21.SAGGITAL SECTION OF KIDNEY

A sagittal section of the kidney is a view of the kidney from a side angle, dividing it into left and right halves. In this view, the following structures can be seen:

1. Renal capsule - The outermost layer that covers the kidney.
2. Cortex - The outer region of the kidney, which contains glomeruli, convoluted tubules, and other structures involved in urine formation.
3. Medulla - The inner region of the kidney, which contains renal pyramids, collecting ducts, and other structures involved in urine transportation and storage.
4. Renal pelvis - The funnel-shaped area at the center of the kidney where urine collects before entering the ureter.
5. Ureter - The tube that carries urine from the kidney to the bladder.
6. Renal artery and vein - The blood vessels that supply the kidney with oxygen and nutrients and remove waste products.
7. Nephron - The functional unit of the kidney, responsible for filtering and processing blood to form urine.

In a sagittal section, the nephrons would appear as small, round structures scattered throughout the cortex and extending into the medulla in some areas. Overall, a sagittal section of the kidney provides a detailed view of the internal structures of the organ and is important for understanding the anatomy and function of the kidney.
