
