Name the locations that blood flows through starting at the Vena Cava
Arteries, arterioles, capillaries
Arteriole blood is responsible for what?
Venous blood is stressed or 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)
(Difference btw. systolic and diastolic)
Systolic/Diastolic Canine avg. 133/76
Mean arteriole pressure:
Diastolic pressure + 1/3 pulse pressure
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:
left heart, arteries, veins
blood to body
Pulmonary Circuit Components:
right heart, pulmonary arteries, capillaries, veins
blood to lungs
the amount of blood leaving the ventricle with each heart beat
T/F Venous return directly affects cardiac output
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
