anatomy

Question 1

where do coronary blood vessels arise from

Answer 1

just superior to aortic valve; roughly off right cusp and left cusp

Question 2

what are the 3 cornorary vessels and where are they located

Answer 2

right coronary artery (right cusp; right ventricle); left anterior descending (left cusp; front; septum/left ventricle); left circumflex (left cusp; aound left ventricle)

Question 3

why do the 3 coronary vessels branch

Answer 3

to ensure blood reaches every cell

Question 4

where do the coronary veins conjugate

Answer 4

coronary sinus at back of heart

Question 5

where does the blood from the coronary sinus enter

Answer 5

right atrium

Question 6

veins of coronary circulation

Answer 6

anterior interventricular vein, anterior veins, great cardiac veins, small cardiac veins, right marginal vein, middle cardiac vein

Question 7

organ care system: which side is airtight

Answer 7

right side (pulmonary)

Question 8

organ care system: vessels

Answer 8

vena cava clamped; blood enters via pulmonary vein and leaves via pulmonary artery

Question 9

organ care system: blood to coronary veins

Answer 9

blood also pumped into aorta so hits aortic valve; pushed into coronary arteries to maintain myocardium function

Question 10

route of drainage vent placed into apex/left ventricle

Answer 10

vena cavae → left atria → mitral valve → left ventricle; removes blood from left ventricle
