The large intestine and appendix in humans are vestigial organs from our ancestors, but the appendix now plays a crucial role in producing the microbiome, influencing immune system function. Herbivores have longer digestive tracts with a large cecum and four-chambered stomach for enhanced digestion of cellulose, while marine vertebrates actively regulate internal ion and water concentrations to match their external environment.
Insights
- The appendix, once considered vestigial, is now recognized for its role in producing the microbiome, which influences immune system function and overall health, leading to ongoing research and the use of probiotics.
- Ruminants, such as cows, possess four-chambered stomachs and a large cecum to aid in breaking down cellulose, showcasing specialized digestive adaptations for herbivorous diets, including rumination for enhanced digestion and methane production.
