What is the fluid secreted by the specialized membranes that line the body cavities?
The fluid is called serous fluid, and it acts as a lubricant to reduce friction between organs in body cavities. It is produced by serous membranes, such as the pleura in the chest cavity, pericardium around the heart, and peritoneum in the abdominal cavity.
What would happen if you damage your serous membranes?
Damaging your serous membranes can lead to inflammation and potential infection. This can cause pain, swelling, and impaired function of the affected organ or area. It may also lead to the accumulation of fluid in the cavity lined by the serous membrane.
Where does serous fluid come from?
Serous fluid is a clear, watery substance that is secreted by serous membranes, which are thin, double-layered membranes that line body cavities and internal organs. These membranes produce serous fluid to lubricate and reduce friction between tissues during movement.
What is the difference between the serosa and adventitia?
Serosa is a serous membrane that secretes serous fluid, adventitia does not.
What is the serous fluid reduces surface tension?
Surfactants, which are molecules that lower surface tension, can be found in serous fluid. These molecules help prevent alveoli in the lungs from collapsing by reducing the surface tension of the fluid lining the alveoli.
