22
Q

What carries blood to the heart and away from the organs and tissues?

23
Q

What is the vasa vasorum?

Study These Flashcards
A

The vessels of the vessels

24
Q
  • Provides the functional blood supply to all
    body tissue.
  • It carries oxygen and nutrients to the cells.
  • Picks up carbon dioxide and waste products.
  • Systemic circulation carries oxygenated blood
    from the left ventricle, through the arteries, to
    the capillaries in the tissues of the body.
Study These Flashcards
A

Systemic Circulation

25
- Connection between vessels. - Union of two vessels going to the same body part
Anastomoses
26
What is collateral circulation?
Alternate or backup blood vessels Connection between vessels. Union of two vessels going to the same body part.
27
When does collateral circulation happen?
Take over when another artery or vein become blocked or damaged
28
The ______ begins at the left ventricle of the heart. Extends upward into the chest to form an arch. It then continues downward into the chest and the abdomen cavities. Ends at the iliac arteries just above the pelvis
Aorta
29
What are the branches of the aortic arch?
Brachiocephalic artery Left common carotid artery Left Subclavian artery
30
What are the branches of the Brachiocephalic artery?

32
What goes after the Right radial artery and right ulnar artery?
Right superficial palmar arch‐right digits
33
What branch is after the Right Common Carotid Artery?
Right external carotid artery
34
What are the branches of the Right external carotid artery?
