What are the two main routes for blood vessels?
Introduction
Systemic - supply tissue of body
Pulmonary - Blood to and from lungs
What are the 3 groupings we wll learn CR
Introduction
Arteries - away from heart
Veins - towards heart
Specialized Circulatory routes
a. hepatic portal system
b. Pulmonary circulation
c. Fetal circulation
What should we know about each vessel?
Introduction
Name
Direction
Where it travels
Vessels they arise from
What vessels they form
What tissue they supply
What are the first branches off the aorta?
Branches of the ascending aorta
Left and Right coronary arteries
What does the Right Coronary Artery branch into? What it supply?
Branches of the Ascending Aorta
Marginal Artery (Right Atrium)
Posterior Interventricular Artery (Right and Left Ventricles)
Supplies aright atrium
What does the Left Coronary Artery Branch into?
Branches of the Ascending Aorta
Anterior Interventricular Artery (Left and Right ventricles)
Circumflex Artery (Left atrium and left ventricle)
What are the three main branches of the Arch of the Aorta?
Branches of the Arch of the Aorta
- Brachiocephalic Trunk
- Left Common Carotid Artery
- Left Subclavian Artery
What is the order of the right side of head/neck?
Starting at Arch of Aorta
Arteries of the head and neck
Arch of Aorta - Brachiocephalic Trunk - Right Common Carotid
What is the order of the left side of the neck?
Starting at Arch of Aorta
Arteries of the head and neck
Arch of the aorta - Left common carotid
Where do both common carotids lead to?
Arteries of the Head and Neck
Internal carotid artery
External carotid artery
External carotid feeds what?
Arteries of the head and neck
Superficial external neck, face and head structures
What does the internal carotid feed?
Arteries of the Brain
Through the carotid canal, feeds brain and eyes via circle of willis
What does the Vertebral Artery feed?
Arteries of the Brain
Through foramen magnum, feeds circle of willis, via Basilar artery
What is the circle of willis
Arteries of the Brain
Arteries that feed the brain
Mainly from Internal carotid artery
What is the vertebral artery?
Arteries of the brain
Branch from subclavian,
travel through transverse foramen, fuse to basilar artery, feed circle of willis
What is the order of the right side?
Starting from Arch of the Aorta
Upper Extremity
Arch of the aorta - Brachiocephalic trunk - Right subclavian
What is the order of the left side?
Starting from Arch of Aorta
Upper Extremity
Arch of the aorta - Left subclavian
What branches off the Subclavian artery
Upper Extremity
- Internal thoracic/mammary artery
- Vertebral artery
