Gills require a direct route of oxygenated blood to reach them for gas exchange with the environment. A two-chambered pump (with one atrium and one ventricle) allows for separation of oxygenated and deoxygenated blood, ensuring that oxygen-rich blood is consistently delivered to the gills for efficient gas exchange. This adaptation was necessary for fish to survive and thrive in their aquatic environment.
