(To save space in their long, narrow bodies.) * How does the structure of the snake’s jaw help it eat prey larger than its head? (The jaw bones are connected by a stretchy ligament that allows them to spread apart.) * What role does the Jacobson’s organ play in a snake’s survival? (It interprets scent particles collected by the tongue, helping locate prey and detect predators.) * How does the function of the snake’s gallbladder support digestion? (It stores bile, which breaks down fats.) * In what ways is the snake’s three-chambered heart different from a mammal’s four-chambered heart? (It is less efficient at separating oxygenated and deoxygenated blood.)
