- Endothelial cells perform a variety of essential functions in the body. One of the primary functions of endothelium is to act as a semi-permeable barrier between body fluids (blood and lymph) and the organs and tissues of the body.

Endothelium Structure [edit]. Endothelium is mesodermal in origin. Both blood and lymphatic capillaries are composed of a single layer of endothelial cells called a monolayer. In straight sections of a blood vessel, vascular endothelial cells typically align and elongate in the direction of fluid flow.t is a thin layer of simple squamous cells called endothelial cells. Endothelial cells in direct contact with blood are called vascular endothelial cells, whereas those in direct contact with lymph are known as lymphatic endothelial cells.

Difference Between Epithelial and Endothelial Cells Endothelial Cells. Endothelial cells are a lining layer of cells or tissue (endothelium), especially the interior of the blood vessels. In fact, the endothelium lines the entire circulatory system including the one and only heart and all types of blood vessels.pithelial and endothelial cells are far too different types of cells forming different types of tissues in animals. The location, form, and function are different in these two types of tissues.

Function of smooth endoplasmic reticulum? The smooth endoplasmic reticulum has functions in several metabolic processes, including synthesis of lipids, metabolism of carbohydrates and calcium concentration, drug detoxification, and attachment of receptors on cell membrane proteins.It is connected to the nuclear envelope.Smooth endoplasmic reticulum is found in a variety of cell types (both animal and plant) and it serves different functions in each. The Smooth ER also contains the enzyme Glucose-6-phosphatase which converts glucose-6-phosphate to glucose, a step in gluconeogenesis.Smooth ER consists of tubules and vesicles that branch forming a network. In some cells there are dilated areas like the sacs of rough endoplasmic reticulum.he Smooth ER also contains the enzyme Glucose-6-phosphatase which converts glucose-6-phosphate to glucose, a step in gluconeogenesis.

- Endothelial Cells Line All Blood Vessels. The largest blood vessels are arteries and veins, which have a thick, tough wall of connective tissue and and many layers of smooth muscle cells (Figure 22-22). The wall is lined by an exceedingly thin single sheet of endothelial cells, the endothelium, separated from the surrounding outer layers by a basal lamina.

Difference Between Epithelial and Endothelial Cells Epithelial Cells. Epithelial cells form the epithelium, which usually lines the surfaces of the body including the most widely spread and the largest organ of the body, skin. Epithelium is one of the four basic types of tissues; others are muscle tissue, nervous tissue, and connective tissue.In addition to the lining of the skin, the epithelial cells line many glands and cavities of the body.pithelial and endothelial cells are far too different types of cells forming different types of tissues in animals. The location, form, and function are different in these two types of tissues.

- Endothelial cells (Endothelium) are often considered specialized epithelial cells which line blood vessels. Epithelial cells are one of the four types of cells from which animal tissues are constructed (epithelial, nervous, muscle, connective).

Cell and Tissue Biology Interspersed between the epithelial cells are goblet cells that secrete mucus, whose function is to protect and lubricate the lining of the intestine. One of several goblet cells visible in this picture is labeled. Goblet cells look like a drinking goblet, with the pedestal or base toward the basal side.

- Endothelium is the simple squamous epithelium that lines the lumen of the cardiovascular system. Cells of this type have three zones: central perinuclear, zone of organelles and peripheral thin part through which exchanges occur.

Microcirculation The endothelium provides a smooth surface for the flow of blood and regulates the movement of water and dissolved materials in the interstitial plasma between the blood and the tissues. The endothelium also produces molecules that discourage the blood from clotting unless there is a leak.lood flows out of the capillaries into the venules, which have little smooth muscle and are 10-200 µm. The blood flows from the venules into the veins. In addition to these blood vessels, the microcirculation also includes lymphatic capillaries and collecting ducts.

Endothelium For the endothelium of the cornea, see corneal endothelium. Endothelium is a type of epithelium that lines the interior surface of blood vessels and lymphatic vessels, forming an interface between circulating blood or lymph in the lumen and the rest of the vessel wall.It is a thin layer of simple squamous cells called endothelial cells.hese cells have unique functions in vascular biology. These functions include fluid filtration, such as in the glomeruli of the kidney, blood vessel tone, hemostasis, neutrophil recruitment, and hormone trafficking. Endothelium of the interior surfaces of the heart chambers is called endocardium.

The Function and Cell Types of Epithelial Tissue 1 Epithelial cells form the thin layer of cells known as the endothelium, which is continuous with the inner tissue lining of organs such as the brain, lungs, skin, and heart. 2  The free surface of epithelial tissue is usually exposed to fluid or the air, while the bottom surface is attached to a basement membrane. For example, the skin is composed of a layer of epithelial tissue (epidermis) that is supported by a layer of connective tissue. 2  It protects the internal structures of the body from damage and dehydration. 3  Epithelial tissue also helps to protect against microorganisms.
