Question

Inner lining of the blood vessel is composed of
(a) Pseudostratified epithelium
(b) Simple cuboidal epithelium
(c) Simple squamous epithelium
(d) Ciliated columnar epithelium

Answer 1

Hint: It is a single layer of flat cells that is often permeable and has a larger surface area. The blood vessels transport blood cells, nutrients, and oxygen to the tissues of the body.

Complete answer: The inner lining of the blood vessels and lymphatic vessels is composed of simple squamous epithelium. It is the thinnest layer made up of a layer of flat cells. These cells have lumen on one side and the basement on the membrane of the other side. They are present in alveoli, capillaries, glomeruli, and other body tissues, where instant diffusion is required.
It's glued by a polysaccharide intercellular matrix, surrounded by a skinny layer of subendothelial connective tissue. It's interlaced with a variety of circularly arranged elastic bands called the interior elastic lamina. A thin membrane of elastic fibers within the tunica intima runs parallel to the vessel.
A simple squamous epithelium may be a single layer of flat cells in touch with the basal lamina (one of the 2 layers of the basement membrane) of the epithelium.
This sort of epithelium is usually permeable and present where small molecules get to pass easily through membranes via filtration or diffusion.
Cells are flat with flattened and oblong nuclei. It's also called pavement epithelium due to its tile-like appearance.This epithelium is related to filtration and diffusion. This tissue is extremely thin and forms a fragile lining. It offers little or no protection.

So, the correct answer is ‘simple squamous epithelium’.
Note: Generally, arteries and arterioles transport oxygenated blood from the lungs to the body and its organs, and veins and venules transport deoxygenated blood from the body to the lungs. The common disease of the blood vessels in hypertension. This is often caused by a rise within the pressure of the blood flowing through the vessels.
