What are blood vessels? - answer closed system of tubes that cary blood around body
What are arteries? - answer Blood vessels that carry blood away from the heart
How do arteries branch? - answer Branch into smaller vessels until they form capillary
beds
What occurs within capillary beds? - answerGas, nutrient, and waste exchange
How is blood drained from capillaries? - answerVia veins
What are veins? - answerBlood vessels that carry blood back to the heart
What is the systemic circuit? - answerCarries oxygenated blood from the left side of the
heart to the body and returns deoxygenated blood to the right side of the heart.
What is the coronary circuit? - answerDelivers oxygenated blood to the heart for
metabolic needs
What is the pulmonary circuit? - answerCarries deoxygenated blood from the right side
of the heart to the lungs, and returns oxygenated blood back to the left side of the heart
via the pulmonary veins.
What is the largest artery in the body? - answerThe Aorta
Where does the aorta originate, and what is it called? - answerThe left ventricle as the
Ascending Aorta
What does the ascending aorta become when it curves? - answerThe Aortic Arch
What are the three branches of the Aortic Arch? - answer-Brachiocephalic Artery
-Left Common Carotid Artery
-Left Subclavian Artery
Where is the brachiocephalic artery located? - answerTravels superiorly and to the right
near the clavicle
What 2 branches does the brachiocephalic artery branch into when traveling near the
clavicle? - answer-Right Subclavian Artery
-Right Common Carotid Artery
, What is the purpose of the Right Subclavian Artery and what does it branch into? -
answer-Supplies the upper limb
-Becomes Axillary Artery near axilla
What does the axillary artery branch into? - answerThe brachial artery and then the
radial and ulnar arteries
Where does the right common carotid artery travel and what does it branch into? -
answer-Travels in neck
-Splits into Internal Carotid Artery and External Carotid Artery
What does the Internal Carotid Artery supply? - answerThe brain
What does the External Carotid Artery supply? - answerThe face and scalp
What does the Left Common Carotid Artery branch into? - answerInternal and External
Carotid Arteries in the neck
Where does the Left Subclavian Artery serve? - answerSupplies the left upper limb
What does the Left Subclavian Artery branch into? - answerAxillary artery > brachial
artery > radial + ulnar arteries (but on the left side now)
Where does the arterial supply of the brain primarily come from? - answerInternal
Carotid Arteries and Basilar Artery
Where is the Basilar Artery located, and what is it derived from? - answer-Base of
brainstem
-Fusion of 2 branches of the Subclavian Arteries called the Vertebral Arteries
What do the Basilar Artery and the Internal Carotid Arteries form when entering the
brain? - answerThe Circle of Willis (aka Cerebral Arterial Circle)
What is the Circle of Willis composed of? - answerBranches of the basilar artery and the
internal carotid artery as well as a set of Anterior and Posterior Communicating Arteries.
What do the vessels of the Circle of Willis do? - answerThey provide alternate routes of
circulation to the brain in case if an artery supplying the brain gets blocked.
What do these vessels become after branching off from the Aortic Arch? -
answerThoracic Aorta
How does the Thoracic Aorta branch? - answerDescends through the thoracic cavity
posterior to the heart, then passes through the diaphragm, and becomes the Abdominal
Aorta
