Arteries and Veins
What is the aorta?
These are nicknamed the "strings of the heart."
What is chordae tendineae?
Status of blood in the inferior vena cava. (Oxygenated or deoxygenated)
Deoxygenated
This is the force that blood exerts against the walls of your arteries.
What is blood pressure?
These arteries supply blood to the heart.
What are the coronaries?
This chamber receives venous blood from the body.
What is the right atrium?
Status of blood in the pulmonary arteries.
Deoxygenated
During this phase/action, the ventricles contract and the heart empties.
What is systole?
This is where oxygen is exchanged with carbon dioxide in the circulation.
What are capillaries?
This is the pacemaker of the heart. (Spell it out!)
What is the sinoatrial node?
Arteries move blood (towards/away from) the heart. Veins move blood (towards/away from) the heart.
away from; towards
A recording of electrical events during a cardiac cycle.
What is an electrocardiogram?
This vein is often used to obtain grafts.
What is the great saphenous vein?
The "ears of the heart."
What are the auricles (left and right)?
Blood in the pulmonary veins is coming from directly these organs.
What are the lungs?
An EKG shows an elevation in the ST segment. This is the diagnosis.
STEMI (a type of heart attack)
These vessels bring blood back to the heart. (HINT: one is above and one is below the heart)
What are the superior and inferior vena cava?
This valve is found between the left atrium and left ventricle and has two names. The blood that passes through here is oxygenated / deoxygenated. Your answer must include BOTH names of the valve and the status of blood.
What is the mitral or bicuspid valve; oxygenated
This is how the blood returns to the heart.
This is the phase/action where the ventricles relax and blood fills the heart.
What is diastole?
