| Describe the vessels connected to the left hand side of the heart | - Aorta connected to the LV pumps O blood to the body - Pulmonary vein connected to the LA brings O blood from the lungs |
| Describe the vessels connected to the right hand side of the heart | - Vena cava connected to the RA brings dO blood from body. - Pulmonary artery connected to RV takes dO blood to lungs |
| What is the name of the blood vessel that supplies the heart muscle with oxygenated blood? | The coronary arteries supply the heart with oxygenated blood, they branch off of the aorta into two main arteries covering all of the heart. |
