William Harvey contributed to medicine by proving that blood flows through both veins and arteries and that blood circulation begins at the heart.

Solución

William Harvey made several significant contributions to medicine, particularly in the understanding of blood circulation. Let’s evaluate each statement:
  1. He was the first to dissect human bodies.
    • This statement is not true. While Harvey did perform dissections, he was not the first to do so; dissection of human bodies had been practiced by others before him.
  2. He discovered the liver.
    • This statement is not true. The liver was known long before Harvey’s time, and he did not discover it.
  3. He proved that the same blood flows through veins and arteries.
    • This statement is true. Harvey demonstrated that blood is circulated throughout the body in a closed system, flowing through both veins and arteries.
  4. He showed that blood circulation begins at the heart.
    • This statement is true. Harvey’s work established that the heart is the central organ of blood circulation, pumping blood throughout the body.
Based on this evaluation, the correct contributions made by William Harvey are:
  • He proved that the same blood flows through veins and arteries.
  • He showed that blood circulation begins at the heart.

Extra Insights

William Harvey is best known for his groundbreaking work on the circulation of blood. His meticulous experiments and observations, published in the 1628 book “De Motu Cordis” (On the Motion of the Heart), established that blood circulates through the body in a closed system, with the heart acting as a pump. This was revolutionary at a time when many still believed in the ancient theories of blood flow.
Before Harvey, the concept of blood circulation was largely misunderstood. His work laid the foundation for modern cardiovascular physiology, and his discoveries changed the way medicine was practiced. The idea that blood continuously circulates, supplying oxygen and nutrients while removing waste, was a game changer, leading to advancements in both surgery and overall understanding of human anatomy!
