Name the locations that blood flows through starting at the Vena Cava
Vena Cava
Right Atrium
Tricuspid Valve
Right Ventricle
Pulmonic Valve
Pulmonary Artery
Lungs
Pulmonary Vein
Left Atrium
Bicuspid/Mitral Valve
Left Ventricle
Aortic Valve
Aorta
Arteries, arterioles, capillaries
Venules, veins
Arteriole blood is responsible for what?
Blood Pressure
Venous blood is stressed or unstressed?
Unstressed
Define systolic pressure:
Maximum pressure from left ventricular contraction
Define diastolic pressure:
Pressure created by elastic recoil of the aorta (ventricle relaxation and blood filling)
Pulse pressure:
(Difference btw. systolic and diastolic)
Blood Pressure:
Systolic/Diastolic Canine avg. 133/76
Mean arteriole pressure:
Diastolic pressure + 1/3 pulse pressure
ANP?
Artrial Natriuretic Peptide Hormone the gives up sodium to the urine in an effort to decrease blood pressure. Where sodium goes, water will follow which decreases blood volume= decrease in blood pressure. *ANP prevents blood volume overload in the right atrium
Systemic Circuit Components:
Pressure circuit
left heart, arteries, veins
blood to body
Pulmonary Circuit Components:
Volume circuit
low pressure
right heart, pulmonary arteries, capillaries, veins
blood to lungs
Stroke volume:
the amount of blood leaving the ventricle with each heart beat
T/F Venous return directly affects cardiac output
True
What is preload?
End Diastolic Volume. The blood volume in the ventricle after diastole
What is End systolic volume?
The blood volume in the ventricle after a contraction
