We spatially mapped the developing arteriovenous zonation in the embryonic LV ChP in whole explants by combining the pan-endothelial marker PECAM1 with markers for arteries (Acta2+, Vwf+) and veins (Acta2−, Vwf+) (Vanlandewijck et al., 2018). Histological analyses revealed arteries ...
The human heart beats more than two billion times in an average life span and each contraction is precisely controlled by an intricate interplay between electrical signals and mechanical forces. At the anatomical level, it is composed of four cavities, four valves, large arteries, and veins, whic...
(E) Hematoxylin and eosin-stained section of participant 23’s affected tissue, obtained after initial resection. Note the large feeder artery (asterisk), hyper-muscularized veins (arrows), and an area where arteries and veins connect in the absence of a normal capillary bed (dotted oval). ...
and in 1 case there was a compromise of the soft tissue in the same forearm. The shape of the flap was always elliptical and oriented obliquely to the donor limb main axis. Such planning of the flap enables the inclusion of more veins and aids primary closure of the donor site. The pos...
A disease of the arteries in which fatty plaques develop on the inner walls, eventually leading to obstruction of blood flow. atrophy Wasting away of a normally developed organ or tissue. Can occur due to nutritional imbalance, e.g. due to absorption problems caused by chronic diarrhoea. atte...
In one study, PulseCam was used to monitor blood perfusion in the palms of 10 surgical patients as they were undergoinggeneral anesthesia. Rice University’s PulseCam can distinguish small changes in blood flow, like the difference between blocked arteries and veins. Credit: A. Sabharwal/Rice Un...

“parametrium” in surgical anatomy conventionally denotes a poorly defined composite structure including more tissues of different ontogenetic origin (paracervix, mesometrium, parts of the mesobladder and the mesureter). The para-tissues contain a tight network of anastomosing arteries and veins as...
