Read the following statements and choose the follwoing option: 1. Cortical nephron has short loop of Henle 2. Peritubular capillaries are formed by afferent arteriole 3. PCT open into collecting ducts 4. A hairpin shaped Henle’s loop is the part of the tubule which has a descending and an ascending limb 5. The DCTs of many nephrons open into a straight tube called collecting duct
Options
- AOnly 1 and 4 are correct
- BAll are incorrect
- CBoth 2 and 3 are correct
- DAll are correct
Correct answer
A. Only 1 and 4 are correct
Step-by-step solution
In majority of nephrons, the loop of Henle is too short and extends only very little into the medulla. A hairpin shaped Henle’s loop is the next part of the tubule which has a descending and an ascending limb. The ascending limb continues as another highly coiled tubular region called distal convoluted tubule (DCT). The DCTs of many nephrons open into a straight tube called collecting duct.
