How does a horse’s circulatory system work?

The equine circulatory system transports blood throughout the horse, putting to use the heart, arteries, veins and capillaries. On average, the size of a horse’s heart is about 1 percent of its body weight. Similar to a human’s heart, a horse’s heart has four chambers; two atria that rest above two ventricles.

The horse’s heart is a pump that supplies all its muscles and organs with oxygen andnutrients and carries away waste products. The heart is divided into two sides. The left side takes oxygenated blood from the lungs and supplies muscles and vital organs, such as the brain and kidney.

Subsequently, question is, how big is a horse’s heart? The average adult horse has a 3.6-kilogram (7.9 lb) heart, although it can be more than twice this size. The heart grows until the horse is 4 years of age, although it can increase slightly in size as a response to conditioning. Heart size does not necessarily correlate to the size of the horse.
