Scientists of the Unit of Physics, associate professor Ph.D. Selim Pašić (as corresponding author) and Ph.D. Nato Popara (as the first author) have published a scientific paper entitled “Considerations on static pressure gradients in closed circulatory systems” in the well-known American journal of physiology Physiological reports (IF 2.99) (https://physoc.onlinelibrary.wiley.com/doi /10.14814/phy2.15983 ). In the paper, using the laws of physics, they proved mathematically that in the circulatory system of humans and animals there is a gradient of static blood pressure and that it is equal to the gradient of hydrostatic pressure. With this, they solved a multi-decade dilemma in the physiology of blood circulation, since some authors claimed that the gradient of static pressure either does not exist or that it is different from the gradient of hydrostatic pressure, especially when they considered the siphon as the best model of blood circulation.
