2. What is the basic structural and functional unit of kidney?
3. What is main function of kidney?
4. Mention the exact location of kidney.
5. Write two differences in the composition of blood flowing through blood vessels A and B.
6. Name the part of kidney which collects urine for the first time from the nephrons.
7. Define 'Osmoregulation'.
8. Name the technique which is normally suggested by the doctors to the patients in case of a permanent damage to both the kidneys.
   1. Name the hormone which is associated with the 'reabsorption' step of urine production.
9. Draw a neat and labelled diagram of a malpighian capsule.

The figure given below represents a kidney tubule in humans and its blood supply. Study the figure and answer the questions that follow. Write specific name and numbers shown in the diagram for each answer.

1. Name the part which consists of a knot - like mass of blood capillaries.
2. What is the specific name for the combination of parts shown as 5 and 3?
3. Name the part which collects the glomerular filtrate.
4. Where is the most water reabsorbed?
5. Name the part which collects urine in the diagram shown.
6. Which part lies in the medulla of the kidney?
7. Which of the above parts is involved in the process of tubular secretion?
8. How is hydrostatic pressure created?
