Fun Facts
100

large vein brings deoxygenated blood from the upper body into the right atrium

superior venacava

100
Number of chambers in the heart

4

100

 blood vessel carries oxygenated blood from the lungs back to the left atrium

pulmonary veins

100

Arteries carry blood ___ from the heart, while veins carry blood ___ the heart

away, toward

100

"lub-dup" sound of a heartbeat is caused by the opening and closing of these

valves

200

chamber receives deoxygenated blood from the body

right atrium

200

Muscular middle layer of the heart

myocardium

200

valve between the left atrium and left ventricle

bicuspid/mitral valve

200

exchange of oxygen, nutrients, and waste products between blood and body cells occurs in these smallest blood vessels

capillaries

200

condition occurs when blood flow to the heart muscle is blocked or significantly reduced

heart attack

300

valve between the right atrium and right ventricle

tricuspid

300
protective fluid filled sac surrounding the heart

pericardium

300

chamber of the heart has the thickest, most muscular walls

left ventricle

300

circuit specifically refers to the pathway of blood traveling to and from the lungs to get oxygen

pulmonary circulation

300

normal resting heart rate (bpm) is generally considered to be in this range

60-100 bpm

400

 After leaving the right ventricle, blood passes through

pulmonary valve
400

body's natural pacemaker, electrical pathway for heart

sinoatrial node

400

After leaving the left ventricle, blood enters the

aortic valve

400

Veins contain these structures to ensure blood, which is under lower pressure, flows in only one direction toward the heart

valves

400

measure represents the force needed for your heart to pump blood through the arteries

blood pressure

500

the only artery in the body that carries deoxygenated blood

pulmonary artery

500

Anchor the atrioventricular valves to the walls of the ventricles to prevent backflow

chordae tendineae

500

large artery then distributes oxygenated blood to the systemic circuit of the body

aorta

500

a blood vessel's diameter increases in size, this term is used to describe the action

vasodilation

500

condition results from the buildup of fatty substances, or plaque, in the coronary arteries

coronary artery disease
