Summary
The blood supply of the upper limb originates from the aorta and its branches, particularly the common carotid artery and subclavian artery .
Venous drainage of the upper limb is managed through both deep and superficial veins, culminating in the superior vena cava for return to the heart. Understanding these vascular systems is crucial for clinical evaluation and surgical interventions related to the upper limb.
