What is the right atrium?
Blood in the right ventricle is headed towards the...
This artery is inferior to the left auricle and branches into the anterior interventricular artery and the circumflex artery.
What is the Left Coronary Artery?
The structure that anchors the chordae tendinae of each atrioventricular valve.
What is a papillary muscle?
This node is the pacemaker of the heart.
What is the Sinoatrial (SA) node?
What is the myocardium?
Blood in the pulmonary veins is headed to...
Left atrium
This artery supplies the right atrium and divides into the posterior interventricular and marginal branches.
What is the right coronary artery?
The irregular muscle ridges found in the ventricles.
What are the trabeculae carnae?
This tissue provides a smooth lining for the chambers of the heart.
What is the endocardium?
The valve connecting the right ventricle and pulmonary trunk.
Bonus +100 if you can name what kind of valve.
What is the pulmonary valve?
Semilunar valve
Blood in the left atrium flows through what valve?
Bicuspid (mitral)
This artery lies in the coronary sulcus and supplies blood to the right ventricle.
What is the marginal artery?
The valve connecting the left atrium and ventricle.
Bonus +100 if you can name the kind of valve.
What is the bicuspid/mitral valve?
Left Atrioventricular Valve, Left cuspid valve
When the atrioventricular valves are open, the semilunar valves are ________.
Closed
Adheres to the surface of the heart, is the visceral layer of the serous pericardium.
What is the epicardium?
Blood in the left ventricle is will flow through what valve?
Bonus +100 if you can name what kind of valve.
Aortic valve
Semilunar Valve
This vein lies in the anterior interventricular sulcus and drains the anterior portion of the heart.
What is the great cardiac vein?
The special ridge found in the right ventricle that is part of the conducting system, coordinating contractions of cardiac muscle cells.
What is the moderator band?
Blood coming from the inferior portion of the body (ex: feet) travels up and flows into the RA by what vessel.
What is the inferior vena cava?
These muscles are found in the right and left auricles and the anterior wall of the right atrium.
What are pectinate muscles?
Blood in the ascending aorta can travel through what 3 smaller vessels branching off of the aorta?
Brachiocephalic, left common carotid, left subclavian arteries.
The vein lies in the coronary sulcus and drains the right atrium and right ventricle.
What is the small cardiac vein?
This tissue is the "bag" that rests on and attaches to the diaphragm, surrounding, anchoring, and protecting the heart.
What is the fibrous layer of the pericardium?
This artery lies in the coronary sulcus on the posterior aspect of the heart, supplying the left ventricle and atria with oxygenated blood.
What is the circumflex artery?
