Respuesta :
The circulatory system of a whale is considered an organ system because it is composed of different organs.
What is circulatory system of a whale?
- A whale's 4-chambered heart completely separates oxygenated blood from deoxygenated blood, making it a mammal. They have two channels for blood circulation: pulmonary and systemic.
- Since fish have hearts with two chambers, this trait helps differentiate whales as mammals as opposed to fish. A person can fit through a blue whale's arteries by crawling.
- When a blue whale dives to depths of more than 1,000 feet, its heartbeat dramatically slows.
- According to one study, a diving blue whale's heart rate dropped to as low as 2 beats per minute in an extreme effort to conserve oxygen.
- Amazingly, the aortic artery shrank to maintain blood flow in between those beats.
