Gangrene following a gunshot laceration of the femoral artery Dry gangrene is caused by acute or chronic loss of blood flow to the distal part of a limb, and is most often seen these days in those with poorly-controlled diabetes and in life-long smokers. However, it can also occur if the limb suddenly loses circulation, such as in a thrombosis (blood clot), or a lacerated artery, as is seen here. Without no circulation, tissues begin to die immediately, and spreads outwards until the point where bloodflow is adequate to keep tissue alive (in this case, probably around the point of laceration). Assuming no bacterial infection took hold above the gangrenous area, and the healthy tissue sealed itself off successfully, the end result without surgery would be the drying up and falling off of the necrotic tissue, in a process known as autoamputation. However, the number of confounding factors in possible autoamputation scenarios is vast, and surgical intervention is called for whenever possible. An American Text-Book of Surgery. Edited by J. William White and William W. Keen, 1894.

Posterior view of arteries and veins of the heart and lungs The coronary sinus is clearly visible, as the largest vein on the body of the heart. “Coronary” means “crown”, so if one thinks of the heart as a head, anything labeled “coronary” likely goes around it in a somewhat-encircling fashion. The anterior cardiac veins drain directly into the right atrium, but the majority of the other cardiac veins (excluding some of the smallest), including the great cardiac vein, drain into the coronary sinus. The junction between the right atrium and the coronary sinus is marked by the Thesbian valve.

Blood vessels and surrounding structures of the kidney Non-pathological veins and arterial vessels. The yellow structure coming off the kidney is the ureter. The renal artery delivers blood to the kidneys, where it’s filtered and has the water-soluble impurities removed. The renal vein returns the filtered blood to the heart, and the waste products are transported to the bladder via the ureter. A Textbook of Genito-Urinary Diseases. Translated by Charles W. Bonney. Dr. Leopold Casper, 1912.

The deep muscles and vessels of the abdominal cavity. Look, if you’ve wanted to cut a guy in half just to see what it looks like inside, you don’t have to. This is what it looks like! Well, it is after taking out all the viscera, intestines, and more superficial organs (which, don’t forget, does not mean they’re organs that are vain and vapid, simply that they’re organs closer to the surface).
