Diagram of the 26S proteasome showing polyubiquitin-tagged protein being unfolded and translocated into the 20S core by ATPase activity, leading to peptide degradation.

Anatomical illustration of the juxtaglomerular apparatus showing the glomerulus, Bowman's capsule, afferent arterioles, juxtaglomerular cells, and macula densa cells.

The image displays the nephron, the functional unit of the kidney, alongside a zoomed-in view of a kidney from the medulla. The nephron is featured, showing its key structures such as the glomerulus, proximal tubule, loop of Henle, and distal tubule.

Stomach and pancreas with type 2 diabetes indicators, including insulin, glucose, and pancreatic islet cells

Detailed anterior view of the human heart showing the four chambers, major vessels, interventricular septum, and valves for understanding cardiac function.

Image showing intestinal villi, highlighting swollen lymphatics, blunted villi with lymphangiectasia, ruptured lymphatics, and normal structures like crypts, blood capillaries, and mucosal layers.

Diagram illustrating the cancer-immunity cycle, showing how tumor cells release antigens that are picked up by antigen-presenting cells, which activate T cells in lymph nodes. These T cells then target and destroy tumor cells, releasing more antigens and perpetuating the cycle, crucial for developing cancer immunotherapies.

Illustration showcases the breast anatomy and ribcage underneath.

Anatomical illustration of the pelvis showing indirect inguinal, direct inguinal, and femoral hernias.

Visualizing liver nerves is hard due to their small size, complex anatomy, and surrounding structures.

Illustration of serratus anterior muscle showing origin, insertion, function, and key nerves and arteries.

Illustration of lymph nodes in the lungs and mediastinum, color-coded to highlight bronchial, hilar, mediastinal, and subcarinal nodes based on the Mountain-Dresler lymph node map.
