Blood Vessels & Lymphatics of the Upper Limb

Overview

The vascular and lymphatic systems of the upper limb ensure efficient supply, drainage and immune defence. This section outlines the major arteries, veins and lymphatic channels that support upper limb function.

Key Structures

Topics include the axillary, brachial, radial and ulnar arteries, their venous counterparts, and the superficial and deep venous systems. The organisation of lymphatic drainage and associated nodes is also described.

Clinical Relevance and Learning Focus

A sound knowledge of vascular and lymphatic anatomy is vital for procedures such as venepuncture, grafting and arterial line placement. Learners can relate this anatomy to clinical conditions including embolism, compartment syndrome and lymphoedema.
