true.
Thoracic paracentesis is more commonly referred to (at least in the United States) as simply thoracentesis, and it is the draining of fluid from the thoracic (chest) cavity.
There are 2 types of pleura in the thoracic cavity. Visceral pleura which covers the lungs and parietal pleura which covers the inner surface of the thoracic cage. These 2 pleurae form a sac which encases the lungs, the surface tension of the fluid links the lungs and thoracic cavity together aka pleural linkage, which allows the lungs and thorax to operate together as one unit.
The lung is "held" to the thoracic wall by a vacuum or a "potential" space. The thoracic wall has a thin membrane attached to it called the parietal pleura. The lung also has this membrane attached to it but is called the visceral pleura. The two pleura touch each other and slide against each other but are not attached. There is no space between them in the same way there is no space between the sides of a balloon when you suck out the air. If you are stabbed in the chest, an opening is created and air rushes in the hole. The "potential" space becomes an actual space as the lung collapses (a condition called a pneumothorax).
A chylothorax is a condition that results from lymphatic fluid accumulating in the pleural cavity. Its cause is usually leakage from the thoracic duct or one of the main lymphatic vessels that drain to it. The most common causes are lymphoma and trauma caused by thoracic surgery.11. http://en.wikipedia.org/wiki/Chylothorax
A blastocoele is the fluid-filled cavity in the blastula.
If there is brown fluid in the chest cavity, it could be blood or pus. This can become dangerous if there is an abundance of fluid.
Serous fluid in the peritoneal cavity provides lubrication for the organs.
No, ascites is a condition in which fluid collects in the abdominal cavity.
Fluid is often found in both cavities, and fluid from one cavity can find its way into the other.
A cyst is an accumulation of fluid in a saclike cavity. A hydrocele is a collection of fluid in the scrotum.
r answer here... cavity are the insides of body organes
fluid traped in cavity of ballvave is relived through cavity vent, care is taken pressure of fluid traped in cavity should not increse than upstream pressure of the valve.
