What are renal pyramids?
Answers
Renal pyramids (or malpighian pyramids or Malpighi's pyramids named after Marcello Malpighi, a seventeenth-century anatomist) are cone-shaped tissues of the kidney. The pyramids consist mainly of tubules that transport urine from the cortical, or outer, part of the kidney, where urine is produced, to the calyces, or cup-shaped cavities in which urine collects before it passes through the ureter to the bladder. The point of each pyramid, called the papilla, projects into a calyx.

What are renal pyramids?
❖ Renal pyramids appear as though they are striped because they are situated in segments of parallel nephrons. The nephron is the basic functional and structural unit of the kidney that filters the blood that regulates water concentration and soluble substances such as sodium salts.
