pericardial cavity
serous
Pleura
A comination of cartillage and synovial fluid resduced the frinction at synovial joints. Cartillagenous and fibrous joints dont really move and so dont need to have friction reduced.
Fluid Friction is friction created by a fluid or gass, and sliding friction practical says it in the name stupid
reduces friction
The visceral membrane is a type of serous membrane, which covers the outer layer of organs (such as the intestines). It secretes small amounts of a serous fluid, which reduces friction between organs and other structures.
Serous membranes line body cavities that do not open directly to the outside, and they cover the organs located in those cavities. Serous membranes are covered by a thin layer of serous fluid that is secreted by the epithelium. Serous fluid lubricates the membrane and reduces friction and abrasion when organs in the thoracic or abdominopelvic cavity move against each other or the cavity wall. Serous membranes have special names given according to their location. For example, the serous membrane that lines the thoracic cavity and covers the lungs is called pleura.
Pericardial Cavity
pericardial cavity
The pericardial fluid
Serous tissues secrete a fluid that lubricates to minimize friction from muscle movement. There are many organs in our body that have serous tissues in it like the heart and the stomach, without the secreted fluid these tissues, these organs will be dry.
serous
The visceral and parietal layers are belong to a type of epithelial membrane called serous membranes. Serous fluid is a fluid between the two layers that helps them slide past each other without causing friction.
Pleura
To enable organs such as the heart and the stomach to slide across cavity walls and each other without friction.
Serous membranes line and enclose several body cavities where they secrete a lubricating fluid which reduces friction from muscle movement.Serous membranes are responsible for secreting serous fluids. Some organs that have serous membranes are the uterus, stomach, pericardium (the area that surrounds the heart), the pleural cavity (the area that surrounds the lungs) and the paritoneal cavity (the cavity that lines the abdominal organs). Without the secretions of the serous membranes, these areas would be dry....can you imagine your lungs sticking to your ribs as you breathe? That would not be good!Hope this helpsA RN in NJ
