Concept Map: 08 Cardiovascular System Adriana Mireles Period:6
Anatomy of the heart (including all chambers, and valves)
Heart contains
4 chambers
:
Ventricles:
The 2 lower chambers
Atria:
The 2 upper chambers
Heart contains
4 values:
Tricuspid Value
The
right AV
have cusps to which
chordae tendinae
attach
Bicuspid (Mitral):
The
left AV
have cusps to which
chordae tendinae
attach
Pulmonary Semilunar
Valve
Prevents
backflow
of blood into the
right ventricle
Aortic Semilunar Valve:
Prevents
backflow
of blood into the
left ventricle
Structural and functional differences between blood vessel types (arteries, veins,
capillaries)
Structural
Veins
Has the same three layers as the arteries only difference is that the muscle has thinner layer and has flap like values
it also has lumen which is a vein that is larger than that of an artery
Capillaries
Are blood vessels with the smallest diameter
Arteries
Consist of 3 layers:
Tunica Media
Thick middle layer, composed of smooth muscle
Tunica Externa
Outermost connective tissue layer thats relatively thin and attaches the artery to surrounding tissues
Tunica Interna
Innermost endothelial layer composed of simple squamous epithelum that creates a smooth surface that prevents clots
Functional
Veins
Wall of veins also has flap like values that prevent backflow of blood
Capillaries
Connects with small arterioles to small venules and is consit only of a layer of endothelium through, which substances are exchanged with tissue cells
Arteries
Sympathetic stimulation causes muscle contraction which results to vasoconstriction of arteries
Also when vasomotor impulses are inhibited the results will be vasodilation
Sympathetic controls for arteries and arterioles are usedto regulate blood flow and blood pressure (BP)
Wall of arterioles also get thinner as they approach the capillaries
Vital signs (BP and Pulse)

Major functions of the cardiovascular system
Layers of the heart
The heart is composed of 3 layers
Mycocardium:
The
middle layer
consist of cardiac muscle and is
thickest layer
of the heart wall that pumps blood out of heart chambers.
Endocardium:
The
inner layer
; made up of connective tissue and epithelium; continuous with the endotheliem of major vessels joining the heart that contains the
Purkinje Fibers
Epicardium (Visceral Pericardium):
The
outermost layer
, a serious membrane made up of connective tissue and epithellum, which
decreases
friction in the heart.
Disorders of the cardiovascular system
Cardiac cycle and the ECG
Cardiac Cycle
Then the ventricles contract (called ventricles sys
First the atria contract (called atrial systole), while ventricles relax (called ventricular diastole)
Major blood vessels (names arteries and veins)
