Anatomy Flashcards
Blood enter the right atrium through which 2 structures
Superior vena cavae and Inferior vena cava
Which vessel drains blood from above the heart
Superior vana cava
Which vessel drains blood from below the heart
Inferior vena cava
Which vessel from the heart pumps blood into the lungs
Pulmonary artery
The pulmonary artery receives blood from which sections of the heart
right atrium and right ventricle
How many pulmonary veins are there
Four
Where are the entrance of the pulmonary veins found in the heart
left atrium
Blood from the left ventricle exits the heart through which vessel
Aorta
Which wall of the heart is very thick?
The wall of the left ventricle
How many valves are in the heart
Four
Name the four valves of the heart
Tricuspid valve, mitral valve, aortic valve and pulmononic valve
Location of the tricuspid valve
Between right atrium and right ventricle
Location of the pulmonic valve
Between right ventricle and pulmonary artery
Location of the mitral valve
Between left atrium and left ventricle
Location of the aortic valve
Left ventricle and aorta
Which of the heart valves only have 2 cusps/leaflets
Mitral valve
Which chamber of the hearts lies anterior and is usually damaged in chest injuries
Right ventricle
The esophagus sits between which structures of the heart
left atrium (anterior) and aorta (posterior)
Which chamber of the heart, if enlarged can cause dysphagia because of compression of the esophagus
left atrium
Which two coronary arteries branch off the aorta
Left main coronary artery and the right coronary artery
The left main coronary artery bifurcates into which two arteries
left circumflex coronary artery and left anterior descending coronary artery
The left anterior descending coronary artery supplies which section of the heart
Anterior wall of the left ventricle
The left circumflex coronary artery supplies which section of the artery
Lateral wall of the left ventricle
The right coronary artery supplies blood to which areas of the heart
Wall of the right ventricle
The posterior descending coronary artery supplies which areas of the heart
inferior wall of the left ventricle
The posterior descending coronary artery is a branch of which artery in 90% of people
Right coronary artery
The posterior descending coronary artery is a branch of which artery in 10% of people
Left circumflex coronary artery
Venous blood from the myocardium drains into which sinus
Coronary sinus
Which two papillary muscles make up the mitral valve
Anterolateral and posteromedial papillary muscles
Which papillary muscle of the mitral valve has a dual blood supply
Anterolateral papillary muscle
Which blood vessel supplies the anterolateral papillary muscle
Left anterior descending coronary artery and left circumflex coronary artery
Which papillary muscle in the mitral valve is LEAST likely to suffer from ischemia
Anterlateral papillary muscle
Which blood vessel supplies the posteromedial papillary muscle
Right coronary artery or left circumflex coronary artery
Which papillary muscle in the mitral valve is MOST likely to suffer from ischemia
Posteromedial papillary muscle
Where is the sinoatrial node found
lateral wall of the right atrium
What generates electrical activity through the heart
Synovial node
Where is the atrioventricular node located
In the interatrial septum
Electrical signals from the AV travel to the Purkinje fibers through which bundles
HIS bundles, right bundles and left bundles
Where is the HIS bundles located
in the Interventricular septum

Right coronary artery
Which intercostal space is the apex of the heart found
Left fifth intercostal space
The right border of the heart is formed by which structure
Right atrium
The left border of the heart is formed by which structure
Left ventricle
The superior border of the heart is formed by which structures
Right and left auricles plus the conus arteriosus of the right ventricle
The inferior border of the heart is formed mostly by which structure
Right
ventricle
The anterior (sternocostal) surface of the heart is formed primarily by
the right
ventricle
The posterior surface of the heart is formed primarily by
the left atrium
