Identify in diagrams and images the structure of the kidney, limited to the cortex and medulla
Answered step-by-step
To illustrate the structure of the kidney, focusing specifically on the cortex and medulla, here are descriptions of relevant diagrams and their features:
- Basic Kidney Structure:
- A diagram typically shows the kidney divided into two main regions: the renal cortex (outer layer) and the renal medulla (inner layer). The cortex is often depicted as a granular area containing nephrons, while the medulla is shown with cone-shaped structures called renal pyramids that project into the renal pelvis.
- Detailed Cross-Section:
- A cross-sectional diagram of a kidney highlights the cortex surrounding the medulla. The renal pyramids within the medulla are clearly visible, separated by extensions of the cortex known as renal columns. This diagram often labels key structures such as glomeruli in the cortex and collecting ducts in the medulla.
- Anatomy Overview:
- An anatomical overview may include both a lateral view and a cross-section of the kidney, showing how the cortex extends into the medulla and forms renal columns. This illustration emphasizes the relationship between these two regions and their respective roles in filtering blood and producing urine.
