The heart is considered a _______________.
Transport system consisting of two side by side pumps.
The right side of the heart ________________.
Receives oxygen-poor blood from tissues/ IT pumps blood to lungs to get rid of CO2, pick up O2, via PULMONARY CIRCUIT
The left side of the heart _______________
receives OXYGENATED blood from lungs, and pumps blood to body tissues via SYSTEMIC CIRCUIT
When the blood leaves the Left side of the heart it is in _____________.
Systemic circuit
The heart has _______ receiving chambers, and are called....
2, Right Atrium/Left Atrium
The right atrium receives blood from __________.
The systemic Circuit

Pumping chambers of the heart are ________
Right Ventricle/left ventricle
The part of the heart that pumps blood through the pulmonary circuit
Right ventricle
The part of the heart that pumps blood through the systemic circuit
the left ventricle
Part of the heart that Receives blood returning from systematic circuit
Right atrium

______________ is palpated between fifth and sixth rubs, just below the left nipple
APICAL IMPULSE
The covering of the heart is __________
Pericardium
The pericardium is double walled sac, that ________________
protects and anchors to surrounding structures and prevents overfilling.
This part of the pericardium lines the internal surface of fibrous pericardium.
PARIETAL LAYER
The Epicardium is also called the ____________ layer.
VISCERAL LAYER
This layer of the heart looks shiny, and is on the external surface of the heart
epicardium (VISCERAL LAYER)
The pericardial cavity of the pericardium has thin fluid and does this _______________
decreases fluid
This part of the heart protects from friction __________
serous pericardium
Inflammation of the pericardium is called ______________
PERICARDITIS
_______________________ makes a creaking sound heard with a stethoscope and roughens membrane surfaces.
PERICARDIAL FRICTION RUB
Excess fluid sometimes compresses heart - and leads to limited pumping ability
CARDIAC TAMPONADE
Three layers of the heart wall _______________________, __________________, ____________________.
Epicardium, Myocardium, Endocardium.
The _____________ is the visceral layer of the serous pericardium.
Epicardium
A spiral bundle of contractile cardiac muscle cell ______________
MYOCARDIUM.
This layer of the heart wall crisscrosses, interlaces layer of connective tissue, anchors cardiac muscle fibers, supports great vessels and valves, limits spread of action potentials to specific paths.
Myocardium
