Lab Quiz - Major blood vessels Flashcards
what three arteries branch out directly from the aorta?
Brachiocephalic trunk
left common carotid artery
left subclavian artery
what arteries branch out from the brachiocephalic trunk?
right common carotid artery
right subclavian artery
Even though arteries carry oxygenated blood away from the heart (red), why are some arteries colored blue?
they are colored blue when they are carrying deoxygenated blood away from the heart, and to the lungs.
what causes a new name for an artery/ vein?
every branch point starts a new name for arteries
every point of merged branches starts a new name for veins
Even though veins carry mostly carry deoxygenated blood (blue) towards the heart, why are some veins colored red?
they are red when they are carrying oxygenated blood from the lungs to the heart
what artery directly supplies blood to the kidneys
renal arteries
what three veins join to form the superior vena cava?
left and right subclavian veins + internal jugular merge to form 2 brachiocephalic veins, which then is merged to form the superior vena cava
where does the abdominal aorta end?
common iliac arteries
which vessel feeds the upper abdominal quadrants?
celiac trunk
which vessel is immediately below the celiac trunk?
superior mesenteric artery
which vessel feeds the pancreas and small intestine?
superior mesenteric artery
which vessel feeds the distal part of the large intestine?
inferior mesenteric artery
which is the widest vessel of the body?
inferior vena cava (it has to return blood from all the lower half of the body)
which vessels merge to form the inferior vena cava?
common iliac veins
which vessels merge to form the superior vena cava?
both right and left brachiocephalic veins
what two vessels merge to form the brachiocephalic vein?
internal jugular and subclavian veins
which vessels are responsible for transporting blood to lungs?
pulmonary trunk
pulmonary arteries
lobar arteries
what is the job of the lobar arteries?
to provide blood to each individual lobe
what vessel(s) dumps blood in the left atria of the heart? how many are there?
pulmonary veins
4 total (2 on left side and 2 on right)
Name the anatomical landmark where the thoracic aorta becomes the abdominal aorta
diaphragm
describe where the inferior vena cava starts and ends
it extends from the merge of common iliac veins and ends in the right atrium
the common carotid arteries carry blood to what region of the body?
carries blood up to the head
the brachiocephalic trunk is important for carrying blood to which side of the body?
right side of arm and right side of head
what is the name of this week’s lab session?
