Why don't libraries smell like bookstores? These highly vascularized bulbous structures are made of a single layer of squamous cells and are surrounded by an intricate network of capillaries. The liquid that is obtained at the start of the nephron is called the glomerular filtrate and through a series of secretion, absorption and reabsorption events, urine is eventually formed, and expelled from the body. Secretion: Various glands made up of epithelial cells secrete hormones, enzymes, saliva, mucus, sweat, etc. Simple squamous epithelia are tissues formed from one layer of squamous cells that line surfaces.

In this image, capillaries are colored red with the Bowman’s capsule surrounding them. Four types of the simple epithelium are simple squamous, simple cuboidal, simple columnar, and pseudostratified epithelium. Generally, this type of epithelium is found inside the body probably due to the fragile nature and forms the lining of the body cavities, blood and lymph vessels, heart and respiratory system.. There is no matrix in this tissue. They also play a role in diffusion, osmosis and filtration. nuclei and sparse cytoplasm. Capillaries are also made of a single layer of squamous cells and this allows for gas exchange between the alveoli and blood vessels. Type 1 alveoli cells cover 95 percent of the alveolar surface and constitute the air-blood barrier. A stratified squamous epithelium is quite thick, with squamous cells on the surface coating deeper layers of higher cells.
