Which of the following is a type of dialysis?

Hemodialysis is a type of dialysis that involves the process of removing wastes and excess fluid from the blood when the kidneys are not able to perform this function effectively. During hemodialysis, blood is drawn from the body, cleaned through a dialyzer (artificial kidney), and then returned to the body. This process helps maintain the balance of electrolytes and removes toxins, which is crucial in patients with kidney failure.

In the context of the other terms, continuous renal replacement therapy is an alternative form of dialysis typically used in critically ill patients who require slower, more controlled treatment. Laparoscopic dialysis is not a standard term associated with dialysis modalities; instead, it may refer to procedures involving a laparoscope, which does not pertain to the dialysis process itself. Conventional dialysis can be a vague term and may refer to dialysis techniques broadly, but it does not specifically denote a recognized method like hemodialysis.
