Midterm | L8: Circulatory System Radiologic Correlation Flashcards
largest artery main artery that carries blood away from heart to the rest of the body.
Aorta
4 principal divisions of the aorta:
- Ascending Ao
- Ao arch
- Thoracic Ao
- Abdominal Ao (descending)
CIRCULATORY ROUTES
- Systemic circulation
- Pulmonary circulation
Moves blood between the heart and the rest of the body.
Systemic circulation
Moves blood between the heart and the alveoli.
Pulmonary circulation

The only artery that carries deoxygenated blood
PULMONARY ARTERY
The only vein that carries oxygenated blood
PULMONARY VEIN
Three major arteries branch from the superior aspect of the arch of the aorta:
- Brachiocephalic trunk
- Left common carotid
- Left subclavian
innominate artery
BRACHIOCEPHALIC ARTERY
1st and largest branch of the aortic arch
BRACHIOCEPHALIC ARTERY
BRACHIOCEPHALIC ARTERY bifurcates into the (1) and the (2)
- right common carotid
- right subclavian artery
Where INTERNAL AND EXTERNAL JUGULAR VEIN drain blood from
Head and neck area
Where AXILLARY VEIN drains blood from
Arm and axilla
Where AZYGOS VEIN drain blood from
Thoracic and abdominal walls
FOUR CHAMBERS OF HEART
(2) ATRIA: receiving chambers.
(2) VENTRICLE pumping chamber
Wrinkled pouchlike structure that slightly increases the capacity of an atrium
AURICLE
Marks external boundary b/n two chambers of the heart
SULCUS/ SULCI
Between right left ventricles
ANTERIOR INTERVENTRICULAR SULCUS
R ATRIUM receives blood from three veins
SVC
IVC
Coronary Sinus
Prevents the backflow of blood from the RV to the RA
Tricuspid valve/ Right atrioventricular valve
R VENTRICLE:
Deoxygenated blood to (1) to (2) to the (3) to receive (4)
- Pulmonary valve (Semilunar Valve)
- pulmonary arteries
- lungs
- 02
Where blood is received from the lungs by the pulmonary veins.
LA
Mitral valve other terms
Bicuspid valve
L. atrioventricular valve.
Thickest heart chamber
LV
LV pumps (1) blood into the aorta through (2)
- oxygen rich blood
- Aortic valve
Help ensure the one- way flow of blood
Valves
The brain receives blood from 2 sources
CAROTID ARTERIES
VERTEBRAL ARTERIES
INTERNAL CAROTID ARTERIES branch to form (1) AND (2).
- MIDDLE CEREBRAL
- ANTERIOR CEREBRAL ARTERY
RIGHT and LEFT VERTEBRAL ARTERIES come together to form the —
BASILAR ARTERY
— bifurcate from the basilar artery.
POSTERIOR CEREBRAL ARTERY
ANTERIOR
COMMUNICATING
ARTERY runs (1) between the (2).
- horizontally
- anterior cerebral arteries
Connection of blood arteries
Anastomosis
A circulatory anastomosis that supplies blood to the brain and surrounding structures
