Final answer:
To view both kidneys' internal anatomy simultaneously, a coronal section would be used. This plane cuts the body into front and back halves, revealing the retroperitoneal position and layered structure of the kidneys, including the renal cortex and medulla.
Step-by-step explanation:
To view the internal anatomy of both kidneys at the same time, an anatomical section must intersect both kidneys in such a way that it displays their internal structures. The type of section that would accomplish this is a coronal section, also known as a frontal section. This plane would cut the body (and therefore the kidneys) in a way that divides it into front and back halves, providing a simultaneous view of the right and left kidney.
The kidneys are retroperitoneal organs located on each side of the spine, just below the diaphragm, and are surrounded by three layers of protective tissue. Externally, these layers are the renal fascia, the perinephric fat capsule, and the renal capsule. Internally, each kidney consists of an outer renal cortex and an inner renal medulla, with cone-shaped renal lobules, nephrons, and renal pyramids, designed to filter blood and produce urine.
