1. A dialysis system comprising:
a dialysis machine including a blood pump actuator, a dialysate pump actuator, a blood valve actuator, a dialysate valve actuator, and a sorbent device; and a disposable cassette operable with the dialysis machine, the disposable cassette including:
(i) a housing,(ii) a dialysate pump portion of the housing configured to operate with the dialysate pump actuator,(iii) a blood valve portion of the housing configured to operate with the blood valve actuator,(iv) a dialysate valve portion of the housing configured to operate with the dialysate valve actuator,(v) at least one dialyzer in fluid communication with the housing, the at least one dialyzer including a dialysate inlet and a dialysate outlet,(vi) a first dialysate connection connected to and extending externally from a dedicated dialyzer inlet port of the housing to the dialyzer inlet, the first dialysate connection in fluid communication with the sorbent device while the disposable cassette is mated for operation with the dialysis machine,(vii) a second dialysate connection connected to and extending externally from a dedicated dialyzer outlet port of the housing to the dialyzer outlet, the second dialysate connection in fluid communication with the sorbent device while the disposable cassette is mated for operation with the dialysis machine, and(viii) arterial and venous blood lines for connecting to a patient, the arterial line connected to and extending externally from a dedicated arterial port of the housing, the venous line connected to and extending externally from a dedicated venous port of the housing.
