8.

Make them more permeable to water (water goes into the blood)
Explain the detailed
functioning of the
kidney (Grade A)
Important in
reabsorption of
water (under
hormonal control)
Correct label and state the function of each part of a nephron (kidney
tubule)
Blood enters the kidney in the
renal artery
________________________
The blood is filtered because it is
under _________________
high
pressure.
________________________
large
molecules stay in the blood
Small molecules pass through the
filter.
Useful molecules are
reabsorbed
________________
Purified blood leaves the kidney in
the
Waste materials leave the kidney in
a tube called the
________________________

ureter
renal vein
Patients who have kidney failure
can’t filter their blood properly –
but a dialysis machine can do it
for them.
How often does dialysis need to
be done?
For upto 10hrs every few days
 Why is the membrane semipermeable?
To allow waste substances to pass
through e.g. urea
 Why does dialysis fluid have the
same concentration of salts and
glucose as blood plasma?
So they aren’t removed from the
blood

Explain the principle
of a dialysis
machine (Grade A)

Where in the body is urea produced?
Liver
What is getting rid of undigested food from the body
called?
Egestion
What is the function of the glomerulus?
Ultrafiltration
What process is used to reabsorb sodium?
Active transport
Why is glucose reabsorbed by the body?
Needed for respiration
What does the presence of glucose in the urine
suggest?
Diabetes
