Where in the body do serous membranes occur?
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.
Why is the lubrication a serous membrane provides important?
reduces friction
Stability of an animal cell plasma membrane is enhanced by?
cholesterol molecules because at warm temperatures, cholesterol reduces membrane fluidity by restraining the movement of phospholipids. At low temperatures, cholesterol hinders solidification of the membrane because it prevents the close packing of phospholipids.
What type of hormone reduces inflammation?
growth hormone
Where is the retro perineal cavity located?
The retroperitoneal cavity is located immediately posterior to the abdominal cavity (behind). It contains the kidneys (and so also the adrenal glands), the pancreas, and the abdominal aorta and vena cava. The walls of the abdominal cavity are covered with a serous membrane, called the peritoneum, as are most internal organs. The fluid in the membrane protects these structures and reduces friction between the organs and the cavity walls as well as between the organs themselves. The retroperitoneal space is separated from the peritoneal space by this layer of membrane covering the anterior organs e.g. liver, stomach, intestines. Both spaces are within the abdominal cavity.
Which molecule in animal plasma membranes stiffens and strengthens the membrane?
Methionine, a sulfur-containing amino acid, is an intermediary that helps strengthen cell membranes. The infamous cholesterol that we're often advised to avoid also helps maintain the integrity of cell membranes (and to a lesser degree, the integrity of the membranes of organelles inside the cell). The cell's plasma membrane is considered a fluid mosaic where the lipid molecules in the bilayer move about in the membrane. However, cell membranes may experience transitions which make their molecules more gel-like or nearly solid.
What is the membrane that surrounds each lung and reduces the friction of breathing?
They are called pleura. There are 2 membranes, the visceral which is the outer slippery covering, and the parietal which is the inner covering, with a cavity in between them called the pleural cavity

What are the advantages of the membrane cell over the mercury and diaphragm cell?
It reduces energy consumption
What is the visceral membrane?
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.
What forms a thin serous membrane a single layer of flattened cells?
The serous membranes are formed by mesothelium cells. This layer secretes a liquid that reduces friction in cavities such as the pleura, peritoneum, and pericardium.
Why is the heart anchored to the diaphragm and what is the function of this anchoring?
The heart is anchored to the diaphragm in order to keep it in place. The diaphragm also reduces friction to the outer membranes of the heart.

Our chicken eggs are almost ready to hatch some have one egg has a large hole in it that you can see a chicken with feathers in but also bloody membrane will it live?
Interfering with that membrane is what reduces hatch with most novice breeders. The temptation to "help" is very strong but that membrane will keep bleeding if too much tearing takes place. The actions of the chick from the inside trigger the blood to stop flowing as there are actually two membranes, the inner and outer to deal with. Once the first hole is made in the shell and the humidity is right, the chick will get out in most cases, stopping to rest if the shell is exceptionally tough.
What is the function of serous membranes?
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
What is the lining of the lungs?
The parietal pleura.Pleura is the outer covering of LungsThe pleurae are the membranes covering the lungs.The membrane is called the pleura, which is named the parietal pleura for the portion of the membrane covering the inner chest wall and the visceral pleura for the portion of the membrane covering the lung. The potential space between the visceral and parietal pleurae is called the pleural cavity.its called pleural membrane surrounding the lungs n also contain pleural fluid reduces friction during breathing
