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, with the pleural cavity. Pericardial fluid is a serous fluid secreted by the serous layer of the pericardium into the pericardial cavity. The pericardium consists of two layers, an ...
The serous membrane (or serosa) is a smooth tissue membrane of mesothelium lining the contents and inner walls of body cavities, which secrete serous fluid to allow lubricated sliding movements between opposing surfaces. The serous membrane that covers internal organs is called visceral, while the one that covers the cavity wall is called parietal.
Ascites (/ ə ˈ s aɪ t i z /; [5] Greek: ἀσκός, romanized: askos, meaning "bag" or "sac" [6]) is the abnormal build-up of fluid in the abdomen. [1] Technically, it is more than 25 ml of fluid in the peritoneal cavity, although volumes greater than one liter may occur. [4]
The differently lined spaces contain different types of fluid. In the meninges for example the fluid is cerebrospinal fluid; in the abdominal cavity the fluid contained in the peritoneum is a serous fluid. In amniotes and some invertebrates the peritoneum lines their largest body cavity called the coelom.
A hydrocele is an accumulation of serous fluid in a body cavity.A hydrocele testis, the most common form of hydrocele, is the accumulation of fluids around a testicle.It is often caused by fluid collecting within a layer wrapped around the testicle, called the tunica vaginalis, which is derived from peritoneum.
A small amount of serous pleural fluid is maintained in the pleural cavity to enable lubrication between the membranes, and also to create a pressure gradient. [ 1 ] The serous membrane that covers the surface of the lung is the visceral pleura and is separated from the outer membrane, the parietal pleura , by just the film of pleural fluid in ...
A small amount of fluid, called transcellular fluid, does exist normally in such spaces. For example, the aqueous humor, the vitreous humor, the cerebrospinal fluid, the serous fluid produced by the serous membranes, and the synovial fluid produced by the synovial membranes are all transcellular fluids. They are all very important, yet there is ...
Peritoneal fluid is a serous fluid made by the peritoneum in the abdominal cavity which lubricates the surface of tissue that lines the abdominal wall and pelvic cavity. It covers most of the organs in the abdomen. An increased volume of peritoneal fluid is called ascites. Sampling of peritoneal fluid is generally performed by paracentesis.
