Introduction
The kidneys are vital organs that play a crucial role in filtering waste products and excess fluids from the blood. They are positioned in the abdominal cavity, with the right kidney slightly lower in position compared to the left kidney. This difference in position is due to a combination of anatomical factors.

Anatomical Factors
1. Asymmetrical Placement: The placement of organs within the body is not always symmetrical. The liver, which is located on the right side of the body, occupies space that affects the positioning of other organs, including the right kidney.
2. Size and Shape: The right kidney is typically slightly smaller and has a different shape compared to the left kidney. Its shape is influenced by the adjacent liver, which is larger and occupies space in the upper right abdominal cavity. The size and shape of the right kidney may contribute to its lower position.
3. Relationship with Other Organs: The right kidney is positioned under the liver and is located more posteriorly compared to the left kidney. This relationship with neighboring organs influences its position within the abdominal cavity.

Effects and Functions
1. Drainage: The slight difference in position between the right and left kidneys affects the drainage of urine. The right kidney is situated slightly lower, allowing urine to drain into the right ureter at a different angle compared to the left kidney. This anatomical difference does not impact the overall function of the kidneys.
2. Renal Artery and Vein: The right kidney receives blood supply from the right renal artery and drains into the right renal vein. The positioning of these blood vessels is influenced by the overall position of the kidney, including its slightly lower placement.

Conclusion
In summary, the right kidney is slightly lower in position compared to the left kidney due to a combination of anatomical factors. These factors include the asymmetrical placement of organs, the size and shape of the kidneys, and their relationship with neighboring organs. Despite this difference in position, both kidneys function in tandem to maintain the body's fluid and electrolyte balance.

Ans- Because it is due to liver because liver is present on the right side kidney
