Heart Review

What is the largest artery of the heart?

• left atrium

• pulmonary artery

• aorta

Which side of the heart has oxygenated blood?

• left

• right

• niether

How many valves does the heart have?

• 1

• 3

• 4

How does a heart valve work?

• It allows blood to flow out of the designated chamber but does not allow it to flow backward.

• It allows blood to flow out of the designated chamber and flow back in.

• It allows blood to remain in the chamber an indefinite amount of time.

These are the threadlike attachments on the valves that are attached to the papillary muscles.

• Interventricular septum
• Papillary muscles
• Chordae tendineae
• Atrioventricular groove/sulcus

This/these are located in the ventricles of the heart.  They attach to the cusps of the atrioventricular valves via the chordae tendineae and contract to prevent inversion or prolapse of these valves on systole.

• Interventricular septum
• Papillary muscles
• Chordae tendineae
• Atrioventricular groove/sulcus

This forms a wall between the two ventricular chambers.

• Interventricular septum
• Papillary muscles
• Chordae tendineae
• Atrioventricular groove/sulcus

This structure is on the outside of the heart and supplies blood to the myocardium.  

• Auricles
• Left and right coronary arteries
• Pericardium
• Interventricular groove or sulcas

These are vessels that return oxygen-poor blood to the heart.  They are thin walled.

• Veins 
• Venules 
• Arteries 
• Arterioles 

These are vessels that carry oxygen-rich blood from the heart.  They are thick walled.

• Veins 
• Venules 
• Arteries
