AV valves

Semi-lunar valves

Heart Murmers are

Backlfow from a valve not closing correctly

pulmonary veins carry

oxygenated blood to the heart

The aorta carries

oxygenated blood to the body

The vena cava carries

deoxygenated blood from body to heart

Systole

Contraction of the heart

Diastole

Relaxation of the heart

normal blood pressure

120/80

high blood pressure number

140/90

Hypertension

high blood pressure

conjestive heart failure

mini heart attacks- fluid in lungs

The left ventricle is

largest and strongest

pulmonary edema

fluid in the air sacs and bronchioles

lub dub

the sound made by the heart valves as they close.

AV Valves of the heart

Semilunar valves

AV node (atrioventricular node)

Conduction relay node between the atria and ventricles. Signal from the SA node travels through the AV node to the ventricles

SA node (sinoatrial node)

pacemaker of the heart, located in the right atrium, which causes atria to contract

Tachycardia

rapid heart rate

Bradycardia

slow heart rate (less than 60 bpm)

Electrocardiogram (ECG)

recording of the electrical changes that occur in the myocardium during a cardiac cycle

sphygmomanometer

blood pressure cuff

Artherosclerosis

Hardening and narrowing of the arteries due to buildup of cholesterol plaques
