Metric Options: Counts1 Year3 YearSelecting the 1-year or 3-year option will change the metrics count to percentiles, illustrating how an article or review compares to other articles or reviews within the selected time period in the same journal. Selecting the 1-year option compares the metrics against other articles/reviews that were also published in the same calendar year. Selecting the 3-year option compares the metrics against other articles/reviews that were also published in the same calendar year plus the two years prior.
Example: if you select the 1-year option for an article published in 2019 and a metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019. If you select the 3-year option for the same article published in 2019 and the metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019, 2018 and 2017.

Article Description
The Excretory organ (H-system) of Ascaris lumbricoides has been investigated electronmicroscopically. In adult animals this single-cell-organ embedded in the lateral lines extends from the nerve ring to approximately the middle of the body. In the second quarter of the body it lacks a continuous canal lumen, and it seems to be degenerated. In all of the other regions (except the stem leading to the excretory pore) it consists of two zones. The inner zone lining the canal lumen contains several extraplasmatic spaces; at least those placed the farthest inside communicate with the canal lumen. The outer cell membrane shows many infoldings, some of which extend deeply into the cytoplasm. The tissue of the lateral line adjacent to the canal system contains very many intercellular spaces which build a coherent intracellular "rainage"-system. Experiments have been performed in order to localize the ATPase activity histochemically. Possible mechanisms for the forming of the excretory fluid are discussed under consideration of physiological results already published. © 1971 Springer-Verlag.
