Cardiac Anatomy
This chamber receives oxygenated blood from the lungs.
What is the left atrium?
Blood returning from the body enters the heart through these two large veins.
What are the superior and inferior vena cava?
These blood vessels carry oxygenated blood away from the heart.
What are arteries?
This phase of the cardiac cycle is when the ventricles contract.
What is systole?
This artery is commonly used when taking a manual blood pressure.
What is the brachial artery?
This valve separates the right atrium from the right ventricle.
What is the tricuspid valve?
After passing through the tricuspid valve, blood enters this chamber.
What is the right ventricle?
These vessels have the thinnest walls and are the site of gas exchange.
What are capillaries?
This phase occurs when the ventricles relax and fill with blood.
What is diastole?
This pulse is palpated on the thumb side of the wrist.
What is the radial pulse?
The heart is located within this cavity of the body.
What is the thoracic cavity (mediastinum)?
This vessel carries blood from the right ventricle to the lungs.
What is the pulmonary artery?
This is the largest artery in the body.
What is the aorta?
The left ventricle has a thicker wall because it pumps blood to this circulation.
What is the systemic circulation?
This pulse is found on the top of the foot.
What is the dorsalis pedis pulse?
This layer of the heart is responsible for pumping blood.- the muscle
What is the myocardium?
These vessels return oxygenated blood to the heart.
What are the pulmonary veins?
These vessels contain valves that help return deoxygenated blood to the heart.
What are veins?
Which side of the heart pumps blood to the lungs?
What is the right side of the heart?
This pulse is located behind the knee.
What is the popliteal pulse?
Name all four valves of the heart.
What are the tricuspid, pulmonary semilunar, mitral (bicuspid), and aortic semilunar valves?
Starting in the right atrium, name the next five structures blood travels through.
Right ventricle → Pulmonary semilunar valve → Pulmonary artery → Lungs → Pulmonary veins
Which heart valve closes immediately before blood enters the aorta?
Aortic semilunar valve
What is the first heart sound (S1), or "lub"?
What is mitral and tricuspid valves close.
This pulse is located in the groin and is commonly assessed during emergencies or before certain cardiac procedures.
What is the femoral pulse?
