right ventricle Ans- pumps deoxygenated blood to the lungs
tricuspid valve Ans- valve between the right atrium and the right ventricle
pulmonary artery Ans- Carries deoxygentated blood from the heart to the lungs
pulmonary veins Ans- carry the oxygenated blood from the lungs into the left atrium of the heart
left ventricle Ans- pumps oxygenated blood to the body
left atrium Ans- receives oxygenated blood from the lungs
right atrium Ans- Receives deoxygenated blood from the body
mitral (bicuspid) valve Ans- valve between the left atrium and the left ventricle.
SA node Ans- pacemaker of the heart, where normal electrical impulses begin
AV node Ans- region where electrical impulse in the heart is slowed to allow blood time to pass
from the atria to the ventricles
sympathetic nervous system Ans- flight or fight; speeds heart rate, dilates blood vessels in
muscle, increases respiratory speed and depth, constricts blood vessels in digestive system
parasympathetic Ans- feed and breed; slows heart & respiratory rate, constricts blood vessels in
muscles, dilates blood vessels in digestive system
cardiac output Ans- heart rate x stroke volume
stroke volume Ans- The amount of blood ejected from the heart with each ventricular
