Who first discovered capillaries?

Italian physiologist Marcello Malpighi. 1March 628 10 was born in Cray, 20 kilometers north of Bologna. Valco ray (Crevalcore? Nearby? Bologna),1694165438+1died in Rome on October 30th.

Marcello Malpighi was the first person to use a microscope to discover that arteries and veins are connected by tiny blood vessels, which are now called capillaries. Born in Bologna. He studied at the University of Bologna, and received a doctorate in philosophy and a doctorate in medicine. 1655 Lecturer in Logic, University of Bologna. 1656 Professor of Theoretical Medicine, University of Pisa. 1662 was elected as the chief medical professor of Messina University. 1666 and became a professor at the University of Bologna. 1669 was elected as a member of the Royal Society.

Background of scientific discovery:

Marcello Malpighi's work in microscopy began in1the study of frog lungs in the 1950s. In 1660, he pointed out that blood led to important conclusions. Marcello Malpighi's observation of bat wing membrane enabled him to find the thinnest blood vessel, which was eventually named capillary ("long hair"). These blood vessels are invisible to the naked eye, but they are clearly visible under the microscope. They connect the smallest visible artery with the smallest visible vein.

Marcello Malpighi made extensive microscopic studies on animals and plants, and made important contributions to the development of embryology and anatomy. He was the first scientist to study the structure of animals and plants with a microscope. The most important experiment was to observe the lung structure with a microscope at 1660- 16 1, described the frog's lung capillaries in detail, and wrote the book Anatomical Observation of the Lung.
