Answer the following question given this paragraph: To keep their flight muscles well supplied with oxygen, birds evolved specialized respiratory and circulatory systems. Birds have special air sacs for storing extra air and pumping it into the lungs. They also have a relatively large heart and a rapid heart rate. These adaptations keep plenty of oxygenated blood circulating to the flight muscles. Q: Birds have a relatively large heart and a rapid what? Choices: - lifespan - blink rate - digestive process - heart rate A:
(A).
heart rate
