Difference between medukka and pyramid in a kidney?(:

I'm sorry, I mean MEDULLA.

To explain the difference between the medulla and the pyramid in a kidney, we need to understand the anatomical structure of the kidney.

The kidney is divided into two main regions, the outer cortex and the inner medulla. The medulla is further divided into triangular-shaped structures called renal pyramids.

1. Medulla: The medulla is the inner region of the kidney and consists of tubules (tiny tubes) that play a crucial role in filtering and concentrating urine. The medulla contains smaller blood vessels, known as vasa recta, which supply oxygen and nutrients to the renal tubules.

2. Renal Pyramid: The renal pyramid is a structure within the medulla. These pyramids are cone-shaped and have a base facing the cortex and an apex called the renal papilla, which points inward toward the center of the kidney. Each renal pyramid contains many microscopic collecting tubules to collect urine from the nephrons (functional units of the kidney) and transport it towards the renal pelvis.

So, to summarize:
- Medulla: The inner region of the kidney that contains tubules involved in urine filtration and concentration.
- Renal Pyramid: Triangular structures within the medulla that contain microscopic collecting tubules to transport urine towards the renal pelvis.

By understanding the anatomical structure of the kidney, we can differentiate between the medulla and the pyramid.
