Internal Organs of an Obese White Male, Anterior View

Description

Positioned in anatomical orientation, the thoracic and abdominopelvic viscera are presented through an anterior body wall in an obese adult male, with the trachea descending in the midline to the primary bronchi and paired lungs occupying the right and left pleural cavities. Inferior to the diaphragmatic dome, the liver fills the right upper quadrant, while the stomach sits more left sided beneath the left hemidiaphragm, and the small intestine coils centrally with the large intestine framing it peripherally. Running along the midline, the major vessels track cranio caudally, consistent with the course of the thoracic and abdominal aorta and the inferior vena cava, with the heart implied between the lungs, posterior to the sternum. Retroperitoneal kidneys are suggested deep and posterior to the intestines. Obesity changes the practical anatomy you teach and operate on: increased subcutaneous thickness obscures surface landmarks, and a relatively elevated diaphragm reduces thoracic excursion while crowding the upper abdominal organs. Midline vessel emphasis makes this view useful for discussions of central venous access, aortic aneurysm screening, and the relationship of the aorta and inferior vena cava to adjacent viscera during open or laparoscopic approaches. Fat distribution also explains why hepatomegaly from metabolic associated steatotic liver disease can alter the right upper quadrant contour and displace the stomach and transverse colon. Landmarks matter. Use this plate in gross anatomy and radiologic anatomy courses to orient students before CT or ultrasound, and in bariatric surgery or internal medicine materials when explaining why symptoms and exam findings shift with body habitus. It also fits patient education on organ location without overpromising organ detail. Anatomical accuracy verified by SciePro's Medical Advisory Board.
