Completing the puzzle of blood circulation: the discovery of capillaries.
نویسندگان
چکیده
Marcello Malpighi is considered to be the founder of microscopic anatomy. For almost 40 years he used the newly invented microscope to study and discover many structures of human body, animals and plants. One of his greatest contributions to science was the establishment by direct observation of an anatomical linkage between arteries and veins, the capillary network, a monumental work that completed Harvey's theory of blood circulation.

A Computational Study of Oxygen Transport in the Body of Living Organism (RESEARCH NOTE)
Oxygen is an essential part of the living organism. It is transported from blood to the body tissue by the systematic circulation and large part of it is stored in the blood flowing in capillaries. In this work we discuss a mathematical model for oxygen transport in tissues. The governing equations are established assuming that the blood is flowing along a co-axial cylindrical capillary inside ...

متن کاملMathematical Analysis of MHD Flow of Blood in Very Narrow Capillaries (RESEARCH NOTE)
A mathematical model for blood flow in narrow capillaries under the effect of transverse magnetic field has been investigated. It is assumed that there is a lubricating layer between red blood cells and tube wall. The transient flow of the fit red blood cell surrounded by plasma annulus in the narrow capillary is considered. The analysis of fluid flow between red cell and tube wall, when the ce...
متن کاملMalpighi and the discovery of capillaries.
Leonardo da Vinci clearly observed and described capillaries. Using the microscope, Marcello Malpighi examined the brain and major organs to demonstrate their finer anatomical features. This led to his discovery in 1661, of capillaries that proved fundamental to our understanding of the vascular system in the brain and cord. He hypothesized that capillaries were the connection between arteries ...
متن کاملHistorical Perspective: Harvey's epoch-making discovery of the Circulation, its historical antecedents, and some initial consequences on medical practice.
In Harvey's Exercitatio Anatomica de Motu Cordis et Sanguinis in Animalibus of 1628, we see the mechanisms of the Circulation worked out more or less in full from the results of experimental demonstration, virtually complete but for the direct visual evidence of a link between the minute final terminations and initial branches of the arterial and venous systems, respectively. This would become ...
