William Harvey (1 April 1578 – 3 June 1657) [1] was an English physician who made influential contributions to anatomy and physiology. [2] He was the first known physician to describe completely, and in detail, pulmonary and systemic circulation as well as the specific process of blood being pumped to the brain and the rest of the body by the heart (though earlier writers, such as Realdo ...
The blood circulation was famously described by William Harvey in 1628. [20] ... The ABO blood group system was discovered in the year 1900 by Karl Landsteiner.
The modern history of hypertension begins with the understanding of the cardiovascular system based on the work of physician William Harvey (1578–1657), who described the circulation of blood in his book De motu cordis. The English clergyman Stephen Hales made the first published measurement of blood pressure in 1733.
In vertebrates, the circulatory system is a system of organs that includes the heart, blood vessels, and blood which is circulated throughout the body. [1] [2] It includes the cardiovascular system, or vascular system, that consists of the heart and blood vessels (from Greek kardia meaning heart, and Latin vascula meaning vessels).
He is known for being the first to describe the pulmonary circulation of the blood. [26] The work of Ibn al-Nafis regarding the right sided (pulmonary) circulation pre-dates the later work (1628) of William Harvey 's De motu cordis .
The newly discovered manuscript of Ibn al-Nafis was translated by Max Meyerhof. It included critiques of Galen's theory, including a discussion on the pores of the heart. Based on animal dissection, Galen hypothesized porosity in the septum in order for blood to travel within the heart as well as additional help on the part of the lungs ...
The blood was then regenerated in either the liver or the heart, completing the cycle. Galen also believed in the existence of a group of blood vessels he called the rete mirabile in the carotid sinus. [47] Both of these theories of the circulation of blood were later (beginning with works of Ibn al-Nafis published c. 1242) shown to be ...
