Birds, but not humans, have a renal portal type of this anatomical object, which makes their kidney usage more varied. One of these objects in humans is located by the bow and arrow sign at the end of a colonoscopy. That object and its associated sphincter muscle form the boundary between sections of the small intestine. In addition to the ileocecal [ILL-ee-oh-SEE-kul] example of these objects, humans have two of these that are located at the bases of major arteries and two that are atrioventricular, the mitral and the tricuspid. Name these objects that allow liquids such as blood to flow in only one direction.
