| The velocity of the excurrent stream through the osculum may be several hundred times that at the level of the choanocytes. |
|
| Oxygen concentration in the excurrent air was recorded every second by the oxygen analyzer and computer described in the BMR section above. |
|
| That is, sperm are created, concentrated and sent out the excurrent openings, sometimes in masses so dense that the sponges appear to be smoking. |
|
| The opercular is more often made up of one or more immobile bones which channel the excurrent from gills with individual covers. |
|
| The oxygen analyzer monitored and averaged the oxygen content of excurrent air every 60 s and downloaded the data to a computer. |
|
| 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. |
|
| Colonies with greater than 12 individuals across, may have fixed water excurrent chimneys reflected in the skeleton. |
|
| The basic body form of sponges consists of numerous small incurrent canals called ostia and one or more large excurrent opening called oscula. |
|
| Trabs rise upward parallel to or slightly oblique to excurrent canals and form regular ladder-like structure. |
|
| Most conifers and a few hardwoods, such as sweetgum and tuliptree, have excurrent forms. |
|
| The siphons are completely fused with an internal septum between the incurrent siphon and the excurrent siphon. |
|
| These skeletal features readily evident in outer part, but in inner part, where numerous excurrent canals occur, structure obscured by recrystallization. |
|
| Concurrent with this, the entire pectinirhomb becomes greatly protuberant along a large, thinwalled ridge spanning the incurrent and excurrent half rhombs. |
|
| A separate experiment revealed that the area of the incurrent naris where dye entered the rosette determined where it would exit the excurrent naris. |
|
| The male reproductive tract is consisted of the testis and excurrent ducts. |
|
| Water is drawn through the incurrent siphon into the infrabranchial chamber, filtered through the gills into the suprabranchial chamber and is expelled through the excurrent siphon. |
|
| In tadpoles the spiracle is the excurrent opening from the gill chamber. |
|
| Thus wave energy moves the water shoreward until it reaches an excurrent drainage channel slightly deeper than the culture channels, and water circulation is ensured. |
|
| This species of tree is recognized by the excurrent veins in its leaves. |
|
|
|
| The initial increase in filtration is a response to greater advection of water pockets of depleted seston emanating from the excurrent siphon of the clam. |
|
| The excurrent nasal openings are on the dorsal side of the skull roof. |
|
| In this project, oak species had lower in-woods utilization rates than species with a more excurrent branching pattern, such as pine species and yellow poplar. |
|
| Inflammatory conditions of the male excurrent ductal system. |
