strongylus vulgaris lifecycle

A

Enters wall of cecum & ventral colon & penetrates to submucosa -> Molts to L4-> Penetrates adjacent small arterioles -> Migrates to anterior mesenteric artery -> Finally enters lumen & carried by blood to arteries in intestinal wall -> Enter surrounding tissue & form nodule where they molt into adult -> Enter lumen of cecum & colon
