Once blood leaves the heart, it flows through two circulatory systems which are the -
Answer-Pulmonary and Systemic
Which artery is an exception and carries deoxygenated blood - Answer-Pulmonary
Arteries
Which vein is an exception and carries oxygenated blood - Answer-Pulmonary Veins
The capillaries provide _________ to the tissues of the body. - Answer-Oxygen
What helps determine pressure within a blood vessel? - Answer-It's diamater
The autonomic nervous system plays a major role in controlling - Answer-Vessel
diameter
The sympathetic nervous system prepares the body to expend energy which allows the
blood vessels to - Answer-Constrict
The parasympathetic nervous system allows blood vessels to return to a - Answer-
Relaxed state (homeostasis)
The heart contracts and ejects blood through an estimated _____________ miles of
blood vessels - Answer-75,000
The left side of the heart is the pump for the - Answer-Systemic circulation (pumps
oxygenated blood from the lungs out into the vessels)
The right side of the heart is the pump for the - Answer-Pulmonary circulation (receives
deoxygenated blood and sends it to the lungs for oxygenation)
The Sinoartial Node, Atrioventricular Node, Atrioventricular Bundle, Right and left
bundle branches and the conduction myofibers are apart of this system - Answer-The
conduction system
Systole (contraction) and diastole (relaxation) of both atria, rapidly followed by the
systole and diastole of both ventricles are apart of which cycle - Answer-Cardiac
, The sound of the heart comes primary from the ______________ in blood flow caused
by the closure of the valves - Answer-Turbulence
The first heart sound (lub) is created by blood turbulence associated with the closing of
the _______________ valves soon after ventricular systole begins - Answer-
Atrioventricular
Deoxygenated blood from the upper body drains into the right atrium through the -
Answer-Superior vena cava
Blood draining from the lower body flows into the right atrium through the - Answer-
Inferior vena cava
Blood leaving the right atrium pass through the tricuspid valve, into the right ventricle
which is the most - Answer-Anterior chamber of the heart
The tricuspid valve consists of _______ __________ held in pace by chordate
tendineae - Answer-Three cusps (leaflets)
These muscles originate from the internal wall of the right ventricle. - Answer-Papillary
The valve cusps, chordae tendineae and papillary muscles prevent the valve from -
Answer-"Blowing out" or leaking under pressure
Blood flows from the pulmonary valve (has three cusps) and passes through the
__________ _________ to get to the lungs. - Answer-Pulminary arteries
The simultaneous closing of the mitral and tricuspid valves and the opening of the
pulmonary valve crest the - Answer-First heart sound
Term that refers to any time the heart is not getting enough oxygen (cardiac
compromise). - Answer-Acute Coronary Syndrome (ACS)
A decrease in certain elements of the blood, especially red cells and hemoglobin. -
Answer-Anemia (lack of normal red blood cells)
Pain in the chest occurring when blood supply to the heart is reduced and a portion of
the heart is not receiving enough oxygen. - Answer-Angina Pectoris
Condition in which the heart ceased generating electrical impulses commonly called
flatline (no electric impulses). - Answer-Asystole
Valves that are located between the atrium and the ventricle, specifically the tricuspid
and mitral (bicuspid) valves. - Answer-Atrioventricular valves
Which valves allow blood to flow back into the atria? - Answer-Tricuspid and bicuspid
