circultory review Flashcards
what are the 3 types of blood vessel and functions
arteries-pump blood away from heart
veins- pump blood to heart
capillary- exchange
what do capillaries exchange
gases and wastes
where is the sa and av node located
in right atrium
where is the tricuspid valve
between the right atrium and right ventricle
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
contraction of the right ventricle forces blood into the
pulmonary artery
blood pressure is the highest when
ventricle contract
the lymatic system consists of
valves and vessels
where are chordae tendineae
in ventricles
what blood vessel supplies the heart blood
coronary artery
where does lymph enter the veins
subclavin veins
