Does Nathan Lents, author of a “bad design” book really teach biology? A doctor looks at his claims about the human sinuses
From Nathan H. Lents at Skeptic: From neurosurgeon Michael Egnor at ENST: Lents writes: One of the important drainage-collection pipes is installed near the top of the largest pair of cavities, the maxillary sinuses, located underneath the upper cheeks… Putting the drainage-collection point high within these sinuses is not a good idea because of this pesky thing called gravity. Egnor replies: Lents misunderstands the physiology of sinus drainage. The visible opening (ostium) in the maxillary sinus is not the only, or even the main, route of drainage. There is a complex system of interconnection, often at the microscopic level, between the paranasal sinuses, and Lents betrays an ignorance of sinus physiology in asserting that the large visible opening out of Read More ›
