Pulmonary Circulation:The part of the circulatory system responsible for carrying deoxygenated blood from the right ventricle of the heart to the lungs and returning oxygenated blood back to the left atrium of the heart.
Systemic Circulation: The portion of cardiovascular circulation which carries oxygenated blood away from the heart through arteries, delivers it to most body tissues, and returns deoxygenated blood back to the heart through veins.
Bronchial Arteries: These arteries supply oxygenated blood to the tissue of the bronchi, supporting their function and structure within the respiratory system
