The heart has two separate pumps: the left and the right pump. Where does the left side of the
heart pump blood to, and where does the right side of the heart pump blood to? - Answer -
The left side of the heart pumps blood to the systemically (i.e., body)
-Right side of the heart pumps blood to the lungs
What is oxygenated and deoxygenated blood? - Answer -oxygenated blood is filled with
oxygen from the lungs
-deoxygenated blood has had most of its oxygen removed and is returning to the lungs to
become oxygenated
What vessels carry oxygenated and deoxygenated blood in the pulmonary circuit? - Answer -
Arteries carry deoxygenated blood
-veins carry oxygenated blood
What vessels carry oxygenated and deoxygenated blood in the systemic circuit? - Answer -
arteries carry oxygenated blood
-veins carry deoxygenated blood
What are the 4 chambers of the heart? - Answer -right atria
-left atria
-right ventricle
-left ventricle
What vessels does the right ventricle pump blood into? - Answer -into the pulmonary trunk,
which leads to the pulmonary arteries
,What vessels does the left ventricle pump blood into? - Answer -into the aorta, which leads
to systemic arteries
What are the three vessels that deliver blood to the right atrium? - Answer -inferior vena
cava
-superior vena cava
-coronary sinus
What are the five vessels that emanate from the aorta? - Answer -right coronary arteries
-left coronary arteries
-left subclavian artery
-left common carotid artery
-left brachiocephalic artery
What is the name for the valve between the right atrium and right ventricle? - Answer
tricuspid valve (right AV valve)
What is the name for the valve between the left atrium and left ventricle? - Answer bicuspid
valve (left AV valve or mitral valve)
What is the name for the valve between the right ventricle and pulmonary trunk? - Answer
pulmonary semilunar valve (pulmonary valve or right semilunar valve)
What is the name of the valve between the left ventricle and the aorta? - Answer Aortic
semilunar valve (aortic valve or left semilunar valve)
What is the name for the wall between the atria? - Answer interatrial septum
What do the left and right coronary arteries supply blood to? - Answer -left coronary artery
supplies blood to the left side of the heart
-right coronary artery supplies blood to the right side of the heart
What vessel is located in the inter ventricular sulcus? - Answer -left anterior descending
(LAD) coronary artery
-supplies blood to the front of the left side of the heart
, Why is LAD called the widow maker? - Answer -Since the LAD carries fresh blood to the
heart, if it is blocked, the heart can die very fast.
What is atherosclerosis? - Answer -condition in which plaque builds up inside the arteries
What is thromboembolism? - Answer -a blood clot, which can occlude blood vessels and
cause stroke and myocardial infarction
What is the foreman ovale in a fetus' heart? - Answer -interatrial septum
-it is a shunt that allows blood to shuttle straight from the right atrium to the left atrium, since
lungs are not functional in a fetus
-if still present in adults known as "hole in the heart" and can cause problems for some people
since it leads to poor oxygen delivery to organs
What does foreman ovale become in adults? - Answer fossa ovalis
What is the ductus arterioles in a fetus' heart? - Answer -it's between the aortic arch and the
pulmonary trunk
-it shunts blood from the pulmonary trunk to the aortic arch, away from the lungs
What does ductus arterioles become in adults? - Answer ligamentum arteriosum
What are the 3 layers of the heart (innermost to outermost) - Answer -endocardium
-myocardium
-epicardium
Which layer is thicker in the left ventricle compared to right and why? - Answer -myocardium
is thicker in the left ventricle because it needs to pump blood to entire body and needs to
generate a considerable amount of force
-right only pumps blood 6 inches away to the lungs
