Final answer:
A snake's stomach works relatively harder than a human's due to its specialization in breaking down consumed meat. Snakes digest their food by secreting powerful enzymes in their highly acidic stomach, where most of the digestion takes place, unlike human digestion which is assisted by multiple organs.
Step-by-step explanation:
Digestive Structure Working Harder in Snakes
Since snakes eat only meat, their digestive system is highly specialized for breaking down animal tissue. In comparison to the human digestive system, a snake’s stomach works relatively harder. Snakes possess a highly acidic stomach that secretes powerful digestive enzymes capable of dissolving and absorbing everything from their prey, except hair and claws. The digestion process begins when the snake swallows other animals whole. The potent gastric juices and the acidic environment of the snake's stomach efficiently break down protein-based tissues. Unlike humans who have a monogastric digestive system with different components supporting digestion, such as teeth for mastication and digestive enzymes produced by the pancreas and liver, snakes rely heavily on their stomach for the bulk of the digestion process. So, when comparing the two, the digestive structure that works harder in snakes relative to humans is their stomach.
