Pathway Of Blood Right
large vein brings deoxygenated blood from the upper body into the right atrium
superior venacava
4
blood vessel carries oxygenated blood from the lungs back to the left atrium
pulmonary veins
Arteries carry blood ___ from the heart, while veins carry blood ___ the heart
away, toward
"lub-dup" sound of a heartbeat is caused by the opening and closing of these
valves
chamber receives deoxygenated blood from the body
right atrium
Muscular middle layer of the heart
myocardium
valve between the left atrium and left ventricle
bicuspid/mitral valve
exchange of oxygen, nutrients, and waste products between blood and body cells occurs in these smallest blood vessels
capillaries
condition occurs when blood flow to the heart muscle is blocked or significantly reduced
heart attack
valve between the right atrium and right ventricle
tricuspid
pericardium
chamber of the heart has the thickest, most muscular walls
left ventricle
circuit specifically refers to the pathway of blood traveling to and from the lungs to get oxygen
pulmonary circulation
normal resting heart rate (bpm) is generally considered to be in this range
60-100 bpm
After leaving the right ventricle, blood passes through
body's natural pacemaker, electrical pathway for heart
sinoatrial node
After leaving the left ventricle, blood enters the
aortic valve
Veins contain these structures to ensure blood, which is under lower pressure, flows in only one direction toward the heart
valves
measure represents the force needed for your heart to pump blood through the arteries
blood pressure
the only artery in the body that carries deoxygenated blood
pulmonary artery
Anchor the atrioventricular valves to the walls of the ventricles to prevent backflow
chordae tendineae
large artery then distributes oxygenated blood to the systemic circuit of the body
aorta
a blood vessel's diameter increases in size, this term is used to describe the action
vasodilation
condition results from the buildup of fatty substances, or plaque, in the coronary arteries
coronary artery disease
