tubelike structures that carry blood throughout the body
A blood vessel that carries blood away from the heart
Blood vessels that carry blood back to the heart
Microscopic vessel through which exchanges take place between the blood and cells of the body. Walls are only one cell thick
small vessels that receive blood from the arteries
small vessels that gather blood from the capillaries into the veins
coronary artery disease
atherosclerosis of the coronary arteries that reduces the blood supply to the heart muscle
condition in which fatty deposits called plaque build up on the inner walls of the arteries
congestive heart failure
A condition resulting from the heart's inability to pump out all the blood that returns to it; blood backs up in the veins leading to the heart, causing an accumulation of fluid in various parts of the body
sudden blockage of an artery, resulting in dead tissue
CPR (cardiopulmonary resuscitation)
refers to medical procedures used when a person's heart and lungs have stopped working
automated external defibrillator
high blood pressure. caused by high salt intake, or kidney disease
systolic blood pressure
the pressure created in the arteries when the left ventricle contracts and forces blood out into circulation
diastolic blood pressure
the pressure remaining in the arteries when the left ventricle of the heart is relaxed and refilling
fluid in the air sacs and bronchioles usually caused by failure of the heart to pump enough blood to and from lungs
chest pain that results when the heart does not get enough oxygen
an inadequate blood supply to an organ or part of the body, especially the heart muscles.
the occlusion of one or more coronary arteries caused by plaque buildup (heart attack)
Abnormal heart rhythm
the rapid, irregular, and useless contractions of the ventricles
a very rapid heartbeat that begins within the ventricles
slow heart rate below 60bpm
fast heart rate above 100bpm
A state in which not enough oxygen is delivered to the tissues of the body, caused by low output of blood from the heart. It can be a severe complication of a large acute myocardial infarction, as well as other conditions.
sudden cardiac arrest
Occurs when the heart develops an abnormal rhythm and can't pump blood
a condition in which the heart has ceased generating electrical impulses. Commonly called flatline
stationary blood clot
A clot that breaks lose and travels through the bloodstream.
deep vein thrombosis
blood clot forms in a large vein, usually in a lower limb
A blood clot that breaks off from a large vein and travels to the blood vessels of the lung, causing obstruction of blood flow.
inflammation of the membrane surrounding the heart
A weakness in the wall of the aorta that makes it susceptible to rupture.
ballooning of a weakened portion of an arterial wall
a disease of the arteries characterized by the deposition of plaques of fatty material on their inner walls.
