viruses; bacteria; protozoa; fungi
no - it takes some time
warm (not too hot), moist, food available
when the immune system recognises the
transplant as being "foreign"
using 'artificial kidneys'
drugs block the sites normally used by enzymes
selective reabsorption of sugar, salt and water
occurs - only eliminated by the kidneys if
supplies are plentiful
