Kidney Dialysis Process Quiz

A semipermeable membrane that separates blood from the dialysis fluid, allowing specific substances to pass through while preventing others.

A cylindrical device containing a dialysis membrane that filters blood.

The fluid that helps remove waste products from the blood in a dialysis machine. It's designed to mimic the composition of blood plasma.

This pump ensures blood flows steadily through the dialysis system. Without it, the blood wouldn't be cleaned properly.

A device that prevents air bubbles from entering the patient's bloodstream during dialysis. This is vital because air bubbles can be dangerous.

The process of filtering waste products from blood outside the body using a machine, often for people with kidney failure.

The reason why blood is passed through many small channels in the dialyser is to increase surface area for efficient filtration and substance exchange, making the cleaning process more effective.

Air entering the bloodstream is dangerous because it can cause blockages or damage to blood vessels, potentially leading to serious health complications.

Kidney failure occurs when both kidneys stop functioning, requiring urgent medical intervention like dialysis or a kidney transplant.

The dialysis machine uses a selectively permeable membrane, similar to Visking tubing, to remove waste products from the blood while retaining essential nutrients.

The dialysis fluid contains similar concentrations of essential substances like glucose and salts as found in normal blood, ensuring the blood maintains a balanced composition.

Dialysis is a life-sustaining treatment, needing frequent sessions (multiple times per week) to keep the blood clean and prevent accumulation of waste products.

A kidney transplant is the best long-term solution for kidney failure, replacing the damaged kidneys with healthy ones from a donor.

The donor of a kidney transplant is usually a close relative to minimize the chance of the recipient's body rejecting the new organ.

Immunosuppressant drugs are given to recipients of kidney transplants to prevent their bodies from rejecting the new organ.

Passing blood through tubes within the dialysis machine provides a larger surface area, allowing for more efficient removal of waste products from the blood.

Dialysis is often perceived as unpleasant due to its time-consuming nature, requiring several hours of treatment multiple times a week, limiting a patient's daily activities.
