  1. Circulatory System

  2. The equine heart is a four-chambered muscular organ split into right and left sides by a septum. Each side has an atrium and a ventricle.

  3. Step One: We breath in oxygen from our mouths, through our throat, to our lungs. • Blood is dumped into the right ventricle from the circulation into the cranial vena cava.

  4. Step Two: • From the Vena Cava takes the poor oxygenated blood then flows through the right tricuspid valve to the right ventricle.

  5. Step Four: The right ventricle contracts to pump the blood through the pulmonic valve and pulmonary arteries to the lungs, where the poor blood is made into oxygenated blood within the red blood cells.

  6. Step Five: • The oxygenated blood returns to the heart by the pulmonary veins to the left atrium and ventricle, which are separated by the left atrioventricular valve.

  7. Step Six:
