it is because for the diffusion of water and oxygen molecules
They walls are a single layer of squamous epithelial cells.
Capillaries are the smallest blood vessels in the body, consisting of a single layer of endothelial cells. They are where oxygen and nutrients are exchanged with tissues.
Epithelial tissue exists in stratified and single layers.
Simple epithelial cells.
Simple Squamous epithelial cells are found in the lung (alveoli), lining the lumen of blood vessels, and lymphatic vessels, and also in the kidneys.
alveoli
The cheek epithelial cells are flat and irregularly shaped. They are polygonal squamous cells that have a very thin membrane.
Yes it is. Infact, the alveolus is made up of a single layer of epithelial tissue.
The alveoli consist of an epithelial layer and extracellular matrix surrounded by capillaries.
The pericardium is the layer of the heart formed by a single sheet of squamous epithelial cells covering connective tissue. It acts as a protective membrane around the heart and prevents friction as the heart beats.
The alveoli in the lungs are made of a wet wall that is one cell thick with a network of capillaries to facilitate gas exchange.
Resembling squamous epithelial cells means having a flat, scale-like shape similar to the cells found in the outermost layer of the skin or lining of certain organs. These cells are thin and arranged in a single layer, providing a protective barrier.
