Mr. G talks in short bursts with frequent breaths. He tells you he used to feel breathless when he was walking, but now he has b
een having more and more trouble breathing even when he is lying down at night. When you listened to his lungs you heard fluid in them. Could this be due to his heart failure, or is it another problem? Choose the best answer. a. If the left side of the heart fails, it will not pump enough blood to the body, and that means less blood will reach the right side of the heart and be sent to the lungs.
b. The left side of the heart receives blood from the lungs and pumps it out to the body, so if it fails, blood will remain in the lungs.
c. The left side of the heart pumps blood to the lungs, so if it fails, circulation in the lungs will decrease.
d. The left side of the heart does not have anything to do with the lungs, but if it fails, the right side is going to fail too, and then circulation through the lungs will decrease.
In the given question, the condition of the person is mentioned which says that he felt breathless while walking and later while lying down.
The most probable reason for the condition in the give question is that this condition is the result of the failure of the left side of the heart as the left side of the heart that is right atrium receives the oxygenated blood from the lungs and then left ventricle pump the blood to the body.
Since the person is not able to breathe therefore the volume of the lungs is occupied by something in the given case is blood due to the failure of the left heart.
Similarly, your muscles and other parts of your body need to have a continuous supply of glucose (or other high-energy molecules) and oxygen to provide the energy for muscle contraction and other body functions. When your body breaks down glucose, carbon dioxide is produced.
