What side of the heart pumps blood to the
lungs? What does this side do?
Right atrium and ventricle work to pump oxygen poor blood to the lungsThe right atria receives its supply of oxygen-poor blood from the two largest veins in the body.The right ventricle pumps oxygen-poor blood in through the pulmonary artery. TERM 2
What side of the heart pumps blood to the
body? What does this side do?
DEFINITION 2 Left atrium and ventricle combine to pump blood to the bodyThe left atria receives blood that has been oxygenated in the lungs from the pulmonary artery.The left ventricle pumps oxygenated blood to the body through the aorta. TERM 3

DEFINITION 4 Pulmonary Valve TERM 5
What valve is between the left atrium and the
left ventricle?
DEFINITION 5 Mitral valve
What valve is between the left ventricle and
the aorta?
Aortic Valve TERM 7
What is the thin membrane that lines the
interior of the heart?
DEFINITION 7 Endocardium TERM 8
What is the middle layer of the heart that is
the thickest layer and is also called the
muscle?
DEFINITION 8 Myocardium TERM 9
What is the thin sac the heart sits in and that
contains fluid?
DEFINITION 9 Pericardium TERM 10
Conduction
DEFINITION 10 sets the heart rate and allows the upper and lower champers to communicate with each other so they can function in a coordinated fashionSA node causes the atrium to contract and pump blood into the ventricle. Then the impulse passes through to the AV node which causes the muscle to contract and to pump blood to the lungs and the body.
cardiac risks for tobacco?
rise in heart rate rise in BP because of vasoconstriction high levels of carbon monoxide: reduces the amount of oxygen blood can carry triples risk of dying for heart disease major cause of stroke increase blood cholesterol levels Buerger's Disease (Throboangitis Obliterans) TERM 17
