💓 Heart Anatomy
What is the name of the sac that encloses the heart?
What is the pericardium?
What is the natural pacemaker of the heart?
What is the SA node?
What are the three main components of the cardiovascular system?
What are the heart, blood vessels, and blood?
What major vessels bring deoxygenated blood into the right atrium?
What are the superior and inferior vena cava?
This disorder occurs when the blood has a reduced capacity to carry oxygen due to low red blood cell count or hemoglobin.
📝 Symptoms include fatigue, pale skin, and dizziness.
What is anemia?
Which layer of the heart wall is responsible for contractions?
What is the myocardium?
What does systole mean?
What is contraction?
What are the three layers of the heart wall from outer to inner?
What are the epicardium, myocardium, and endocardium?
Which side of the heart handles pulmonary circulation?
What is the right side?
This condition involves a blocked or narrowed coronary artery and is the most common heart disease in the U.S.
📝 Often called the “silent killer” and can lead to a heart attack.
What is coronary artery disease (CAD)?
What are the two upper chambers of the heart called?
What are the atria?
What is fibrillation, and why is it life-threatening if not corrected?
What is a rapid, uncoordinated shuddering of the heart muscle that makes the heart useless as a pump, potentially causing death from cardiac arrest?
What are the two major circuits of blood flow in the body called?
What are the systemic circulation and pulmonary circulation?
Where does blood go after it leaves the left ventricle?
What is the aorta/body?
This inherited disorder causes red blood cells to become misshapen and sticky, leading to anemia and painful blockages.
What is sickle cell disease?
What are the names of the two AV valves in the heart?
What are the tricuspid and bicuspid/mitral valves?
What device is used to restore normal rhythm to the heart in cases of life-threatening arrhythmias like fibrillation?
What is a defibrillator (or an implanted pacemaker/defibrillator)?
During fetal development, what two structures allow blood to bypass the lungs?
What are the foramen ovale and the ductus arteriosus?
What vessels carry oxygenated blood from the lungs to the heart?
What are the pulmonary veins?
This condition results in the heart not pumping blood effectively, leading to fluid buildup in the legs and fatigue.
What is heart failure?
What anchors the AV valves to the ventricular walls?
What are the chordae tendineae?
Heart rate below 60 bpm.
What is bradycardia?
What are the names of the four valves in the heart, and what type of valve is each classified as?
What are the tricuspid and bicuspid/mitral valves (atrioventricular valves) and the pulmonary and aortic valves (semilunar valves)?
Why are the walls of the left ventricle thicker than the right?
What is because it pumps blood through the entire body?
This rare condition involves a lack of clotting factors, leading to prolonged bleeding and potential internal bleeding.
What is hemophilia?
