How Well Do You Know the Anatomy and Function of the Kidneys?

1. Erythropoietin is synthesized by peritubular capillary endothelial cells.
2. Renin is produced by juxtaglomerular cells and converts angiotensinogen to angiotensin I.
3. Kidneys produce urine by filtering blood and eliminating waste products.
4. Urine contains water, electrolytes, urea, uric acid, and creatinine.
5. Kidneys contribute to maintaining the concentration of substances in body fluids and fluid-electrolyte balance.
6. Kidneys are surrounded by a fibrous capsule and have a hilum where blood vessels and ureter enter and exit.
7. The kidney has a cortex and medulla, with most of the blood flow in the cortex.
8. The medulla contains renal pyramids and papillae, which are surrounded by renal sinus.
9. Radiating lines in the medulla are caused by collecting ducts, nephron tubules, and parallel blood vessels.
10. Foramina papillaris are small openings in the papilla where Bellini ducts open into minor calyces, and the apex with these openings is called area cribrosa.
