Question
Why is a four-chambered heart more efficient than a threechambered heart?
Step 1
In a four-chambered heart, there are two atria and two ventricles. The right atrium receives oxygen-poor blood from the body and sends it to the right ventricle, which then pumps it to the lungs to pick up oxygen. The left atrium receives oxygen-rich blood from Show more…

In the evolution of circulatory systems, how is a 4-chambered heart advantageous compared to a 3-chambered heart?
What is one advantage of a four chambered heart over a three chambered heart? a. Oxygenated blood carried by the right side of the heart is completely separated from the left side carrying deoxygenated blood, which assists in more efficient movement of oxygen around the body and aids in allowing the body to quickly move when needed. b. A four-chambered heart keeps oxygenated and deoxygenated blood separated and has double circulation whereas a three-chambered heart has a single circulation. This assists in more efficient movement of oxygen around the body. c. Oxygenated and deoxygenated blood are kept separate in a four-chambered heart, which assists in more efficient movement of carbon dioxide around the body. d. Oxygenated and deoxygenated blood are kept separate in a four-chambered heart, which assists in more efficient movement of oxygen around the body and aids in allowing the body to move quickly when needed.
