DAANCE module 1
Myocardium - Cardiac Muscle
In what order does blood flow through the heart - Right atrium, tricuspid valve, right ventricle,
pulmonary artery, lungs, pulmonary vein, left atrium, Mitral valve, left ventricle , aorta.
Right atrium receives blood from which three sources? - 1. Superior Vena Cava- above the heart
2. Inferior Vena Cava- below the heart
3. Coronary Sinus- blood from the veins of the heart muscle
Diastolic - The pressure in the arteries
Systolic - The pressure generated in the arteries
bradycardia - below 60 bmp
tachycardia - greater then 100 bmp
SA node (Sinoatrial) - located in the right atrium and acts as the hearts pacemaker. Rhythms that start
from impulses in the SA node are called sinus rhythms.
AV node (Atrioventricular) - located between the atria and ventricles. Transmits electrical impulses to
bundle of His. The bundle of His branches into the right and left ventricles which carry the impulse from
the AV node stimulating the contraction of the ventricles.
Brachiocephalic artery - branches into right common carotid artery
Lingual artery - supplies the tongue and floor of mouth
