which blood vessel is a branch off the pulmonary trunk
pulmonary artery
the fibrous skeleton of the heart is a ________ of electricity
nonconductor
functions of the fibrous skeleton
- anchors the cardiocytes and give them something to pull against
- provides structural support for the heart
- provides electrical insulation between the atria and ventricles

fibrous
a fibrous cord that attaches the pulmonary trunk to the aortic arch is the
ligamentum arteriosum
what are the internal ridges of myocardium found in the right atrium and auricle
pectinate muscles
what describes the location of the right atrium
the right atrium is superior to the right ventricle
which describes the right ventricle of the heart
the right ventricle is inferior to the right atrium
pulmonary arteries are branches of the
pulmonary trunk
what is the location of the left ventricle
it is inferior to the left atrium
the lower chambers of the heart that pump blood to the lungs and to the body are the
ventricles
the thick-walled inferior chambers of the heart that pump blood into the arteries are called
