Blood Vessels Flashcards

1
Q

Blood vessel

A

-are always defined based on the direction the blood within them is flowing. Away from the heart or towards the heart
- they are never defined based on what type of blood they are carrying, does not matter if its oxygenated or deoxygenated

Q

Directional study of blood

A

-blood vessels should always be studies by their direction of blood flow, arteries away from the heart and veins back to the heart. Arteries branch or diverge, veins converge
