The answer is B. False.
The renal pyramids are cone-shaped structures located in the renal medulla of the kidney. They are primarily involved in the process of urine formation and contain structures known as nephrons, which are responsible for filtering blood and forming urine.
On the other hand, glomeruli are clusters of tiny blood vessels (capillaries) located in the renal cortex, not in the renal pyramids. The glomeruli play a crucial role in the filtration of blood as they are part of the nephron structure, but they are distinctly separate from the pyramids themselves.
