What is the appearance of the renal cortex?

Answer 22

Dark red in colour. Contains the glomerular capsule, the glomeruli and the convoluted tubules of the renal nephrons

Answer 23

Slightly pled red. May be possible to see the renal pyramids containing the loops of hence with the collecting ducts between them

Question 24

What is the appearance of the renal pelvis?

Answer 24

May appear whitish due to the high content of fibrous connective tissue. Basin-shaped structure which drains the urine from the collecting ducts into the single ureter.
