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
