| (a) | Ultrafiltration | (i) | Henle's loop |
| (b) | Concentration of urine | (ii) | Ureter |
| (c) | Transport of urine | (iii) | Urinary bladder |
| (d) | Storage of urine | (iv) | Malpighian corpuscle |

In the male, urethra serves to:
1. transport urine from kidney to bladder
2. transport sperms to ejaculatory ducts
3. store urine and sperms
4. discharge semen and urine
The maximum amount of electrolytes and water (70-80%) from the glomerular filtrate is reabsorbed in which part of the nephron?
1. Ascending limb of the loop of Henle
2. Distal convoluted tubule
3. Proximal convoluted tubule
4. Descending limb of the loop of Henle
| 1. | Henle’s loop – most reabsorption of the major substances from the glomerular filtrate |
| 2. | Distal convoluted tubule – reabsorption of ions into the surrounding blood capillaries |
| 3. | Afferent arteriole – carries the blood away from the glomerulus towards renal vein |
| 4. | Podocytes - create minute spaces (slit pores) for the filtration of blood into the Bowman’s capsule |
Consider the following four statements (a–d) regarding kidney transplant and select the two correct ones out of these:
| (a) | Even if a kidney transplant is proper the recipient may need to take immunosuppressants for a long time |
| (b) | The cell-mediated immune response is responsible for the graft rejection |
| (c) | The B-lymphocytes are responsible for rejection of the graft |
| (d) | The acceptance or rejection of a kidney transplant depends on specific interferons |
The two correct statements are:
1. (b) and (c)
2. (c) and (d)
3. (a) and (c)
4. (a) and (b)
