Identify the incorrect statement regarding anatomy of human kidney:
| 1. | Adrenal gland is located at the inferior pole of each kidney |
| 2. | Columns of Bertini are extensions of cortex into medulla |
| 3. | Right kidney is slightly lower in location than the left kidney |

The glomerular filtration rate is most affected by:
1. blood osmotic pressure
2. capsular osmotic pressure
3. capsular hydrostatic pressure
4. net filtration pressure
JGA is a special sensitive region formed by cellular modifications in the:
| 1. | DCT and the afferent arteriole at the location of their contact |
| 2. | DCT and the efferent arteriole at the location of their contact |
| 3. | PCT and the afferent arteriole at the location of their contact |
| 4. | PCT and the efferent arteriole at the location of their contact |
The functions of human kidneys do not include:
1. Secretion of renin to regulate GFR and blood pressure.
2. Activating vitamin D.
3. Site of maximum gluconeogenesis in the body.
4. Production of erythropoietin that stimulates bone marrow.
