Flow
What comes after the body
Vena cava
What is the myocardium
Muscle layer of the heart
SA node
Pacemaker
What is the function of valves
Valves work like doors allow flow and stop backflow
Mitral and tricuspid are the same thing?
True
What two come after the pulmonic valve
Pulmonary artery, and lungs
Inner layer of the heart
Endocardium
AV node
Causes contractions (located under right atria)
What are valves made of
Cordanea tendinea
What is the dub
Pulmonary and aortic valves closing
What 3 steps come after the pulmonary vein
Left atrium, mitral valve, left ventricle
What is the tunica adventiva
Protection / nerves
bundle of his
Next to av node and slows down signal
Where are valves located
Between each chamber of the heart
What contracts in unison
Top layer and bottom layer
What comes before pulmonic valve
Right ventricle
Tunica media function
Middle layer (muscle)
Bundle of branches
Splits signals
What is the connection between muscles and valves
Muscles allow for valves to open and close
What is sickle cell
Blood can’t flow, causes pain, boomerang shape
Name the whole flow starting at the body
Vena cava, right atrium, tricuspid valve, right ventricle, pulmonic valve, pulmonary artery, lungs, pulmonary vein, left atrium, mitral valve, left ventricle, aortic valve, aorta, body
Innermost layer (connective tissue)
Tunica intima
What causes ventricle contractions
Muscle fibers
Mitral valve is located where
Left side of the heart
What Carrie’s blood to the entire body
Aorta
