The act of pouring out; as, effusion of water, of blood, of grace, of words, and the like.
That which is poured out, literally or figuratively.
The escape of a fluid out of its natural vessel, either by rupture of the vessel, or by exudation through its walls. It may pass into the substance of an organ, or issue upon a free surface.
The liquid escaping or exuded.
effuse. Compare with diffusion and diffraction. Gas molecules in a container escape from tiny pinholes into a vacuum with the same average velocity they have inside the container. They also move in straight-line trajectories through the pinhole.
Fluid escaping into a body space or tissue (e.g., pleural effusion).
accumulation of fluid in the middle ear
Collection of fluid in tissue or in a body cavity, such as in the chest (pleural effusion).
Build-up of fluid in a part of the body, particularly a joint.
escape of fluid from the lymphatics or blood vessels into a cavity or into tissues
collection of fluid in the middle ear behind the TM.
abnormal collection of fluid. a pericardial effusion (fluid around the heart) or pleural effusions (fluid around one or both lungs) can be signs of heart failure of the fetus (hydrops). Other signs of abnormal fluid accumulation are ascites and edema.
Escape of fluid into a pad, as the pleural cavity, such as hemothorax (blood), pneumothorax (air), etc.
Accumulation of fluid, or the fluid itself, in various spaces in the body. Commonly found in the knee following injury.
a process that occurs when a gas escapes through a tiny hole in its container. (see diffusion, Graham's law of effusion)
accumulation of fluid in body cavities or between tissues.
the abnormal escape of a fluid from anatomical vessels by rupture or exudation; also free fluid within a joint or cavity.
The escape of fluid into a part or tissue as an exudation
The process by which a gas escapes through a pinhole into a vacuum.
a collection of fluid OUTSIDE the lung itself, but INSIDE the chest cavity
when gas molecules escape from their container through tiny holes in the container.
Fluid that has seeped into a body cavity, such as the middle ear.
1. The escape of fluid from the blood vessels or lymphatics into the tissues or a cavity. 2. A collection of the fluid effused. joint effusion increased fluid in synovial cavity of a joint.
Accumulation of fluid in various spaces of the body, or knee itself which is a frequent byproduct of injury.
A collection of fluid inside a body cavity, such as around the lungs, (pleural), intestines (peritoneal) or heart (pericardial).
An exudate in a serous cavity (pericardial, pleural or peritoneal).
Collection or pooling of fluids in the joint capsule
A collection of fluid in a body cavity, usually between two adjoining tissues. For example, a pleural effusion is the collection of fluid between two layers of the pleura (the lung's covering).
Accumulation of fluid, in various spaces in the body, or the knee itself. Commonly, the knee has an effusion after an injury.
escape of fluid into a body part; edema
A collection of fluid in a body cavity, usually between two adjoining tissues. For example, a pleural effusion is in the chest and peritoneal effusion is in the abdomen.
The accumulation of fluid in a joint.
a collection of fluid generally containing a bacterial culture.
Fluid escaping into a body cavity or tissue.
fluid build up, usually behind the eardrum
Too much fluid, an outpouring of fluid. A hemorrhagic effusion is one that has blood within the fluid. A pericardial effusion is an outpouring of fluid within the fibrous sac (the pericardium) that surrounds the heart. The lungs are covered by two-layered membranes which are called the pleura. A pleural effusion involves the presence of an excessive amount of pleural fluid (between the two layers of the pleural membranes). The term "effusion" comes from the Latin "effusio" meaning a pouring out.
Excess fluid inside a body cavity such as the abdomen or chest.
Fluid accumulation (i.e. pericardial effusion is a fluid accumulation in the heart that surrounds the heart).
the escape of fluid into a part such as the pleural space around the lungs. Examples would be hemothorax (blood in the space) and pneumothorax (air in the space).
Accumulation of fluid, or the fluid itself, in various spaces in the body. Commonly, the knee has an effusion after an injury.
