Ch 11 Flashcards
Veins
Thinner walls than arteries and move deoxygenated blood toward the heart from the tissues.
Capillaries
Are the smallest vessels. They form the point of exchange for oxygen and nutrients into body cells and waste products coming from body cells.
*patent term means “open”
Two phases of the heart beat
Diastole & systole.
Diastole
Relaxation.
Systole
Contraction.
ECG or EKG
(Electrocardiogram) the record used to detect electrical changes in the heart muscle as the heart beats.
Blood pressure
The force that blood exerts on arterial walls. To measure blood pressure you use a sphygmomanometer.
Aorta
Largest artery in the body.
Arteriole
Small artery.
Co2
Waste gas released by body cells transported via veins to the heart and then lungs to exhalation.
Endocardium
Inner lining of the heart.
Pacemaker
Specialized nervous tissue in the right artrium that begins the heartbeat.
Pericardium
Double layered membrane surrounding the heart.
Pulmonary artery
Artery carting oxygen poor blood from the heart to the lungs.
Pulmonary circulation
Flow of blood from the heart to the lungs back to the heart.
Thrombus
Blood clot.
Venule
Small vein.
ANGI/o
Vessel.
Brachi/o
Arm.
Coron/o
Heart.
Cyan/o
Blue.
Myx/o
Mucus.
Phleb/o
Vein.
Sphygm/o
Pulse.
Steth/o
Chest.
Arrhythmia
Heart block.
CHF Congestive heart disease
The heart is unable to pump the required amount of blood.
CAD coronary artery disease
Atherosclerosis think fatty plaque thrombotic occlusion( non moving clot). Drug therapies for CAD nitrates, vasodilators, lowers BP.
ACS Acute coronary syndromes
Unable angina
Myocardial infarction.
Aneurysm
Ballooning of a blood vessel.
