Which of the following is NOT a part of the human kidney?
A
Renal medulla
B
Alveolus
C
Nephron
D
Renal cortex
Verified step by step guidance1
Step 1: Begin by understanding the anatomy of the human kidney. The kidney is a vital organ responsible for filtering blood and producing urine. It consists of several key structures, including the renal cortex, renal medulla, and nephrons.
Step 2: Define each term provided in the options:
- Renal cortex: The outer layer of the kidney where filtration begins.
- Renal medulla: The inner region of the kidney containing structures like the renal pyramids.
- Nephron: The functional unit of the kidney responsible for filtration, reabsorption, and secretion.
- Alveolus: A structure found in the lungs, not the kidney, responsible for gas exchange during respiration.
Step 3: Compare the options to the anatomy of the kidney. Identify which term does not belong based on its function and location in the body.
Step 4: Recognize that the alveolus is part of the respiratory system, not the urinary system, and therefore is not a part of the kidney.
Step 5: Conclude that the correct answer is 'Alveolus,' as it is unrelated to kidney anatomy.
