where is the bicuspid valve
in between of the left atrium and left ventricle
when does diastolic pressure occur
while ventricles are relaxing
where is blood velocity the slowest
in the capillary
what does the p wave in the EKG
atrial contraction
what is the QRS in the EKG
ventricular contractions
what is the t wave in the EKG
ventricular relaxion
what is known as the pacemaker
the sa node
what does the av node do
signals the ventricles to contract
which vessel transports blood through the kidneys
renal
which vessel transports blood through the leg
iliac
