Potting compounds, casing, fibers, and headers are components specifically associated with a dialyzer. A dialyzer is an artificial kidney used in hemodialysis to facilitate the removal of waste products and excess fluid from the blood.

In the context of a dialyzer, potting compounds are used to seal and secure the fibers within the dialyzer casing, ensuring that blood flows through the fibers while being properly filtered. The casing itself is the outer structure that contains the dialyzer's internal components, including the fiber bundles. The fibers, typically made of synthetic materials, are where the actual filtration occurs as blood passes through them. Headers are the parts at the ends of the dialyzer where the blood enters and exits, connecting the dialyzer to the blood tubing.

These components work together to create an effective dialysis process, highlighting their specific relevance to dialyzers rather than to the other options, which are not structured around these specific components.
