BRONCHIAL ARTERIES Meaning and
Definition
-
Bronchial arteries are a set of small blood vessels that supply oxygenated blood to the bronchial tree, which includes the bronchi, bronchioles, and alveoli in the lungs. These arteries arise from the thoracic aorta and are responsible for nourishing the lung tissue and supporting its proper functioning.
The bronchial arteries exhibit a high degree of variability in their origin, course, and distribution. In most cases, there are one or two bronchial arteries that arise directly from the thoracic aorta, just above the diaphragm. Occasionally, additional branches may originate from intercostal arteries or other arteries in nearby structures.
Once the bronchial arteries are formed, they typically travel along the bronchi and bronchioles, supplying oxygen-rich blood to the lung tissue. These arteries may also provide nutritional support to the supporting structures of the lung, such as the bronchial glands, connective tissue, and visceral pleura.
The blood supplied by the bronchial arteries is distinct from the oxygenated blood flowing through the pulmonary arteries, which carry deoxygenated blood from the right ventricle of the heart to the lungs for oxygenation. The bronchial arteries ensure that the lung tissues receive the necessary oxygen and nutrients for metabolic processes, independent of the oxygen supply from the pulmonary circulation.
Disorders or diseases affecting the bronchial arteries can lead to compromised blood flow, resulting in lung tissue hypoxia and potential complications. Understanding the anatomy and function of bronchial arteries is important in clinical fields, such as cardiology, pulmonology, and thoracic surgery, as it assists in diagnosing and treating conditions related to the blood supply of the bronchial tree.

Etymology of BRONCHIAL ARTERIES
The word "bronchial" comes from the Greek word "bronkhos", which means "windpipe" or "trachea". The term "arteries" is derived from the Latin word "arteria", meaning "air passage or windpipe", which was originally used to refer to the blood vessels thought to carry air rather than blood. Hence, the term "bronchial arteries" refers to the arteries supplying blood to the bronchial tubes or air passages in the lungs.
