HOMEWORK STARTER1. State 1 excretory organ
Skin, kidney, liver, lung2. State the 3 layers in the kidney
Cortex, medulla, renal pelvis3. State the name of the tube that goes from the kidney to the
bladder Ureter
4. What is the role of the glomerulus and capsule? Filter the blood
5. Where is urea made? Liver
6. What is urea made from? Excess amino acids
7. What is the name of the hormone that controls the water content of the blood?
ADH (Anti Diuretic Hormone)8. What effect does ADH have on the kidney tubules?
Make them more permeable to water (water goes into the blood)
Correct label and state the function of each part of a nephron (kidney tubule)
Important in reabsorption of water (under
hormonal control) Explain the detailed functioning of the kidney (Grade A)
Blood enters the kidney in the

DIALYSISPatients 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 semi-
permeable? 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)
PLENARY1. Where in the body is urea produced?
2. What is getting rid of undigested food from the body called?
3. What is the function of the glomerulus?
4. What process is used to reabsorb sodium?
5. Why is glucose reabsorbed by the body?
6. What does the presence of glucose in the urine suggest?
Liver
Egestion
UltrafiltrationActive
transport
Needed for respiration
Diabetes
WASTE DISPOSAL PART 1
