A closed circulatory system is one in which

• Blood spreads freely throughout the body's tissues

• Blood travels through a system of blood vessels that extend throughout the body

• Blood travels through blood vessels into spongy cavities called sinuses

• Blood travels through a system of blood vessels and air sacs

Oxygen constantly diffuses from air or water into an animal's bloodstream. For this to happen, the concentration of oxygen in the blood must be

• Greater than the concentration of oxygen in the air or water

• Greater than the concentration of carbon dioxide in the air or water

• Lower than the concentration of oxygen in the air or water

• Lower than the concentration of carbon dioxide in the air or water

Reptiles and amphibians have _ chambers in the heart.
