The arteries are part of the bridging system that connect the parts of the body that enable the “whole” to function.
Specifically they are the conduits that deliver blood to the organs from the heart.
There are two separate arterial systems in the body
The systemic arterial system
The pulmonary arterial system

Note that the lobar pulmonary arteries have the same irregular dichotomous branching pattern as the lobar bronchi and give 3 major branches to the right lung (RUL, RML and RLL arteries) and two to the left (LUL and LLL pulmonary arteries). As you will see and learn later, even the position and direction of the main pulmonary arteries in relation to the main stem bronchi are asymmetrical.

The Arterial Circulation |
| The systemic arteries (shown in red) take their origin from the heart and deliver blood to structures from the head to the toe ensuring so that all the systemic organs and their cells receive adequate oxygenated blood. The pulmonary circulation carries the deoxygenated blood to the lungs
