In contrast to humans, birds have a three chambered heart.

Question

BlackTom AI · Accepted Answer

The statement presented is: 'In contrast to humans, birds have a three chambered heart.'
First, recall basic vertebrate heart anatomy: birds, like mammals, have a four-chambered heart consisting of two atria and two ventricles, which allows complete separation of oxygenated and deoxygenated blood.
Next, compare this with the idea of a three-chambered heart. A three-chambered heart is typical of many amphibians and some reptiles, where there is usually two atria and one ventricle, or other partial separations that do not achieve full separation of blood streams.
Because birds are known to have a complete four-chambered heart, the claim that they have a three-chambered heart is incorrect.
Additionally, noting the distinction helps explain why birds can efficiently support high metabolic rates for flight, a feature enabled by complete separation of pulmonary and systemic circuits in a four-chambered heart.
In summary, the assertion conflicts with established anatomical knowledge: birds possess a four-chambered heart, not a three-chambered one, making the statement false.
