Key Stage 3

A drawing of a kidney.

Meaning

Kidneys are organs in the excretory system that removes urea and excess water from the blood.

About the Kidneys

The kidneys are linked to the bladder by ureters.

The kidneys filter the blood to remove some toxic substances.

Key Stage 4

A diagram of a kidney showing the nephrons.

Meaning

Kidneys are organs in the excretory system that removes urea and excess water from the blood.

About the Kidneys

The kidneys are responsible for osmoregulation as well as the removal of urea from the blood.

As blood passes through the kidneys water, urea, glucose and salts diffuse from capillaries into the kidney tubules at in a structure called a nephron. Glucose is completely reabsorbed into the blood while water is selectively reabsorbed depending on the water concentration in the blood.

The selective re-absorption of water is affected by anti-diuretic hormone. When the levels of anti-diuretic hormone are high most of the water is reabsorbed into the blood. When the levels of anti-diuretic hormone are low the water is not re-absorbed and is passed down the ureters to the bladder.
