Name the 4 parts to the cardiovascular system - Correct ANS: heart,
blood vessels, blood, and lymphatic system
is the cardiovascular system and open or closed system? - Correct ANS:
closed
what is cardiac tissue called - Correct ANS: myocardium
what is the surrounding sac of the heart called? - Correct ANS:
Pericardium
the 4 chambers of the heart is divided by the? - Correct ANS: median
septum
What is the pulmonary system? - Correct ANS: sends blood to lungs
What is the systemic system? - Correct ANS: sends blood to the rest of
the body
, arteries have what kind of walls? - Correct ANS: thick smooth muscle to
withstand pressure of a forceful heartbeat
Capillaries are how many cells thick? what happens here? - Correct
ANS: one cell thick and allows for gas and nutrients to exchange to
tissues and lungs
veins have valves - why? - Correct ANS: 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 ANS: superior and inferior vena cava ->
Right atrium -> tricuspid valve -> right ventricle -> pulmonary valve ->
pulmonary artery -> lungs -> pulmonary 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
ANS: atria contracts which fills the ventricles and ventricular
contraction empties them forcing circulation
