Anatomy and Physiology of the Heart: Pericardium, Layers, Fluid, Valves, and Cardiac Cycle, Quizzes of Physiology

Definitions and terms related to the anatomy and physiology of the heart, including the heart's term and functions, the pericardium and its layers, the serous fluid, valve problems, and the cardiac cycle. Topics covered include the heart's term, the covering and wall of the heart, the pericardium, its double layers, the serous fluid, pericarditis, the three layers of the heart wall, heart flow, valve problems, the nodal system, and electrocardiography.

TERM 2

Covering and wall of the heart

DEFINITION 2

Pericardium, double layered sack

TERM 3

Parietal pericardium

DEFINITION 3

outer layer

TERM 4

Visceral pericardium

DEFINITION 4

inner layer

TERM 5

Serous Fluid

DEFINITION 5

lubrication and shock absorption

Pericarditis

Pericarditis is an inflammation of the pericardium. A

characteristic chest pain is often present.

TERM 7

Three Layers of the heart wall

DEFINITION 7

Epicardium- outter layerMyocardium- middle , muscle

thickest layerEndocardium- inner layer, continues with the

layers of the blood vessels

TERM 8

Heart flow

DEFINITION 8

Know the flow

TERM 9

Valve Problems

DEFINITION 9

Incompetent valves- do not close completelyValvular

stenosis- stiffened and close slowlyProlapsed- does not close

tightly.. usually the bicuspid turns inside out.

TERM 10

Nodal system/intrinsic

conduction

DEFINITION 10

it lies directly in the cardiac tissue and keeps the heart

beatingSinoatrial Node; SA the pace makers, located on the

superior portion of the atria, top down conductoinAtrioventricular

(AV) bundle also called the bundle of HIS - runs down the septum

and is insulated so it does not contract the muscles it

passesPurkinge fibers located at the bottom of the heart, and

contract from the bottom up, forcing blood up and out.,

3 stages in a cardiac cycle

mid to late diastole- heart is relaxing atria are fillingVentricular

Systole- ventricals are contracting, pressure increases, AV valves

close and similunar valves openduring this time atria are relaxing

and fillingthis stage ends when the ventricals relax and similunar

closeearly diastole- ventricals relax and pressure drops, av valves

are closed for a moment, when the pressure in the vetricals is

lower than atria the venticals fill with blood

TERM 17

Lub Sound

DEFINITION 17

AV snapping shut

TERM 18

Dub sound

DEFINITION 18

Similunar valves snapping shut

TERM 19

Murmmurs

DEFINITION 19

When blood is going over an obstical

TERM 20

Cardiac Output

DEFINITION 20

total volume of blood being pushed out by the heart = SVSV

= stroke volumeCO = SV X HR
