angle

the space or figure formed by two diverging lines, measured as the number of degrees one would have to be moved to coincide with the other.

that formed by the junction of the shadows of the heart and diaphragm in radiographs.

costovertebral angle

the angle formed on either side of the vertebral column between the last rib and the lumbar vertebrae.

filtration

passage through a filter or through a material that prevents passage of certain molecules, e.g. capillary wall, blood-brain barrier, radiographic grid.

filtration angle

developmental or acquired distortion of this part of the eye is the common cause of glaucoma. It is the space bounded by the sclera externally, the ciliary muscle posteriorly, the root of the iris medially and the anterior chamber of the eye anteriorly. Within the space is the filtering mechanism, a mass of anastomosing mesodermal spindle cells with many perforations between them.

filtration barrier

the physiological function which limits the passage of small molecules through the renal corpuscle.

glomerular filtration

the process by which glomerular filtrate is formed, involving the balance of pressures across the walls of the glomerular capillaries.

inherent filtration

attenuation of the primary x-ray beam as a result of its passage out of the x-ray tube through the insulating medium and tube window.

filtration membrane

the membrane which stretches across the filtration slits in the renal corpuscle.

filtration pressure

the net driving force which pushes fluid into tissue spaces and out of vascular sites; the net result between capillary osmotic pressure and intravascular hydrostatic pressure.

filtration slits

openings in the glomerular corpuscle which are part of the filtration process in the renal glomerulus.
