The cardiovascular system Flashcards
Cardiovascular means
pertaining to the heart and blood vessels
The structures surrounding the heart
Pericardium
Paricardium is a
Double-walled membrane that surrounds the heart
The three walls of the heart and where they are located
Epicardium= external layer
Myocardium= middle layer
Endocardium= inner layer
Coronary vessels
Blood vessels that deliver blood to and take blood from the heart
Coronary occlusion means and can lead to
blockage of coronary vessels which may lead to ischemia which in tern can lead to necrosis
Ischemia
A deficiency in blood supply to an area
Necrosis meaning
Tissue death
Infract meaning
An area of necrosis caused by an interrupted blood supply
Artria
Superior chambers of the heart
Ventricles
Inferior chamber of the heart
Septum
A separating wall
Apex
The tip of the heart
Valve
Membranous fold
Arrythmia
Abnormal heart rythym
Systole
Contraction
Diastole
Relaxation
Asystole
Without contraction or lack of heart activity
Bradycardia
Abnormally slow heartbeat
Tachycardia
Abnormally fast heartbeat
Electrocardiogram
The record of electrical activity of the myocardium
Electrocardiography
The process of recording electrical activity of the heart
Auscultation
Listening to body sounds with a stethescope
Murmur
Abnormal sound associated with turbulent blood flow
Stenosis
Narrowing
Combining form for vessels
angi/o or vas/o
Lumen
Opening of blood vessels through which blood flows
Constriction
Narrowing the lumen
Dilation
Widening of the lumen
Arteries are
blood vessels that carry blood away from the heart
Smaller arteries are
arterioles
Capillaries are
Single cell thick vessels that connect the arterial and venous systems
Perfusion
Blood flow through tissue
Veins are
blood vessels that carry blood towards the heart
Blood tension is the
Tension exerted by blood on the arterial walls
Combining form for pressure or tension
tensi/o
Pulse is the
Rhythmic expansion and contraction of an artery produced by pressure
Sphygmomanometer measures
