William Harvey's discovery

The transcript describes a series of experiments conducted to understand the heart's function and blood flow. Initially, the dissection of cold-blooded animals allowed for the observation of heart muscle movements. Further experiments involved dissecting human hearts to demonstrate that blood flows in one direction. The researcher faced skepticism from those who believed in Galen's theory, so they meticulously measured blood volume and gathered evidence to support their findings before publication.

What was the primary reason for dissecting live cold-blooded animals?

• To study their digestive system

• To observe the slow movements of heart muscles

• To understand their respiratory system

• To examine their nervous system

What method was used to demonstrate that blood flows in one direction?

• Measuring blood pressure

• Injecting dye into the bloodstream

• Pumping liquids past vein valves

• Using a microscope

What was the purpose of pushing thin rods into the veins?

• To block the veins

• To demonstrate unidirectional blood flow

• To prove blood flows in both directions

• To measure blood pressure

Why was it important to measure the amount of blood moved by each heartbeat?

• To assess the health of the heart

• To find out the oxygen level in blood

• To determine the heart rate

• To calculate the total blood volume in the body

How did the researcher prepare for those who doubted his findings?

• By ignoring their opinions

• By gathering detailed proof and calculations

• By conducting more dissections

• By publishing a book
