Section 3 The Arteries
The Cardiovascular Circuits 1) The systemic (greater) circulation The direction of blood flow : arterial blood
the left ventricle → the aorta → branches of
venous blood
arteries → the capillaries of whole body →
tributaries of veins → the superior and inferior venae cavae → the right atrium
2) The pulmonary (lesser) circulation The flow of blood of direction: venous blood
the right ventricle → the pulmonary trunk → the branches of the pulmonary arteries → the arterial blood
pulmonary capillaries → the pulmonary veins → the left atrium
1. The arterial anastomoses
arterial arch
vein artery the arterial network the arteriovenous anastomoses
the collateral circulation Trunk of artery Collateral vessels
