"Can you match these old-timey illustrations with the correct illnesses?"
For centuries, researchers have studied the brain to find exactly where mechanisms for producing and interpreting language reside. Theories abound on how humans acquire new languages and how our developing brains learn to process languages.
Tree-barking of the aorta
Before rupture occurs, infamous ‘tree bark’ grooves appear on the inner layer of the aorta.
They are basically stretch marks of the aorta and can be seen in cases of Marfan-style dilatation of the aortic root. The reason you can’t see them in cases of atherosclerosis is because the markings are masked by plaques.
This makes a lot of sense.

Bottom picture: His patient who survived and actually went on to outlive Dr. Religa.
Dr. Religa was also the first surgeon to graft an artificial valve using materials from human corpses. He lead a team that completed the first successful heart transplantation in Poland. Him and his team obtained the Brusseis Eureka award for developing an implantable pump for a pneumatic heart assistance system.

Anatomy and Position of the Kidney in the body
The kidney is a fascinating and under-appreciated organ. Even its name is interesting: while the Greek nephros and the Latin renes are both used as medical terms for the kidney and its anatomy, the origin of the common name in English - “kidney” - is actually unknown. It may be from the Old English terms cwið (womb) + ey (egg), from its shape, but there is no clear consensus on its origins.
The kidney serves many functions, but its most obvious is creating urine. The process of doing that is surprisingly complex, and involves regulation of blood pressure, re-absorbing vital nutrients, excreting urea from protein catabolism, and secreting hormones such as erythropoietin (which stimulates red blood cell creation).
These are four major sections of the kidney:
- Capsule - A tough, fibrous layer of tissue, surrounded by a thick layer of fat, which protects the kidney.
- Cortex - Just inside the capsule, the outermost layer of the kidney itself, which contains renal corpuscules and tubules. Ultrafiltration and erythropoietin production happens here.
- Medulla - The inner tissue of the kidney, split up into renal pyramids. This is where the arteries split up, serum comes out of the blood, and ions and glucose are processed.
- Renal Pelvis - This is the convergence point of the major calcyes, and funnels urine into the ureter, which goes to the bladder. The transitional epithelium in this section of the kidney is the cause of many types of kidney cancers.

Eyes: The Windows to Your Health
Your eyes are tiny spheres of wonder. A doctor can find warning signs of high blood pressure, diabetes, and a whole range of other systemic health issues, just by examining your eyes. Ophthalmologist Neal Adams explains why the eye’s tissues and blood vessels make such a good barometer for wellness.
