What happens to blood flow in the body when the right side of the heart fails?

• A. Blood flows efficiently
• B. There is no effect on blood flow
• C. There is a back-up of blood in the system
• D. Blood flow decreases to the lungs only

Answer: (C)

When the right side of the heart fails, it can lead to a backup of blood in the system, especially in the systemic circulation. The right side of the heart is responsible for pumping deoxygenated blood to the lungs to receive oxygen. If this side fails, the heart cannot effectively move blood forward, which causes blood to accumulate in the veins. This congestion often results in increased pressure in the venous system, particularly affecting organs and tissues. Signs of this condition may include swelling in the legs and abdomen due to fluid retention, which is known as peripheral edema. Thus, the choice indicating a backup of blood is accurate because it highlights the primary consequence of right-sided heart failure, as blood is unable to flow efficiently to the lungs and instead builds up in the systemic circulation. This has a significant impact not only on the body’s ability to oxygenate blood but can also lead to further complications and symptoms.
