10-20 ml
Where are papillary muscles located? Attached via the
ventricles
chordae tendinae
Pericardium is what type of tissue
connective tissue
Blood vessels can be categorized into what (3)
Conducting
Distributing/collecting
Functioning
Conducting vessels include what type of arteries and veins
elastic arteries
great veins
Conducting vessels are concerned with what task?
Conducting o2 blood out of heart and deoxy blood back into heart
Conducting vessels (4)
Aorta
IVC
common iliac arteries
common iliac veins
What type of vessels are found more distally?
Distributing and collecting
Distributing and collecting vessels are more (muscular or elastic)
Muscular
Distributing arteries vary in muscle wall amount based on
The control of blood supply to the area that they supply
What is a functioning vesel
capillaries (exhcange of nutrients, O2, waste, CO2)
Blood flow is influenced by (4)
cardiac function
elasticity of walls
Tone of smooth muscle
millions of branching vessels
Tunica externa is also called
adventia
Coapt means
collapse
Most common complication of impaired cardiac function
Heart failure
What is a heart attack
Clot in coronary artery blocking blood flow to the heart
Stroke is caused by
Brain not getting enough blood, brain tissue dies
What is an aneurysm
Bulge in artery wall (anywhere)
Ruptured aneurysm causes
Internal bleeding or
clot dislodges and blocks artery
What is periphery artery disease?
Term for leg pain caused by “ “
Extremity muscles not getting enough O2 to perform during exercise.
Clotication is leg pain, symptom of periphery artery disease
Cardiac arrest
Sudden loss of function in the heart, breathing and consciousness
3 symptoms of CVD
Chest pain
Shortness of breath
Fainting
What is heart arrhythmia
