In many vertebrates, including humans, blood flows in two circuits; in an arrangement called double circulation. Which of the following is not an advantage of double circulation over the single circulation organization found in fish?
- Oxygenated and deoxygenated blood are present in separate compartments and prevent mixing of blood.
Oxygenated blood can be mixed with deoxygenated blood before passing through the tissues of the body.
The blood flows to the body tissues under higher pressure and faster, allowing for more efficient delivery of oxygen.
Blood flow to different parts of the body can be regulated more precisely to meet localized oxygen needs.
