國立陽明交通大學 機械工程學系abstract:
Mammals maintain the flow of nutrition by various forms of fluid such as urine and processed food, and feces. How do animals process and excrete the flow, from mice to elephants? In this talk, I will present that urine is accelerated by gravity in the urethra, which serves as a siphon in the urinary system. Larger animals such as elephants urinate as fast as their smaller counterparts, such as cats. Besides the urination time, I will also present an extreme case of animal processing food in the intestine. Wombat’s have cubic feces inside the last segment of the intestine. The intestinal wall has non-uniform elasticity, thus the contraction of intestine molds four corners. These studies shed light on non-invasive diagnosis of digestive diseases in humans and optimal transport strategies in soft tissue.
