Chapter 6 pt 2 Cardiovascular System

aneurysm

• a localized weak spot or balloon-like enlargement of the wall of an artery
• Divides the right and left chambers of the heart
• carry blood away from the heart
• Blood vessels that carry blood back to the heart

angina

• an abnormal sound from the heart produced by defects in the chambers or valves
• disease of the heart muscle
• chest pain
• carries blood from lower regions of the body to right atrium

angiogram

• record of a vessel
• heart attack; death of myocardial tissue (infarction) caused by ischemia (loss of blood flow)
• carries blood from lower regions of the body to right atrium
• contraction phase of the heartbeat

anticoagulant

• artery carrying oxygen-poor blood from the heart to the lungs
• Beat of the heart as felt through the walls of the arteries.
• an abnormal sound from the heart produced by defects in the chambers or valves
• prevents blood clotting

Aorta

• Largest artery in the body
• receives oxygenated blood from the lungs
• relaxation phase of the heartbeat
• contraction phase of the heartbeat

aortic semilunar valve

• between left ventricle and aorta
• a localized weak spot or balloon-like enlargement of the wall of an artery
• hardening of the arteries
• Largest artery in the body

Arrythmia

• the use of electrical shock to restore the heart's normal rhythm
• Divides the right and left chambers of the heart
• Abnormal heart rhythm
• inflammation of the inner lining of the heart

Arteries

• a localized weak spot or balloon-like enlargement of the wall of an artery
• carry blood away from the heart
• an abnormal sound from the heart produced by defects in the chambers or valves
• blood pressure cuff

Arterioles

• Beat of the heart as felt through the walls of the arteries.
• Divides the right and left chambers of the heart
• contraction phase of the heartbeat
• smallest arteries

arteriosclerosis

• Membrane surrounding the heart
• hardening of the arteries
• Abnormal heart rhythm
• prevents blood clotting
