INDEX of notes on homeostasis - kidneys and osmoregulation
water content control - ion and glucose concentrations - kidney
function - associated liver function - kidney failure - dialysis
Doc
Brown's biology exam revision study notes
See
also homeostasis - blood sugar control - diabetes
and homeostasis - thermoregulation and temperature control
This page will help you answer questions
such as ... How does the body control its water content? Why is it important for the body to
control its water content? How do the kidneys work? Why are the
kidneys important? What can you do about kidney failure?
Sub-index for this section on kidney
function and osmoregulation
(1)
What
is osmoregulation and why is it needed?
(2)
The functions of the kidneys
(plus mention of associated liver function)
(3)
Some
details on how the kidney works in conjunction with the urinary and blood systems
(4)
More on controlling
water content - water input and output - water balance
(5)
Hormone controlled water concentration of the blood and urine -
ADH negative feedback
mechanism for water balance
(6)
More on
controlling ion concentrations and removing waste products and problems
resulting from malfunctioning kidneys and kidney failure (plus mention of
associated liver function)
(7)
Dialysis - an artificial means of
purifying the blood
(8)
Kidney transplants
and problems - transplant or dialysis? 'Pros and Cons'
Practical work to
help develop your skills and understanding may have included the following:
dissecting and making observations of a kidney
designing a model kidney dialysis machine using Visking tubing as the filter
testing urine from diabetic and non-diabetic people using Clinistix.
Be able to evaluate the advantages and disadvantages of treating
kidney failure by dialysis or kidney transplant,
