Practice Listening: Multiple Choice, Single Answer ID: #41017 Short Human Heart
Instructions ›
You will see a video about the structure and function of the human heart. Listen to the recording and answer the multiple-choice question by selecting the correct response. Only one response is correct.

Transcript:

The heart is a pump which drives blood circulation through the body. In fact, it is 2 pumps. The right side receives oxygen-poor blood from the body, seen here in blue and pumps it to the lungs. The left side receives the freshly oxygenated blood from the lungs, seen here in red, and pumps it to the rest of the body. The cardiac cycle or the heart's pumping sequence begins with a period of relaxation. When the blood fills the heart, then the heart contracts and pushes blood through the semilunar valves and into the aorta and arteries, which are the body's pipelines. The entire cycle takes less than a second.

What is the primary function of the heart as described in the video?

Option 3: "To drive blood circulation through the body"

Explanation: This option is correct because the text explicitly states that the heart is a pump that drives blood circulation through the body. This aligns directly with the main idea presented in the text.

Option 1: "To filter the blood and remove impurities"

Explanation: This option is incorrect because the text does not mention filtering blood or removing impurities as a function of the heart. The heart's primary role is to pump blood, not to filter it.

Option 2: "To serve as a reservoir for blood storage"

Explanation: This option is incorrect as the text does not describe the heart as a storage reservoir for blood. Instead, it emphasizes the heart's role in pumping blood throughout the body.

Option 4: "To produce red and white blood cells"

Explanation: This option is incorrect because the text does not mention the production of blood cells as a function of the heart. The heart's primary function is related to pumping blood, not blood cell production.
