Serous fluid originates from serous glands, with secretions enriched with proteins and water,serous fluid may also originate from mixed glands, which contain both mucous and serous cells. Serous fluid is a synonym for effusion fluids from various body cavities.
A serous membrane (also referred to as a serosa) is one of the thin membranes that cover the walls and organs in the thoracic and abdominopelvic cavities. The parietal layers of the membranes line the walls of the body cavity (pariet-refers to a cavity wall). Each serous membrane is composed of a secretory epithelial layer and a connective tissue layer underneath. 1  The epithelial layer, known as mesothelium, consists of a single layer of avascular flat nucleated cells (simple squamous epithelium) which produce the lubricating serous fluid. A serous membrane is a thin membrane that helps body parts move more easily and reduces friction between them. Also known as serosa, these membranes are found throughout the body, usually surrounding organs. There are several medical conditions associated with the serous membane, some of which can be life threatening. Serous membranes are found in the abdominal and pelvic areas around the stomach and reproductive organs. Serous membranes can be found in the testicles. The serous membrane around the heart is called the pericardium. Serosa are found throughout the human body, usually around organs like the stomach. Related Problems. Problems with a serous membrane can be related to the serous fluid or to the two tissue layers. An overproduction of fluid can cause serious problems, especially if enough fluid is produced to put pressure on a person's organs. Serous membranes are found in the abdominal and pelvic areas around the stomach and reproductive organs. Serous membranes can be found in the testicles. The serous membrane around the heart is called the pericardium. Serosa are found throughout the human body, usually around organs like the stomach. Serous fluid originates from serous glands, with secretions enriched with proteins and water. Serous fluid may also originate from mixed glands, which contain both mucous and serous cells. A common trait of serous fluids is their role in assisting digestion, excretion, and respiration. In medical fields, especially cytopathology, serous fluid is a synonym for effusion fluids from various body cavities. There are many causes of effusions which include involvement of the cavity by cancer. Cytopathology evaluation is recommended to evaluate the causes of effusions in these cavities. Another type of serous fluid is secreted by the serous membranes (or serosa), two-layered membranes which line the body cavities. Serous membrane fluid collects on microvilli on the outer layer and acts as a lubricant and reduces friction from muscle movement. This can be seen in the lungs. In anatomy, serous membrane (or serosa) is a smooth membrane consisting of two layers of epithelial cells (as membranes), which secrete serous fluid. Each serous membrane is composed of a secretory epithelial layer and a connective tissue layer underneath. 1  The epithelial layer, known as mesothelium, consists of a single layer of avascular flat nucleated cells (simple squamous epithelium) which produce the lubricating serous fluid. a fluid that has the characteristics of serum. Fluid secreted by serous membranes that reduces friction in the serous cavities (pleural, pericardial, and peritoneal).  The inner layer covers organs in bodily cavities and is called the visceral membrane; this inner layer of epithelial cells is followed by a connective tissue; after the connective tissue is the second layer of epithelial cells of the serous membrane called the parietal layer. The Latin anatomical name is tunica serosa. Each serous membrane is composed of a secretory epithelial layer and a connective tissue layer underneath. 1  The epithelial layer, known as mesothelium, consists of a single layer of avascular flat nucleated cells (simple squamous epithelium) which produce the lubricating serous fluid. Central serous retinopathy (CSR), also known as central serous chorioretinopathy (CSC), is an eye disease which causes visual impairment, often temporary, usually in one eye. When the disorder is active it is characterized by leakage of fluid under the retina that has a propensity to accumulate under the central macula.
