Dialysis: How Does It Work?

Course overview

Healthy kidneys eliminate waste and excess water from the blood, but when kidneys stop functioning because of illness or injury, dialysis offers an artificial alternative to ensure individuals stay healthy. Depending on the specific illness or injury, dialysis may be a chronic need or may only be required temporarily until a person's kidney is healthy enough to function. A closer look at how dialysis functions within the body is discussed. No Test Required!
