The Vascular System Part 2 Flashcards
describe the IMPORTANT DIFFERENCES between ARTERIES and VEINS
ARTERIES:
- they RUN DEEP
VEINS:
- run BOTH DEEP + SUPERFICIAL
DEEP VEINS;
have the same name as their CORRESPONDING ARTERY
SUPERFICIAL VEINS;
they do NOT share the same name with their corresponding artery
describe VENOUS PATHWAYS
- much more INTERCONNECTED
- have more than one name - can be harder to FLOW
what are the specific VENOUS DRAINAGE SYSTEMS for the BRAIN and DIGESTIVE SYSTEMS?
- BRAIN: DURAL VENOUS SINUSES
- DIGESTIVE SYS: HEPATIC PORTAL SYSTEM (perfuses through the liver before RETURNING to the HEART)
definition of PULMONARY CIRCULATION
helps with carrying DEOXYGENATED BLOOD AWAY from the HEART into the LUNGS and RETURNS OXYGENATED BLOOD back into the heart
which arteries supply the MYOCARDIUM with oxygen?
- RIGHT CORONARY ARTERY
- LEFT CORONARY ARTERY
what are the BRANCHES of the RIGHT CORONARY ARTERY?
- POSTERIOR INTERVENTRICULAR/DESCENDING ARTERY
- MARGINAL ARTERY
what are the BRANCHES of the LEFT CORONARY ARTERY?
- ANTERIOR INTERVENTRICULAR/DESCENDING ARTERY
- CIRCUMFLEX ARTERY
what are the AORTIC ARCH BRANCHES? and what parts of the body do they SUPPLY?
AORTIC ARCH BRANCHES:
- RIGHT BRACHIOCEPHALIC ARTERY
- LEFT COMMON CAROTID ARTERY
- LEFT SUBCLAVIAN ARTERY
supplies our UPPER BODY, ARMS, HEAD, and the NECK
what are the MAJOR SUBCLAVIAN BRANCHES? and what do they SUPPLY (D)?
- L/R AXILLARY ARTERIES (upper limb)
- L/R BRACHIAL ARTERIES (upper arm, forearm, elbow)
- L/R RADIAL + ULNAR ARTERIES (forearm, wrist, hand)
- L/R DIGITAL ARTERIES (phalanges, fingers)
supplies the UPPER LIMBS
what are the MAJOR (RIGHT) BRACHIOCEPHALIC BRANCHES and what do they SUPPLY ?
REMEMBER THERE IS NO LEFT BRACHIOCEPHALIC TRUNK!!!
- **the RIGHT BRACHIOCEPHALIC BRANCH leads into our RIGHT SUBCLAVIAN ARTERY
MAJOR (RIGHT) BRACHIOCEPHALIC BRANCHES:
- L/R COMMON CAROTID
(supplies the HEAD AND NECK)
has other TWO-SUBDIVISIONS;
- L/R EXTERNAL CAROTID
(supplies the HEAD–face, scalp, skull, and the meninges) - L/R INTERNAL CAROTID
(supplies the brain)
what are the MAJOR SUBCLAVIAN BRANCHES and what do they SUPPLY?
- VERTEBRAL ARTERY
- BASILAR ARTERY
supplies the HEAD and NECK
- often found BELOW the CLAVICLES
where does the BASILAR ARTERY supply to, does it have any type of SPECIAL BRANCHING?
BASILAR ARTERY:
- supplies into the BRAIN–and supplies blood to the CEREBROVASCULAR CIRCULATION
- ***creation of the CEREBRAL ARTERIAL CIRCLE (CIRCLE OF WILLIS);
- POSTERIOR CEREBRAL ARTERY
- POSTERIOR COMMUNICATING ARTERY
- ANTERIOR CEREBRAL ARTERY
- ANTERIOR COMMUNICATING ARTERY
what does the CEREBRAL ARTERIAL CIRCLE (CIRCLE OF WILLIS) supply? and what’s their order within the brain?
leads from the VERTEBRAL ARTERY»_space;> BASILAR ARTERY;
- POSTERIOR CEREBRAL ARTERY
- POSTERIOR COMMUNICATING ARTERY
- ANTERIOR CEREBRAL ARTERY
- ANTERIOR COMMUNICATING ARTERY
supplies OXYGENATED BLOOD, GLUCOSE, and NUTRIENTS to the BRAIN
describe the THORACIC AORTA
- begins at the LOWER BORDER of the FOURTH THORACIC VERTEBRA
- is CONTINUOUS with the AORTIC ARCH
- ends in front of the LOWER BORDER of the 12th THORACIC VERTEBRA
what are the VISCERAL BRANCHES of the THORACIC AORTA and what do they SUPPLY (4)?
- PERICARDIAL BRANCH (supplies the PERICARDIUM)
- BRONCHIAL BRANCH (supplies the LUNGS and BRONCHI)
- ESOPHAGEAL BRANCH (supplies the ESOPHAGUS)
- MEDIASTINAL BRANCH (supplies the POSTERIOR MEDIASTINUM)
what are the PARIETAL BRANCHES of the THORACIC AORTA and what do they SUPPLY (4)?
- POSTERIOR INTERCOSTAL BRANCH (supplies the INTERCOSTAL MUSCLES, SPINAL CORD, VERTEBRAE, PLEURAE, and the SKIN)
- SUBCOSTAL BRANCH
- SUPERIOR PHRENIC (supplies the POSTERIOR and SUPERIOR DIAPHRAGM)
what are the VISCERAL BRANCHES of the ABDOMINAL AORTA (6) AND WHAT DO THEY SUPPY?
- CELIAC TRUNK (has multiple subdivisions that will be addressed later)
- SUPERIOR MESENTERIC (also has multiple subdivisions BUT BROADLY; the SMALL INTESTINE and COLON)
- SUPRARENAL (ADRENAL GLANDS)
- RENAL (KIDNEYS)
- GONADAL (TESTICULAR OR OVARIAN)
- INFERIOR MESENTERIC (also has its subdivisions)
