Which field studies the heart, blood vessels, and blood flow in the human body?

• A. Cardiovascular Anatomy
• B. Respiratory Physiology
• C. Skeletal Bones
• D. Life Span Development

Answer: (A)

The main idea is that this field focuses on the structures of the heart and blood vessels. Cardiovascular anatomy examines the heart’s chambers, the arteries and veins, and how these vessels are organized to form the circulatory network that moves blood through the body. Because the question emphasizes the heart, blood vessels, and blood flow, anatomy of the cardiovascular system is the best fit—it looks at the form and connections that make blood flow possible. If the question had asked about how blood moves or is regulated, you’d think of physiology instead. The other options aren’t about the heart and vessels: respiratory physiology studies the lungs and breathing, skeletal anatomy covers bones, and life span development looks at growth and aging.
