left side of heart
side of the heart that pumps oxygenated blood out to the body
Aortic valve
valve that opens when the left ventricle contracts and closes when left ventricle relaxes
pulmonary artery
blood vessel that delivers deoxygenated blood to the lungs when the right ventricle contracts
inferior vena cava
large vein returning deoxygenated blood from the lower body to the heart
capillaries in body
where gas exchange (O2 and CO2)
tricuspid valve
valve that closes to prevent blood from re-entering the right atrium when the right ventricle contracts
red blood cells
cells that carry O2 and CO2
right side of the heart
side of the heart that pumps deoxygenated blood to the lungs
arteries
a pulse wave can be palpated over these vessels when the left ventricle contracts
true
the aorta contains oxygenated blood
false
the right atrium contains oxygenated blood
false
the pulmonary vein sends oxygenated blood to the lungs
pulmonary valve
valve that opens when the right ventricle contracts and closes when the right ventricle relaxes
mitral valve
valve that closes to prevent blood from re-entering the left atrium when the left ventricle contracts
aorta
large blood vessel through which blood is forced when the left ventricle contracts
veins
blood vessels all over the body that collect and return deoxygenated blood to the right side of the heart
pulmonary veins
blood vessels which return oxygenated blood from the lungs to the left atrium
left ventricle
part of the heart that works the hardest
right ventricle
pumps deoxygenated blood to the lungs to pick up oxygen
superior vena cava
blood vessel which returns deoxygenated blood from the upper body to the right atrium
false
the pulmonary artery sends oxygenated blood to the lungs
false
the superior vena cava returns oxygenated blood to the right atrium
correct blood flow
right ventricle to pulmonary artery, to the lungs, to the pulmonary veins to the left atrium, left ventricle and then aorta
O2
the right side of the heart pumps deoxygenated blood to the lungs to pick up
CO2
when blood from the right side of the heart goes to the lungs it drops off
normal pathway of electrical impulse
SA node to AV node to bundle of HIS to right and left bundle branches
Pulse
the muscular action of the heart can be measured by
Feel
palpation means to
Veins
this type of blood vessels has valves to promote blood flow to returning to the heart
Capillary
type of blood vessel allows the exchange of nutrients, oxygen, and waste products between the tissues and blood
pericardium
the serous membrane that surround the heart
endocardium
the layer of the heart that lines the chambers
tachycardia
a heart rate that is above 100 beats per minute
arteriosclerosis
hardening of the arteries
carry oxygen
the role of hemoglobin in the blood cells
between the right atrium and right ventricle
the tricuspid valve is located
ventricular fibrillation
quiver in an uncoordinated movement
120/80
normal range for blood pressure
mitral valve
the valve between the left atrium and left ventricle
P-wave signals
contraction of the atria
septum
the name of the structure that separates the heart into left and right
low in oxygen content
blood in right ventricle
arteries
they carry blood away from the heart
QRS complex
the ventricles contracting on an ECG
determine the electrical activity in the heart
Dr. Fixa Hart ordered an ECG for his patient experiencing chest pain, arrhythymia, and fluctuating blood pressure. Dr. Fixa Hart can expect to gain what knowledge from the ECG?
heart failure
a condition where the heart cannot pump blood efficiently
valve insufficiency
when a valve does not close all the way
atherosclerosis
a condition where plaque builds up inside the arteries
valve stenosis
when a valve does not open all the way
atrial fibrillation
a condition causing the atria to quiver
murmur
an abnormal heart sound
