ATI TEAS SELF QUIZ:Cardiovascular
System Questions And Correct
Answers 2024
Name the 4 parts to the cardiovascular system - Correct Answer heart, blood vessels,
blood, and lymphatic system
is the cardiovascular system and open or closed system? - Correct Answer closed
what is cardiac tissue called - Correct Answer myocardium
what is the surrounding sac of the heart called? - Correct Answer Pericardium
the 4 chambers of the heart is divided by the? - Correct Answer median septum
What is the pulmonary system? - Correct Answer sends blood to lungs
What is the systemic system? - Correct Answer sends blood to the rest of the body
arteries have what kind of walls? - Correct Answer thick smooth muscle to withstand
pressure of a forceful heartbeat
Capillaries are how many cells thick? what happens here? - Correct Answer one cell
thick and allows for gas and nutrients to exchange to tissues and lungs
veins have valves - why? - Correct Answer to help blood move in the right direction and
prevent blood from flowing back
explain the Heart blood path including valves (start from superior and inferior vena
cava) - Correct Answer superior and inferior vena cava -> Right atrium -> tricuspid valve
-> right ventricle -> pulmonary valve -> pulmonary artery -> lungs -> pumonary veins ->
left atrium -> bicuspid valve (mitral valve) -> left ventricular -> aortic valve -> aortic ->
tissues -> superior and inferior vena cava
explain what happens when the atrium and ventricles contract - Correct Answer atria
contracts which fills the ventricles and ventricular contraction empties them forcing
circulation
What causes the right and left atria to contract? - Correct Answer the SA node
what is known as a pacemaker? - Correct Answer SA node
After the SA node what happens? - Correct Answer AV node and then the AV bundle
and then the purkinje fibers are sparked causing ventricles to contract
