The Anatomy of the Kidney and the Nephron - detailed illustration of kidney structure and nephron components.

Let’s solve this step by step.

We are given a diagram of the kidney and nephron with labeled parts (A–O). On the right side, there is a list of terms that need to be matched to the correct letters on the diagram.

The terms listed are:

- RENAL PELVIS → A
- CORTEX → B
- MEDULLA → C
- RENAL ARTERY → D
- RENAL VEIN → E
- NEPHRON → F
- URETER → G

Then below, for the nephron diagram:

- BOWMAN’S CAPSULE → H
- GLOMERULUS → I
- DISTAL TUBULE → J
- PROXIMAL TUBULE → K
- LOOP OF HENLE → L
- CAPILLARIES → M
- COLLECTING DUCT → N
- (and O is likely the ureter or collecting duct outlet — but let’s check)

Wait — actually, looking at the diagram labels:

In the top diagram (kidney cross-section):

- A points to the inner funnel-shaped area → that’s the renal pelvis
- B points to the outer layer → cortex
- C points to the striped middle layer → medulla
- D points to the artery entering → renal artery
- E points to the vein leaving → renal vein
- F points to the tiny filtering unit inside → nephron (though technically nephrons are microscopic, F may point to a group or representative nephron)
- G points to the tube going down → ureter

In the bottom diagram (nephron close-up):

- H is the cup around the glomerulus → Bowman’s capsule
- I is the ball of capillaries inside H → glomerulus
- J is the tubule after the loop → distal tubule
- K is the first coiled part after Bowman’s capsule → proximal tubule
- L is the U-shaped part → loop of Henle
- M is the network of blood vessels around the tubules → capillaries (specifically peritubular capillaries)
- N is the large vertical tube collecting from multiple nephrons → collecting duct
- O is the tube coming out of the collecting duct system → likely continues to renal pelvis/ureter, but in context, it might just be labeled as part of the drainage — however, since “ureter” was already assigned to G, O may not have a term listed? Wait — looking back, the list ends at “collecting duct”, so O may not be labeled in the word bank. But in the diagram, O is shown as the exit vessel — possibly the renal vein or artery? No — in the nephron diagram, O is drawn as a large vessel receiving fluid from collecting ducts — that would be the renal pelvis or ureter, but those are already used.

Actually, re-examining: The word bank has 14 terms, and the diagram has labels A through O (15 labels). Let’s count:

Top diagram: A, B, C, D, E, F, G → 7 labels
Bottom diagram: H, I, J, K, L, M, N, O → 8 labels
Total: 15 labels

Word bank terms:

1. Renal Pelvis
2. Cortex
3. Medulla
4. Renal Artery
5. Renal Vein
6. Nephron
7. Ureter
8. Bowman’s Capsule
9. Glomerulus
10. Distal Tubule
11. Proximal Tubule
12. Loop of Henle
13. Capillaries
14. Collecting Duct

That’s 14 terms. So one label (probably O) doesn’t have a matching term in the word bank? Or perhaps O is meant to be the same as G? But in the diagram, O is in the nephron section.

Looking closely at the bottom diagram: O is drawn as a large vertical vessel on the right, connected to the collecting duct (N). In reality, the collecting duct empties into the renal pelvis, which then goes to the ureter. But since “renal pelvis” and “ureter” are already assigned to A and G in the top diagram, perhaps O is not intended to be labeled with a new term — or maybe it’s a trick.

But wait — in many diagrams, the collecting duct (N) drains into a larger duct that leads to the renal pelvis — and sometimes that’s still called part of the collecting system. However, the word bank includes “collecting duct” for N, so O might be redundant or mislabeled.

Alternatively, perhaps O is meant to be the renal vein or artery again? But D and E are already those.

Let me match based on standard anatomy:

Top Diagram:

- A: Renal Pelvis ✔
- B: Cortex ✔
- C: Medulla ✔
- D: Renal Artery ✔
- E: Renal Vein ✔
- F: Nephron (representative) ✔
- G: Ureter ✔

Bottom Diagram:

- H: Bowman’s Capsule ✔
- I: Glomerulus ✔
- J: Distal Tubule ✔
- K: Proximal Tubule ✔
- L: Loop of Henle ✔
- M: Capillaries (peritubular) ✔
- N: Collecting Duct ✔
- O: ? — This is likely the continuation to the renal pelvis, but since “renal pelvis” is already A, and no other term fits, perhaps O is not required to be labeled, or it’s an error.

But looking at the original image description — the user provided text says:

“RENAL PELVIS_A, CORTEX_B, MEDULLA_C, RENAL ARTERY_D, RENAL VEIN_E, NEPHRON_F, URETER_G, BOWMANS CAPSULE_H, GLOMERULUS_I, DISTAL TUBULE_J, PROXIMAL TUBULE_K, LOOP OF HENLE_L, CAPILLARIES_M, COLLECTING DUCT_N,”

It stops at N. So O is not included in the word bank. Therefore, we only assign up to N.

So the correct matching is:

A - Renal Pelvis
B - Cortex
C - Medulla
D - Renal Artery
E - Renal Vein
F - Nephron
G - Ureter
H - Bowman’s Capsule
I - Glomerulus
J - Distal Tubule
K - Proximal Tubule
L - Loop of Henle
M - Capillaries
N - Collecting Duct

O is not matched because it’s not in the word bank.

Final Answer:
A - Renal Pelvis
B - Cortex
C - Medulla
D - Renal Artery
E - Renal Vein
F - Nephron
G - Ureter
H - Bowman’s Capsule
I - Glomerulus
J - Distal Tubule
K - Proximal Tubule
L - Loop of Henle
M - Capillaries
N - Collecting Duct
