👉 Calyces are a type of kidney that is specialized for filtering waste products from the blood. They consist of two main structures: the collecting duct, which carries waste products to the ureters (the tubes that carry urine out of the body), and the renal pelvis, which contains the ureteric antrum, the urethra, and the ureter. The calyces have a small diameter compared to other parts of the kidney, allowing for efficient filtration.
