| Which blood vessels supply blood to the head and neck? | The right and left carotid arteries. |
| Which part of the aorta is the most common site for aortic aneurysms? | Abdominal aorta |
| Which part of the aorta supplies blood to the chest wall and lungs? | Thoracic aorta |
| What is the first branch of the abdominal aorta? | Celiac artery |
| What does the celiac artery supply blood to? | Stomach, spleen, liver and part of the esophagus, pancreas and duodenum. |

| What is a AAA? | Abdominal aortic aneurysm |
| What machine may need to be used for repair of an aortic aneurysm? | Bypass machine |
| Which artery eventually turns into the femoral artery and is the major blood supply of the lower extremeties? | External iliac |
| Which arteries supply blood to the pelvic organs? | Internal iliac arteries |
| Which artery is assessed when monitoring a pedal pulse? | Dorsalis artery |
| Which artery would a patient receive a bypass in to improve circulation in a leg? | Femoral artery |
| After a femoral bypass, why would assessing pedal pulses be important? | To assure good blood flow throughout the limb. |
| What is an arterial anastomosis? | An end to end or end to side connection |

| Most of the blood to the liver is provided by which vessel? | Portal vein |
| Why is the circulation different to the liver? | The liver needs blood drained from other vital organs to properly perform its functions. |
| Which vessel supplies oxygenated blood to the liver? | The hepatic artery |
| After draining blood from the liver, the hepatic vein empties where? | Inferior vena cava |
| The right and left lymphatic ducts empty into what? | The right and left subclavian veins |
