Consider the following statements each with one or two blanks.
(i). Towards the centre of the inner concave surface of the kidney is a notch called (1) through which ureters, blood vesels and nerves enter.
(ii). The medulla of kidney is divided into a few conical masses called (2) projecting into the (3).
(iii). Glomerulus is a tuft of capillaries formed by the (4). artery. Blood from the glomerulus is carried away by an (5) artery.
Which one of the following options correctly fills the blanks in any two of the statements?

Options

A. (1)-renal pelvis, (2)-calyces,(3)-medullary pyramids
B. (2)-medullary pyramids, (3)-alyces, (4)-afferent, (5)-efferent
C. (2)-columns of bertin, (3)-chordae tendinae, (4)-efferent, (5)-afferent
D. (1)-filum, (4)-efferent, (5)-afferent

Answer

To solve the question, we need to fill in the blanks in the statements provided about the kidney. Let's go through each statement step by step.

### Step-by-Step Solution:

1. **Statement (i)**:
- The statement mentions a notch towards the center of the inner concave surface of the kidney. This notch is known as the **hilum**.
- Therefore, the first blank (1) is filled with **hilum**.

2. **Statement (ii)**:
- The medulla of the kidney is divided into conical masses. These conical masses are referred to as **renal pyramids** or **medullary pyramids**.
- Hence, the second blank (2) is filled with **renal pyramids**.
- The renal pyramids project into the **calyx** (plural: calyces), which is the space where urine collects before it moves to the ureter.
- Thus, the third blank (3) is filled with **calyx**.

3. **Statement (iii)**:
- The glomerulus is a tuft of capillaries formed by the **afferent** artery. This artery brings blood into the glomerulus.
- Therefore, the fourth blank (4) is filled with **afferent**.
- Blood from the glomerulus is carried away by the **efferent** artery.
- Thus, the fifth blank (5) is filled with **efferent**.

### Summary of Answers:
- (1) hilum
- (2) renal pyramids
- (3) calyx
- (4) afferent
- (5) efferent

### Final Answer:
The correct fillings for the blanks in any two of the statements are:
- (2) renal pyramids and (3) calyx.
