Kidney cutaway

Single human kidney in simplified cutaway or partially sectioned anatomical view, preserving the classic bean-shaped external outline and smooth reddish-brown outer capsule with a concave medial hilum. The cut surface reveals internal organization, including a lighter or slightly darker outer cortex, a darker or lighter contrasting inner medulla with gentle pyramidal, striated, or branching patterning, and in more detailed versions a pale central renal pelvis with branching calyces extending inward from the hilum. A short pale ureter may emerge from the medial side. The organ remains compact and smooth externally while exposing simplified internal kidney anatomy in a clean educational style.
