  Horses have always sparked social and economic interest, awakening in the scientific community an interest in embryology and reproductive biology. To date, little is known about horse embryology because this species has several morphological and physiological characteristics that are peculiar to its own reproductive process. This study describes morphological aspects of developing cardiorespiratory apparatus in equine embryos and fetuses during 20-115 days of gestation. At 21 days, the equine embryo had a forming heart with two chambers and a distinct atrium and ventricle. There was a clear cellular protuberance in the lumen of both chambers and in the region of the endocardium. During this phase, the embryo had a nose rostral to the eyes and dorsal to the mouth, but no speciesspecific characteristics. Only at 40 days did it show external characteristics that were specific to the spec.. Read More»
