William Harvey discovered circulation. First, as he tightened a bandage around an arm, he noticed that the fingers
turned blue and cold. Then, he used a less tight bandage and noticed that the hand swelled. With further research,
what conclusion could he reach?
The blood moving toward the hand contains oxygen.
The blood moving away from the hand picks up oxygen.
Veins carry oxygenated blood and are deep in the skin.
Arteries carry deoxygenated blood and are deep in the skin.
Answer:
The blood moving toward the hand contains oxygen.
Explanation:
William Harvey was a physician who discovered blood circulation in the human body. From his experiment, he could conclude that blood moving towards the hand carries oxygen. Thus, option A is correct.
What is circulation?Circulation is the essential process of the body where the blood carrying oxygen and carbon dioxide moves throughout the body for providing energy to the cell.
The circulatory system involves the heart, arteries, veins, capillaries, and many other vessels and organs. The blood hemoglobin carries the oxygen towards the body cells, whereas the veins carry the deoxygenated blood towards the heart.
The arteries and veins are two major vessels of the circulatory system that transports the oxygen and carbon dioxide inhaled and exhaled by the respiratory system.
The arteries and veins are spread throughout the body that transports the blood, so when the bandage is tightened around the hand it stops the flow of blood. As the blood was rich in oxygen it looked like blue color when reacted with the iron of the hemoglobin. As the blood flow was affected it resulted in swelling of the hand.
Therefore, option A. the oxygenated blood is carried towards the hand is correct.
