Veins
- right atrium
- right ventricle
- left atrium
- left ventricle
pumps low O2 blood to the lungs via the right and left pulmonary ARTERIES
- anterior interventricular artery
- circumflex artery
- posterior interventricular artery
- marginal artery
Where does the coronary sinus recieve blood from'?
- great cardiac vein
- middle cardiac vein
- allow blood to flow from the atria to its ventricle
- close when the ventricle contracts preventing backflow
- pulmonic semilunar valve
- aortic semilunar valve
Functions of the fibrous skeleton
- attatchment site for valves and cardiac muscle cells
- electrical insulation between ventricular and atrial muscle cells
- conducting stem cells
- contractile cells
- cells that contact to pump the blood
- make up 99% of cardiac cells
- sinoatrial node
- atrioventricular node
- conducting cells
