porocephalosis, porocephaliasis
Infection with pentastome parasites which involves the occurrence of adults in the lungs of reptiles, but immature forms may be found in a variety of vertebrates, usually encysted in the mesenteries, liver, or other visceral organs.
poroid, poral
A description of mushrooms that form pores rather than gills.
poroma
1. A callosity.
2. A tumor of cells lining the opening of the sweat glands.
poromechanics
A branch of physics and specifically continuum mechanics and acoustics that studies the behavior of fluid-saturated porous media.

A porous medium or a porous material is a solid (often called matrix) permeated by an interconnected network of pores (voids or empty spaces) filled with a fluid (liquid or gas).

poroplastic
Porous and plastic.
porosis
Cavity formation within a tissue.
porosity
1. The fact of being porous; that is, containing small voids (empty spaces) or cavities that can be permeated by water, air, gas, oil, and so on.
2. The ratio of the total amount of void, or empty, space in a material to the overall bulk volume of the material.
porotomy, meatotomy
An incision (surgical procedure) made to enlarge a meatus (an opening or passage, especially one leading to the body surface), as of the urethra or ureter.

The urethra consists of transport tubes leading from the bladder to discharge urine outside the body.

The ureter is either of a pair of thick-walled tubes that carry urine from the kidney to the urinary bladder.

In males, the urethra travels through the penis, and carries semen as well as urine. In females, the urethra is shorter than in the male and emerges above the vaginal opening.

porous
1. Allowing the passage of molecules dissolved in a fluid medium, therefore implying the presence of pores or small openings in a structure.
2. Full of pores; able to admit passage of a liquid.
porous ood
Wood with larger than normal pores and vessels.
porus (s), pori (pl)
A tiny aperture in a structure; a pore.
porus acusticus externus
The outer opening of the external acoustic meatus (body opening).
porus acusticus internus
The opening of the internal acoustic meatus (body opening) into the cranial cavity.
porus gustatorius
The small taste pore openings in the taste buds of the tongue.
porus sudoriferus
The opening of a sweat gland.
