Bronchial artery
Bronchial artery
The Bronchial artery (pronunciation: /ˈbrɒŋkiəl ˈɑːrtəri/) is a part of the human circulatory system that supplies oxygenated blood to the bronchi and bronchioles of the lungs.
Etymology
The term "Bronchial artery" is derived from the Greek words "bronkhos" meaning windpipe and "arteria" meaning windpipe.
Anatomy
The bronchial arteries originate from the thoracic aorta and sometimes from other nearby arteries. There are typically two bronchial arteries on the left and one on the right, but this can vary. They follow the bronchial tree through its branching and supply the bronchi and connective tissue of the lungs.
Function
The primary function of the bronchial arteries is to provide oxygenated blood to the lungs. This is in contrast to the pulmonary arteries, which carry deoxygenated blood from the heart to the lungs for oxygenation.
