The <strong>pulmonary trunk<\/strong> then bifurcates (splits) into the <strong>right and left pulmonary arteries<\/strong>, which transport blood to the corresponding lungs.<\/p>\n\n\n\n<p>Within each lung, these pulmonary arteries branch further into <strong>lobar arteries<\/strong>\u2014named according to the lobes of the lung they supply:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>The <strong>right lung<\/strong> has three lobes (superior, middle, and inferior), and therefore it has:\n<ul class=\"wp-block-list\">\n<li><strong>Superior lobar artery<\/strong><\/li>\n\n\n\n<li><strong>Middle lobar artery<\/strong><\/li>\n\n\n\n<li><strong>Inferior lobar artery<\/strong><\/li>\n<\/ul>\n<\/li>\n\n\n\n<li>The <strong>left lung<\/strong> has two lobes (superior and inferior), so it lacks a middle lobar artery but includes:\n<ul class=\"wp-block-list\">\n<li><strong>Superior lobar artery<\/strong><\/li>\n\n\n\n<li><strong>Inferior lobar artery<\/strong><\/li>\n<\/ul>\n<\/li>\n<\/ul>\n\n\n\n<p>Each lobar artery continues branching into segmental arteries that further supply the lung tissue for gas exchange.<\/p>\n\n\n\n<p>After oxygenation in the alveoli, oxygen-rich blood returns to the <strong>left atrium<\/strong> via the <strong>pulmonary veins<\/strong>. From there, it passes into the <strong>left ventricle<\/strong>, which is not a direct part of pulmonary circulation but rather systemic circulation.
