1. A dialysis treatment apparatus comprising:
an elongate housing defining a longitudinal axis and including first and second end caps at opposite ends of the housing; and
a plurality of hollow membranous fibers within an interior of the housing between the first and second end caps, each hollow membranous fiber defining a lumen; and
a pump rotor in the first end cap,
wherein the dialysis treatment apparatus defines a blood flow path that extends through the first end cap, then through the lumens of the hollow membranous fibers, and then through the second end cap, and
wherein the blood flow path: (i) enters the first end cap transverse to the longitudinal axis, (ii) then transitions parallel to the longitudinal axis, (iii) then enters the pump rotor, and (iv) then, after exiting the pump rotor, extends toward the hollow membranous fibers.
