HORMONES/HOMEOSTASIS
The main job of the kidneys is to regulate he amount of water in the body + balance the conc. of mineral ions in the blood
The amount of water in the blood must be kept constant to avoid cell damage as a result of osmosis
ADH controls the reabsorbtion of water in the kidney tubules
Erythropoietin is a hormone which controls how fast new RBC are made
People with kidney failure do not make enough of this
AS a result they become anaemic

DIABETES

This is because your pancreas doesn't produce any insulin or not enough insulin to help glucose enter your body's cells
There are 180 million people worldwide that suffer from diabetes
2.5 million in the UK
Diabetes can cause problems with the heart and circulation, kidney damage and blindness
Worldwide 4 million people die each year from disorders associated with diabetes
The kidneys produce urine and get rid of waste products e.g urea
They retain glucose and protein ( useful) so none is lost from the body
We have 2 kidneys in the back of our body around the size of a fist
Part of the uriary system and are connected to the bladder by the ureters
Kidney failure can occur due to trauma or an accident envolving the kidney
Diabetes is one of the main causes of kidney failure
