Multiple Choice

How does an artificial kidney machine carry out dialysis in the urinary system?

By using electrical impulses to break down waste products in the blood.

By filtering blood through a semipermeable membrane to remove waste products and excess fluids.

By increasing the blood pressure to force waste products out of the blood.

By directly injecting dialysis fluid into the bloodstream to absorb toxins.

Verified step by step guidance

Understand the function of the kidneys: The kidneys filter waste products and excess fluids from the blood, which are then excreted as urine.

Learn about dialysis: Dialysis is a medical process that replicates the kidney's function when they are not working properly, by removing waste products and excess fluids from the blood.

Explore the mechanism of an artificial kidney machine: The machine uses a semipermeable membrane to filter the blood. This membrane allows waste products and excess fluids to pass through while retaining larger molecules like proteins and blood cells.

Recognize the role of the semipermeable membrane: The semipermeable membrane in the dialysis machine acts as a selective barrier, similar to the glomerular filtration in the kidneys, allowing only certain substances to pass based on size and charge.

Understand the process of blood filtration: Blood is drawn from the body, passed through the dialysis machine where it is filtered, and then returned to the body, effectively removing waste products and excess fluids.
