- ‘The excurrent duct for the gills forms generally at the posterior limit of these small plates.’
- ‘Very similar structures, observed on living sponges of the genus Astrosclera, represent excurrent canal systems.’
- ‘Oxygen concentration in the excurrent air was recorded every second (average of 20 consecutive readings) by the oxygen analyzer and computer described in the BMR section above.’
- ‘A separate experiment revealed that the area of the incurrent naris where dye entered the rosette determined where it would exit the excurrent naris.’
- ‘However, there exists no test to define whether these openings are subdermal cavities and part of the incurrent system, or secondary oscula that were part of the excurrent system.’

- ‘Sylleptic branching, the production of new shoots from current buds without an intervening rest period, is common within light-demanding species with an indeterminate growth pattern and results in an excurrent crown form.’
- ‘The basic body form of sponges consists of numerous small incurrent canals called ostia (sing. ostium) and one or more large excurrent opening called oscula (sing. osculum).’
- ‘Oxygen consumption was determined from the rate of air flow into the chamber and the difference between the concentration of oxygen in the incurrent and excurrent air exiting the chamber, per Hill.’
- ‘The oxygen analyzer monitored and averaged the oxygen content of excurrent air every 60 s and downloaded the data to a computer.’
- ‘These skeletal features readily evident in outer part, but in inner part, where numerous excurrent canals occur, structure obscured by recrystallization.’
Early 17th century: from Latin excurrent- ‘running out’, from the verb excurrere.
