Intracellular Digestion-each cell digests its own nutrients Paramecium – a single-celled pond organism
Teeth Indicate Diet
Which digestive system is longer, a carnivore or an herbivore? WHY??
Open vs. Closed Circulatory System Closed = blood is always in the heart or a blood vessel, never in sinuses. Open = blood in sinuses
Amphibian has 3- chambered heart Mammal has 4- chambered heart Fish has 2-chambered heart
Human Heart is 4-chambered: 2 atria and 2 ventricles Left side= blood with oxygen Right side= unoxygenated blood
