Monogastric

The video tutorial explores various digestive systems, starting with unicellular organisms that use phagocytosis. It then discusses the evolution from the gastrovascular cavity in cnidarians to the alimentary canal in nematodes. The tutorial covers the four types of vertebrate digestive systems: avian, monogastric, ruminant, and pseudoruminant. It focuses on the monogastric system found in mammals like humans and pigs, detailing the process of digestion and nutrient absorption.
