Instructions ›
Read the text and answer the question by selecting all the correct responses. You will need to select more than one response.
The heart actually does two jobs. It pumps the used blood to the lungs and it pumps refreshed blood out to the body. The Bloods root from the right ventricle to the lungs is called the pulmonary circulation. The root from the left ventricle to the body and back is called the systemic circulation. The heart pumps oxygen rich blood from the lungs to all parts of the body through a network of tubes called arteries and smaller branches called arterials. The blood then moves into a network of tiny vessels called capillaries, where the exchange of oxygen and carbon dioxide between blood and body cells takes place. Blood returns to the heart via small vessels called venules, which lead in turn into larger tubes called vein. Carbon dioxide moves out of the body cells and into the blood. It travels in the blood until it reaches the lungs. There carbon dioxide passes from the blood to the alveoli and is expelled from the lungs. When the body exhales.

Option 2: "The pulmonary circulation is the path blood takes from the right ventricle to the lungs."

Explanation: This option is correct as it directly reflects the text, which defines pulmonary circulation as the route blood takes from the right ventricle to the lungs. This is a clear and accurate description of one of the heart's functions.

Option 1: "Blood rich in carbon dioxide travels through arteries to reach the lungs."

Explanation: This option is incorrect because the text states that carbon dioxide moves out of body cells and into the blood, which then travels to the lungs via veins, not arteries. Arteries carry oxygen-rich blood away from the heart, while veins return deoxygenated blood to the heart.

Option 3: "Oxygen-rich blood from the lungs is distributed to the body through capillaries."

Explanation: This option is incorrect because the text specifies that oxygen-rich blood is pumped from the lungs to the body through arteries, not capillaries. Capillaries are where the exchange of gases occurs, but they do not distribute blood to the body.

Option 4: "The systemic circulation carries blood from the left ventricle to the body and back to the heart."

Explanation: This option is correct as it accurately describes systemic circulation, which the text states is the path blood takes from the left ventricle to the body and back. This aligns with the overall theme of the heart's dual circulation system.

Option 5: "Veins carry oxygenated blood from the body cells back to the heart."

Explanation: This option is incorrect because the text indicates that veins carry deoxygenated blood from the body back to the heart. Oxygenated blood is carried by arteries, while veins are responsible for returning blood that is low in oxygen.
