0 a unit for measuring the flow of light -- lumen
1 a small space inside a plant cell -- światło, wnętrze
2 a hollow area inside a body part, for example inside an artery (= tube that carries blood) -- światło
Washings from the lumen of the gut were passed through a sieve (154 mm mesh size) to recover even the smallest parasites.
Indentations in the repaired region leave a somewhat tortuous lumen.
The apical plasma membrane of the rachis is elevated to form numerous microvilli-like projections into the lumen.
The apical plasma membrane extends into the lumen in microvilli-like projections.
The thicker posterior end extends into the caecal lumen to facilitate mating and oviposition.
The gradient in muscle tension created along the intestine (increased in jejunum and decreased in ileum) may promote propulsion of worms in the lumen.
Exposures to high densities of cercariae could lead to encystment in other sites such as the kidney lumen or pericardial cavity.
Although the lumen is not significantly narrowed, localized peaks of velocity, up to 2 m/sec were found close to the two indented regions.
