Horses have muscles that act like collar bones, but there is no skeletal attachment of the front leg to the rib cage as in humans.

What circulatory system does a horse have?

The Complete Circulatory System in the Horse

It has four chambers, two atria that sit above two ventricles separated by four valves. Blood returning from the body enters the right side of the heart and the deoxygenated red blood cells (RBCs) fill the right atrium.

Do horses have 5 hearts?

Horses, like other mammals, have only one heart. ... When it is picked up, it contracts and the blood is sent back up the hoof to the heart. Roughly a liter of blood is pumped through the body every twenty strides. Hence, each hoof is a 'heart' giving a horse five hearts.

What is the frog of a horse's hoof?

A flap of tissue called the soft palate blocks off the pharynx from the mouth (oral cavity) of the horse, except when swallowing. This helps to prevent the horse from inhaling food, but does not allow use of the mouth to breathe when in respiratory distress, a horse can only breathe through its nostrils.

Do race horses hold their breath?

Do horses have bigger lungs than humans?

For a healthy horse at rest, however, these 5-liter breaths are easily managed by their 55-liter lung capacity (compared to our 6-liter lung capacity). Although, when undergoing strenuous exercise, a horse's lungs need to work far harder and faster to move enough oxygen to the working muscles.
