Arteries
the vessels that lead away from the heart
Veins
have thinner walls than arteries and move deoxygenated blood toward the heart
Capillaries
are the smallest vessels. They transport blood, nutrients and oxygen to cells in your organs and body systems.
Tricuspid valve (cusps are flaps of the valves)
between the right atrium and right ventricle
Pulmonary valve
between the right ventricle and pulmonary artery
Mitral valve
between the left atrium and left ventricle
Aortic valve
between the left atrium and aorta
Diastole
relaxation
Systole
contraction
lubb
closure of the tricuspid and mitral valves at the beginning of systole
dubb
closure of the aortic and pulmonary valves at the end of systole
murmur
an abnormal heart sound caused by improper valve closure
Sinoatrial node (SA node)
the pacemaker of the heart
Pacemaker
origin of electrical impulse causing walls of the atria to contract and force blood into the ventricles (ending diastole)
Atrioventricular node (AV node)
This sends the excitation wave to a bundle of specialized fibers called the atrioventricular bundle or Bundle of His
ECG or EKG (electrocardiogram)
The record used to detect electrical changes in heart muscle as the heart beats
P wave
spread of excitation wave over the atria just before contraction
QRS wave
spread of excitation wave over the ventricles as the ventricles contract
T wave
electrical recovery and relaxation of ventricles
Blood pressure
The force that blood exerts on arterial walls (measured using a sphygmomanometer). Expressed as a fraction systolic pressure/diastolic pressure.
