Pancreas: The pancreas is a yellowish, lobulated glandular organ situated horizontally across the posterior abdominal wall. In the anatomical model, it is located centrally between the kidneys rather than being the circled lateral bean-shaped organ.

Liver: The liver is a massive, multi-lobed accessory digestive organ located primarily in the right upper quadrant of the abdominal cavity. It is not featured as the circled brown bean-shaped retroperitoneal organ shown.

Adrenal gland: Adrenal glands are pyramidal endocrine structures capped directly onto the superior pole of each kidney. In the model, the adrenal gland sits immediately above the circled kidney rather than being circled itself.

Pancreas: The pancreas is a yellowish, lobulated glandular organ situated horizontally across the posterior abdominal wall. In the anatomical model, it is located centrally between the kidneys rather than being the circled lateral bean-shaped organ.

Kidney: The black circle directly outlines the right kidney in this anatomical model. The kidney is a bean-shaped retroperitoneal organ responsible for filtering blood plasma, manufacturing urine, and regulating systemic fluid and electrolyte homeostasis.

Liver: The liver is a massive, multi-lobed accessory digestive organ located primarily in the right upper quadrant of the abdominal cavity. It is not featured as the circled brown bean-shaped retroperitoneal organ shown.

Right lung: The right lung is a trilobed respiratory organ situated in the right pleural cavity on the viewer's left. The leader line points centrally to the anterior cardiac surface rather than the lateral right lung tissue.

Left lung: The left lung occupies the left pleural cavity, positioned laterally to the heart on the viewer's right. The arrow bypasses the dark, retracted lung parenchyma to point directly at the central pericardial sac.

Liver: The liver is a large, multi-lobed metabolic organ located inferiorly in the abdominal cavity, beneath the diaphragm. The structure indicated lies superiorly within the thoracic cavity between both pleural lungs.

Parathyroid gland: The parathyroid glands are small, oval structures located on the posterior surface of the thyroid gland. They are not visible anteriorly as shown in the image.

Thymus gland: The thymus lies in the superior mediastinum behind the sternum, not in the neck. It is more prominent in children and gradually involutes in adults.

Pituitary gland: The pituitary gland is located within the sella turcica of the sphenoid bone at the base of the brain, not in the neck region.

Kidney: The kidney is a bean-shaped retroperitoneal organ responsible for filtering blood plasma, manufacturing urine, and regulating systemic fluid and electrolyte homeostasis.

Liver: The liver is a massive, multi-lobed accessory digestive organ located primarily in the right upper quadrant of the abdominal cavity.

Adrenal gland: Adrenal glands are pyramidal endocrine structures capped directly onto the superior pole of each kidney.

Common iliac artery: The common iliac artery is a large arterial vessel branching directly from the abdominal aorta. In the image, arterial structures are colored brown/red, whereas the highlighted structure is blue and located lower in the pelvic basin.

Femoral artery: The femoral artery is a primary arterial branch supplying oxygenated blood to the lower extremity. It travels alongside the femoral vein distal to the inguinal ligament, represented by red/brown vascular channels rather than blue highlighted veins.

Inferior vena cava: The inferior vena cava is a large abdominal venous trunk formed higher in the retroperitoneum by the confluence of both common iliac veins. The highlighted vessel lies lower in the pelvis near the inguinal brim.

Kidney: Kidneys are large, dark-red, bean-shaped retroperitoneal organs positioned in the upper abdominal cavity. In the provided diagram, the kidneys are located superiorly, capped by adrenal glands and situated above the pelvic reproductive organs.

Pancreas: The pancreas is an elongated retroperitoneal digestive and endocrine gland running horizontally across the upper abdomen. In the illustration, it appears superiorly in yellow, lying horizontally in front of the upper renal structures.

Uterus: The uterus is a central, pear-shaped muscular reproductive organ situated midline within the pelvic cavity. It connects laterally to uterine tubes, whereas the circled structure represents the lateral oval gonad suspended nearby.

Epididymis: The epididymis lies within the scrotum but is a coiled duct posterior to the testis, responsible for sperm maturation and storage. It is not the external sac indicated by the arrow.

Testis: The testis is located inside the scrotum and produces sperm and testosterone. The image highlights the external covering, not the internal glandular structure.

Prostate gland: The prostate is situated deep within the pelvis, inferior to the urinary bladder and surrounding the urethra. It is not visible in the external genital region shown.

Uterus: The uterus is the thick‑walled muscular organ superior to the highlighted structure. It serves as the site for implantation and fetal development, not the canal shown extending inferiorly.

Urethra: The urethra is a shorter tube anterior to the vagina that conveys urine from the bladder to the exterior. It does not connect to the uterus.

Rectum: The rectum lies posterior to the vagina and is part of the digestive tract, terminating at the anal canal. It is not part of the reproductive system.

Minor calyx: The minor calyx forms a cup-like conduit surrounding the apex of a renal pyramid. It receives urine directly draining from the papillary ducts at the renal papilla. It transports filtrate into larger collecting channels rather than forming the main parenchymal body.

Major calyx: The major calyx represents a large urine-conducting channel formed by the convergence of multiple minor calyces. It directs urine toward the renal pelvis for excretion into the ureter. It consists of transitional epithelium rather than functional nephron tubule segments.

Renal papilla: The renal papilla constitutes the terminal apex of a medullary pyramid protruding into a minor calyx. It contains openings of collecting ducts that discharge urine into the calyceal system. It lacks the broader triangular body marked by the target indicator.
