Cardiovascular Flashcards
Name the four chambers of the heart and where they are
Right Atrium and Right Ventricle
Left Atrium and Left ventricle
Name the 4 tubes into the heart
Vena Canva
Pulmonary Artery
Pulmonary Vein
Aorta
Which heart chambers are attached to which tubes?
Superior vena cava moves blood into the right atrium
Pulmonary Artery moves blood from the right ventricle
Which heart chamber is attached to pulmonary artery?
Pulmonary Artery moves blood from the right ventricle
Which heart chamber is attached to vena cava?
Superior vena cava moves blood into the right atrium
Which heart chamber is attached to pulmonary vein?
left atrium
Which heart chamber is attached to aorta?
left ventricle
What are the valves between the atriums and ventricles?
Right= Tricuspid valve Left= mitral valve
What valve separates the right ventricle and pulmonary artery?
Pulmonary valve
What valve separates the left ventricle and aorta?
Aortic valve
What are the 3 types of cardiac muscle?
Atrial
Ventricular
Excitatory and conductive
How are atrial and ventricular similar to skeletal muscle?
They contract similarly but duration of contraction is longer
The heart muscle has what feature?
Myogenic
Describe the cardiac function graph with mV and time.
at -100 mv Purkinje fiber the lowest, +20 peaks then plateus ( flat top of peak)
Same shape for ventriuclar muscle but at lower mV. -80 still peaking at 20
What structural feature of muscles allows excitation to spread?
Gap junctions
