- blood
- isch
- reduced
- aorta
- largest artery in the body, carries blood from the left side of the heart to everywhere
- atria
- the upper chambers of the blood, collects the blood and fills it up
- ventricles
- two lower chambers, right sends blood to the lungs, left passes oxiginated blood to the body. they simultaneously contract
- artery
- blood vessile, carries blood away from the heart
- vein
- carries blood back to the heart
- coronary arteries
-
vessel that carries blood from the aorta to the heart.
major arteries: left and right coronary arteries - sino artial (sa) node/ pacemaker
- the in the upper chamber of the heart that sends electric impulses thru the heart to make the heart pump
- atrio-ventricular node
- a cluster of nerve cells in between the right and left nodes of the atrium, carry signals from the atria to the ventricles
- pulse generator
- contains the electroncs and the battery of the pacemaker
- defibrillator
- an internal or external device that gives a shock when it sences irregular heartbeats
- sensor
- the part of the pacemaker that sences the body's need for blood flow
- endocardia
- inner lining of the heart
- epicardial
- the outter lining of the heart
-
tachyarrhythmias
(tack yar hi ta mias) - abnormally fast heart rythm
- synus rhythm
- regular rhythm of the heart
- plaque
- fat deposits that cause narrowing blood vessels
- pleura
- 2 walled sacs of membrane that cover the lungs
- systole
- when ventricls contract
- diastole
- when ventricls relax
- 3 types of cardio vascular system
- no circiluatory (artrapods); open circiluatory (flat worm); closed circiluatory (humans)

- coronary artery disease (CAD)
- when the coronary artries harden or narrow due to plaque
- arrhythmia
-
irregular or abnormal heartbeat
aka dysrhythmia - congenital heart defect
- defect in one or more structure of the heart of blood vessels
- cardiomyopathies
- abnormally enlarged, tick or stiff heart.
- pericarditis
- inflammation of the lining of the heart
- atherscloriss
- hardening of the artries
- hypertension
- high blood pressure
- aneurysm
- abnromal bulge in the blood vessel.
- atherecotmy
- a procedure for removing plaque
- bypass surgery
- surgery done when the artery is too clogged, a vein from the leg is used
- ace inhibitors
- cause the blood vessels to enlarge and reduce blood pressure
-
electrocardiogram
ECG or EKG - measures the electrical activity fo the heartbeat
