GENERAL HISTOLOGY

Detailed explanation-1: -A hollow fiber dialyzer bundle comprises 7–17 x 103 semipermeable hollow fibers that allow solute and fluid transfer between blood and dialysate. Typical fibers have an internal diameter of 180–200 microns and wall thickness of 30–40 microns, yielding 1.0–2.5 m2 of surface area.

Detailed explanation-2: -Conclusions: Hemodialysis using protein-leaking dialyzers might reduce mortality rates. Furthermore, type V dialyzers are superior to type IV dialyzers in hemodialysis patients.

Detailed explanation-3: -Dialyzers are divided into tube type, flat type, and hollow fiber type.

Detailed explanation-4: -Blood flows through the fibers while dialysate flows outside the fibers, typically in a countercurrent fashion. Hollow-fiber dialyzers are easy to use and provide low blood flow resistance, excellent mass transfer, low compliance, and controllable UF.
