plays a role in the secretion of – cerebrospinal fluid and the hormones, ependyma in the brain, thyroid hormones
Absorption – proximal convoluted tubules and distal convoluted tubules in the kidneys
Simple Squamous Epithelium – These cells appear flat and have a single layer. Its function include selective diffusion of materials which helps in the filtration, absorption and secretion of substances. This type of epithelium is usually found in the cavities of the body including the pericardial, pleural, and peritoneal cavities. Blood vessels also have this tissue. Furthermore, it is also found in the glomeruli of the kidney and alveoli in the respiratory tract.
Ciliated Columnar Epithelium – it contains oval nucleus and a more elongated shape of the cell. It also contains cilia in its outer surface which are short hair-like projections. This type of epithelium is usually seen in the trachea and upper respiratory tract. It is also found in the lining of the fallopian tubes. It propels the mucus and other substances for the clearing of the respiratory tract and other parts of the body where they are present.
