The process in which ammonia is converted to urea. It occurs partly in the cytosol and partly in mitochondria, as ATP is used.

The conversion of toxic molecules to less toxic or non-toxic molecules.

Card 8
Front
The functional unit of the kidney. It is a microscopic tubule that recieves fluid from the blood capillaries in the cortex and converts this to urine, which drains into the ureter.
Back
Card 9
Front
A fine network of capillaries that increases the local blood pressure to squeeze fluid out of the blood. It is surrounded by a cup or funnel shaped capsule shich collects the fluid and leads into the nephron.

Card 10
Front
In this process useful substances are reabsorbed from the nephron into the bloodstream while other excretory substances remain in the nephron.

Card 11
Front
The primary function of these cells appears to be the breakdown and recycling of old red blood cells.

Card 12
Front
A cup-shaped capsule in which blood is pushed into from the glomerulus by the process of ultrafiltration.
Back
Card 13
Front
Brings blood into the glomerulus. Wider than the arteriole which carries blood away from the glomerulus. This helps to increase blood pressure.
Back
Card 14
Front
Filtration at a molecular level - as in the glomerulus where large molecules and cells are left in the blood and smaller molecules pass into the Bowman's capsule.
Back
Card 15
Front
Specialised cells that make up the lining of the Bowman's capsule.
