William Harvey - Heart

 We can only survive as long as our heart beats. Science tells us that when the heart stops beating, the blood flow stops and our life is cut short. But it is a wonder that the world did not know this reality 400 years ago. Biologists at the time had misconceptions about blood flow and heart function.For example, there were various opinions that contradicted the fact that the food we eat goes into the heart and turns into blood, that the heart is used to heat the blood, that there is only air in the blood vessels, and that the blood sometimes flows inwards and outwards from the heart. The heart pumps blood throughout the body.We are going to learn about an amazing medical genius who changed the face of medicine by first discovering to the world the fact that blood travels repeatedly within the body.The medical genius William Harvey was born on April 1, 1578, in Folkestone, England. His father was a well-to-do businessman who attended the prestigious King's School and the University of Cambridge.Harvey didn’t shine as much at university. So, then none of his professors would have thought that he was going to discover the most important fact of the medical world. But Harvey is someone who can give hard work even if it doesn’t shine. 

In 1597, Harvey studied medicine at the University of Padua, Italy, the world's foremost medical university at the time.He returned to England after graduating with a medical degree from the University. He was again educated at the University of Cambridge. He then began his own medical career. 1609 St. Harvey was admitted to Bartholomew's Hospital.Harvey began collecting various information from the many patients who treated him at the hospital. Harvey believed that everything that had been believed up until then about the work of blood in the body and about blood flow was wrong. But he did not immediately understand the truth of such things. He did many researches for many years to know the truth.He patiently researched the carcasses of humans, animals, birds, frogs, snakes, rats, and rabbits. He read very carefully all that had been written up until then about blood and human anatomy without leaving a single one. He learned about the fact that valves are found in blood vessels through a doctor named 'Hieronymus Fabricius'.But no one understood the workings of the avalanches. Harvey realized that avalanches prove that blood flows in only one direction. Next he predicted that two ounces of blood would come out of it every time the heart beat. The heart beats approximately 72 times per minute. That is, 144 ounces per 60 seconds (a) of 540 pounds of blood per 60 minutes must leave the heart.But, 540 pounds is much higher than the average human weight. Therefore, he assumed that the blood flowed from the heart and traveled in the same direction throughout the body and then re-entered the heart and flowed again. He worked very hard for the next 9 years to confirm his faith and underwent several tests about blood flow.Harvey lectured on his invention 12 years before it was published as a novel. But the only gifts he received were indifference and ridicule.

In 1628, in his 50s, he published a book, An Anatomical Disquisition on the Motion of the Heart & Blood in Animals. The whole medical world came to a standstill. It has been criticized by many as a farce that has been believed for more than fifteen centuries. The number of people coming to him for treatment was rapidly declining. But all those who thought that Harvey's claim should be falsified embraced the failure of the soil, as if Adam had not disappeared even though 1000 hands were hidden.The medical world soon realized that what Harvey had said was an undeniable fact. Harvey's influence and fame then began to skyrocket. His medical career began to shine brightly. Do you know which of these is really surprising?...A microscope-like microscope is essential to perform and confirm such a microscopic discovery. But no such tool was invented in Harvey's time. What the world really needs to appreciate is that Harvey discovered some of the most remarkable facts in the history of anatomy without any modern medical research tools.The Royal European Hospital, which initially opposed Harvey's claim, later bowed to the genius of the medical genius. 1654 wanted to give him the highest honor in the medical field. Harvey was asked to become president of the association. But Harvey, who never expected fame and recognition, turned down the honor.In return, Harvey built a new building for the academy with a library containing a lot of good books and a museum with research rooms.

Harvey, who made the breakthrough in anatomy, was diagnosed with rheumatoid arthritis. She died on June 3, 1657, at the age of 79. Although Harvey's family life was happy, the Harvey couple had no children. So he wrote his entire estate on top of the Royal Hospital.He appealed to the members of the Royal Clinic to discover and publish the secret of nature through relentless research. Allocated the necessary funds to conduct annual lectures at the Institute. Harvey has been lecturing annually for over 350 years to this day. The annual tribute that the medical community can make to this man.William Harvey's lofty lifelong goal was to overcome illness and pain by developing our knowledge of the secrets and facts of the human body.Man's life became meaningful as he traveled towards the intended goal with clear thinking, hard work, hard work and perseverance.He achieved his greatest goal in the medical world. There is still a lot of facts for humanity to discover and goals to go. The heartfelt truth that William Harvey wanted to tell everyone about 350 years ago would be that everyone who travels in search of it with confidence can achieve his goal.
