What waste product is produced by the liver from the breakdown of excess amino acids?

Sweat

Bile

Urea

Carbon dioxide

The liver is vital for excretion in humans. Which of the following best explains excretion?

Excretion is the production of sweat from the sweat glands in the skin.

Excretion is the removal of the waste products of metabolism from the body.

Excretion is the removal of excess water and food from the body.

Excretion is the process by which waste products are converted into useful compounds for the body.

Kidney failure can be treated with a long-term solution involving a medical procedure. What medical procedure can be used to treat a small amount of kidney failure patients?

Kidney transplant

Hormone replacement surgery

Pancreas transplant

Stents

The table provided shows the differences between the concentrations of certain substances in blood and in dialysis fluid. Why is it important the concentration of glucose is the same in the blood and in the dialysis fluid?

So glucose does not diffuse out of the blood

So glucose can be actively transported out of the blood

So glucose can be actively transported into the blood

So glucose can be broken down in the fluid to provide energy for the dialyzer

The table provided shows the differences between the concentrations of certain substances in blood and in dialysis fluid. Which of the following statements is correct about the movement of substances?

Sodium will move down its concentration gradient and into the blood.

There will be no net movement of glucose and sodium.

There will be no net movement of urea and calcium.

Calcium will move down its concentration gradient from the fluid and into the blood.

The table provided shows the differences between the concentrations of certain substances in blood and in dialysis fluid. What will happen to the urea?

There will be no net movement of urea.

It will move down its concentration gradient from the fluid and into the blood.

It will be actively transported out of the blood and into the fluid.

It will move down its concentration gradient from the blood and into the fluid.

The diagram provided shows a simplified section of a dialyzer. Complete the statement with “high” and “low” to correctly describe the difference in urea concentrations: The concentration of urea is in the blood and in the dialysis fluid.

High, high

Low, high

High, low

Low, low

The diagram provided shows a basic outline of a dialysis machine. By what process will waste substances move out of the blood and into the dialysate (dialysis fluid)?

Transpiration

Diffusion

Active transport

Translocation

The graph provided shows the number of people requiring a kidney transplant compared to the number of transplants carried out. Which of the following statements about the data correctly describes the trend?

The number of transplants carried out is significantly higher than the demand for kidneys.

The demand for kidney transplants is consistently higher than the number of transplants carried out.

The number of kidney transplants carried out was higher in 1990 than in 2010.

The demand for kidney transplants has slowly decreased over time.

Which of the following is not a major function of a nephron?

Carrying the carbon dioxide released from cells during respiration to the lungs to be excreted.

Filtering waste products from the blood and excreting them as urine.

Selectively reabsorbing useful substances, like glucose, back into the body.

Regulating salt and water concentrations in the body.
