| Where is the great cardiac vein located? |
|
Definition
| Anterior portion of left side of the heart |
|
|
Term
| Where is the small cardiac vein located? |
|
Definition
| Anterior, right side of heart |
|
|
Term
| What is the main difference between the small cardiac vein and great cardiac vein? |
|
Definition
| Great cardiac vein is on the side of the heart with the left ventricle, that works harder and therefor, has a greater need for gas exchange, the side with the small cardiac vein is just the opposite. |
|
|
Term
| where is the right marginal vein located? |
|
Definition
| Right side, branching inferiorly off of the small cardiac vein. |
|
|
Term
| Where is the middle cardial vein located? |
|
Definition
| posterior portion of heart branching inferiorly to the left off of the coronary sinus. |
|
|
Term

Term
| Where does the myocardium receive it's O2? |
|
Definition
| From coronary circulation |
|
|
Term
| What do cardiac valves (either AV or Semilunar) open in response to? |
|
Definition
| Changes in blood pressure |
|
|
Term
| Why does the right ventricle have less muscle mass than the left ventricle? |
|
Definition
| The right ventricle pumps blood into the pulmonary circuit, while the left ventricle pumps blood into the systemic circuit, the blood in the systemic circuit has further to travel and therefor requires more force. |
|
