Lab 2 - Heart anatomy, cardiovascular dynamics and physiology
What are the layers of the pericardium starting from the outside?
Parietal Serous Pericardium
Paricardial Cavity filled with serous fluid
Visceral Serous Paricardium
What are the wall layers starting from the outside?
Epicardium = visceral layer of pericardium
Myocardium (muscle layer)
What are the 4 chambers of the heart?
What are the 2 valve groups in the heart and what are the 4 valves?
Atrioventricular Valves - Tricuspid valve, Bicuspid valve
Semilunar Valves - Pulmonary semilunar, Aortic sumilunar
Trace the path of electricity conduction in the heart.
Sinatrial pacemaker node
Purkimjy Fibers (L/R)
Assign each term to its respective side of the heart.
Less developed muscle
Well developed muscle
Right - passive, less developed muscle, collects blood
Left - active, well developed muscle, pumps blood
What are the properties of arteries and veins?
Arteries - elastic, high pressure
Veins - inelastic, low pressure
Trace a blood cell through the cardiovascular system, starting with systemic circulation.
Superior/Inferior Vena Cava
Pulmonary Semilunar Valve
Aortic Semilunar Valve
What is Poiseulle's Eqn?
Why is vessel radius a more important factor in controlling blood flow than vessel length?
Once growth ceases, length does not change.
What is diastole?
What is systole?
What is cardiac output?
Amount of blood each ventricle pumps per minute
What is Starling's Law?
When the rate at which blood returns to the heart changes, the heart will adjust its output to match the change in inflow.
Change in inflow = change in outflow
What is stroke volume?
Amount of blood pumped to the body per contraction per ventricle
