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.

Liver Vasculature and Ducts

On top, the small vessels shown are are the branches of the vena cava in the liver. The large vein behind those vessels is the vena cava ascendens. 

On bottom, the pouch labeled “4” is what Cheselden called the “cystis hepaticus” - the gall bladder. You can see the ductus cysticus coming off of the gall bladder, and the ductus hepaticus underneath it (this duct is actually posterior to the gall bladder in most cases, not underneath). The small vessels shown are the ductus pancreaticus, and the area labeled “8” is the entrance of the ductus communis into the duodenum.

Fig 1. Dactylitis syphilitica - Look, just don’t get syphilis, ok? It hates your entire body, not just your genitals.

Fig 2. Digitale angiome - A benign tumor of the blood vessels or lymphatic system (most likely of the blood vessels), found on the finger.

Fig 3. Digitale angiome - Same as above, with multiple growths forming nearby one another.

Fig 4. Congenitale diffuse Angiektasie der oberen Extremitaten - Diffuse congenital dilation of the blood vessels of the upper extremities. This is often caused by poor valves within the veins that keep the blood flowing back toward the heart, leading to pooling of blood and expansion of the vessels. It’s the same as secondary varicose veins, but is present from birth, and is often more extensive.

The nerves [yellow] and blood vessels [blue and red] within the spongy bone of the jaw.

This is what I have for my icon right now. The buccal plates are partially removed to show the path of the vessels and nerves into the teeth.

Forms of obstruction at the orifice of the pulmonary artery, with irregular course of the aorta

Fig 1. Form of the valvular apparatus in obstruction of heart of child 10 or 12 years of age.

Fig 2. Drawing of obstruction at outlet of right ventricle. Note that there are two valves instead of three, though one of the two appears to have been formerly divided. Orifice is of considerable size, though obstruction at exit of ventricle is still extreme. Removed from girl 19 years of age.

Fig 3. Case in which pulmonary artery was of small size, probably from premature obliteration of arterial duct. Aorta arose from right ventricle, crossed over right bronchus, passed behind trachea, and gave off four vessels - the right and left carotid and the right and left subclavian arteries. Removed from a boy 11 1/2 months old.
