BIOD 103 Module 5
Cardiovascular system function - answer get life-sustaining, oxygenated blood from the
heart to the tissues and rid the body of carbon dioxide and waste products
pericardium - answer fluid filled sac that surrounds the heart
endocardium - answer innermost layer of the heart
epicardium - answer outermost layer of the heart
myocardium - answer the thick middle layer of the heart wall composed of cardiac
muscle tissue
atria function - answer receiving stations for blood coming from the body to the heart
ventricles function - answer pump blood back out into body
bicuspid (mitral) valve - answer between left atrium and left ventricle
tricuspid valve - answer valve between the right atrium and the right ventricle
pulmonary semilunar valve - answerlocated between the right ventricle and the
pulmonary artery
aortic semilunar valve - answerlocated between the left ventricle and the aorta
arterial system - answerarteries, arterioles, capillaries
pulmonary artery - answerartery carrying oxygen-poor blood from the heart to the lungs
venous system - answerveins and venules
aorta - answerThe large arterial trunk that carries blood from the heart to be distributed
by branch arteries through the body
pulmonary veins - answerDeliver oxygen rich blood from the lungs to the left atrium
superior vena cava - answerreceives blood from the head and arms and chest and
empties into the right atrium of the heart
inferior vena cava - answercarries blood from lower regions of the body to right atrium
, 4 components of blood - answerred blood cells, white blood cells, platelets, plasma
red blood cells (erythrocytes) - answercarry oxygenated blood throughout the body
white blood cells (leukocytes) - answerserve as part of the body's immune system
fighting off infection, and other pathogens
plasma - answermostly comprised of water but also contains proteins, nutrients, waste
products, and gas
platelets - answerprevents blood from escaping through compromised vessels by
initiating the clotting process
cardiac cycle - answermovement of blood throughout the body
Sino-artrial node (SAN) - answerheart's natural pacemaker that jump starts the cardiac
cycle
diastole - answerresting period when the heart rests and fills with blood
systole - answerwork period when the heart contracts to pump blood into the arteries
aort/o - answeraorta
angi/o, vas/o - answervessel
arteri/o - answerartery
arteriol/o - answerarteriole
atri/o - answeratrium
ather/o - answeryellow plaque, fatty substance
cardi/o, coron/o - answerheart
ox/o, ox/i - answeroxygen
phleb/o, ven/o - answervein
pulmon/o - answerlung
scler/o - answerhardening
thromb/o - answerclot
