Question
The four statements are about the movement of blood during one complete circuit of the body.
- Blood flowing from the lungs flows through the heart twice.
- All the blood flowing from the lungs flows through the kidneys.
- All the blood flowing from the liver flows through the lungs.
- Only blood flowing from the digestive system flows through the liver. Which of the above statements are correct? A) 1 and 2 only B) 1 and 3 only C) 1 and 4 only D) 2 and 3 only E) 2 and 4 only
Solution
The correct answer is C) 1 and 4 only.
Here's why:
-
Blood flowing from the lungs does flow through the heart twice. Once when it's oxygenated in the lungs and sent to the left side of the heart, and again after it has been sent to the rest of the body and returns to the right side of the heart.
-
Not all blood flowing from the lungs goes through the kidneys. The kidneys do filter blood, but not all of it. Blood from the lungs is sent to all parts of the body.
-
Not all blood flowing from the liver flows through the lungs. The liver does send deoxygenated blood to the heart which then sends it to the lungs, but the liver also sends blood to other parts of the body.
-
Only blood flowing from the digestive system flows through the liver. This is true because the liver processes nutrients from the digestive system.
