Near origin of ascending aorta
What blood vessels branch off the aortic arch?
Right to left:
- Brachiocephalic trunk
- Left common carotid artery
- Left subclavian artery
What blood vessels branch off the brachiocephalic trunk?
Right common carotid artery and right subclavian artery
What does the descending aorta turn into?
The thoracic aorta then the abdominal aorta
What is the structural and functional relationship of capillaries to other blood vessels?
Capillaries are smaller than arteries and veins and will exchange substances to diffuse into surrounding tissue
What blood vessel do you press down on to take a pulse?
Right and left common carotid artery
What blood vessels branch off the Ascending Aorta?
The right and left coronary arteries
Specific arteries carry deoxygenated blood
In adult: pulmonary arteries
In fetus: umbilical arteries
Specific veins that carry oxygenated blood?
In adults: pulmonary veins
In fetus: umbilical veins
Aortic hiatus
