The Father of Microbiology and the Microscope

For a long time the circulatory system presented an grave puzzle. People could observe arteries and veins, and see that these blood vessels branched away(predicate) into smaller and thinner vessels. Some observers speculated that blood from the arteries returned to the heart th trigger-happy and through veins. However, they had had no means to investigate this. They had reached the limits of human sight. The invention of the magnificence lens microscope by Leeuwenhoek, who was the first to observe unicellular organisms, rough 1668 allowed scientists for the first time to view the most basic fortune of life, the cell. Antony van Leeuwenhoek was an unlikely scientist, born in 1632 into a family of tradesmen in Delft, Holland. He had no fortune, no university education, and knew unaccompanied his native language, Dutch. His turn tail of any formal qualifications or wealth would seem to sprain great odds against him for success in the scientific suit of his time. Howeve r Leeuwenhoeks determination and curiosity allowed him to succeed in create mentally important discoveries in the field of biology. Leeuwenhoek is best known for his gather of the microscope. As a hobby Leeuwenhoek ground lenses and used them to get wind tiny objects. Using these lenses, he observed protozoa in pond water and bacteria in the human rim and intestine. He gave the first full descriptions of bacteria, protozoan, and spermatozoa. The lenses allowed him to discover blood corpuscles and capillaries, and as well to describe the structure of muscles and nerves. His observations laid the foundations for bacteriology and protozoology. In 1595, nearly cardinal geezerhood prior to Leeuwenhoeks birth, compound microscopes had been invented in England by Robert Hooke and in the Netherlands by Jan Swammerdam. These compound microscopes were similar to the ones in use nowadays tho only increased the magn/;ification power by only 20x. Leeuwenhoeks delight in...
