Heart Structures
The heart has this many chambers.
What is four?
These vessels transport blood back to the heart and contain valves.
What are veins?
Blood enters the heart through these two large veins.
What are the superior and inferior vena cava?
The two sounds of a heartbeat, “lub” and “dup,” are caused by these closing.
What are heart valves?
This condition is commonly known as high blood pressure.
What is hypertension?
The two lower chambers of the heart are called this.
What are the ventricles?
These vessels carry blood away from the heart.
What are arteries?
The left atrium receives oxygenated blood from this vessel.
What is the pulmonary vein?
This node is known as the heart’s pacemaker.
What is the sinoatrial (SA) node?
A heart attack is also called this.
What is a myocardial infarction?
This structure separates the left and right sides of the heart.
What is the septum?
The largest artery in the body.
What is the aorta?
This artery carries deoxygenated blood to the lungs.
What is the pulmonary artery?
The delay of electrical impulses occurs at this node.
What is the atrioventricular (AV) node?
The hardening and narrowing of arteries due to plaque buildup.
What is atherosclerosis?
This thick, muscular layer of the heart is responsible for contraction.
What is the myocardium?
These small blood vessels are where gas and nutrient exchange occurs.
What are capillaries?
The valve between the right atrium and right ventricle.
What is the tricuspid valve?
The contraction phase of the cardiac cycle.
What is systole?
The condition where the heart fails to pump enough blood to the body.
What is congestive heart failure?
This is the outermost layer of the heart.
What is the pericardium?
Name two common pulse points in the body.
What are the:
Radial
Brachial
Carotid
Temporal
Femoral
Popliteal
Dorsalis pedis
Anterior tibial
Blood exits the left ventricle through this valve before entering the aorta.
What is the aortic valve?
This system controls the heart’s rate and rhythm.
What is the autonomic nervous system?
A life-threatening irregular heartbeat.
What is arrhythmia?
