Like every organ, the lung is composed of segments, although physiologically well-defined boundaries are not always clearly demarcated anatomically.<\/p>\n\n<p class=\"wp-block-paragraph\">Segmental pulmonary arteries, segmental pulmonary veins, and segmental bronchi circulate within these segments, enabling gas exchange in a very confined space. The segmental bronchus and segmental artery run together at the entry point of the lung segment (hilum), while the segmental vein runs separately.<\/p>\n\n<p class=\"wp-block-paragraph\">Several lung segments are anatomically grouped into lung lobes. The right lung consists of three lobes: the upper lobe, the middle lobe, and the lower lobe. The left lung consists of only two lobes: the upper lobe and the lower lobe.<br\/>Histologically, the bronchi continue to divide via the respiratory bronchioles and alveolar bronchioles into the alveolar sacs, where gas exchange occurs.<br\/>Lung tissue serves gas exchange, the regulation of the acid-base balance, and has immunological and endocrine functions.<\/p>\n\n<h5 class=\"wp-block-heading\">Diseases of the lungs (Pulmo):<\/h5>\n\n<ul class=\"wp-block-list\">\n<li>Chronic obstructive pulmonary diseases (COPD, chronic bronchitis, smoker&#8217;s bronchitis); also in the context of chronic sinusitis<\/li>\n\n\n\n<li>Gastroesophageal Reflux Disease<\/li>\n\n\n\n<li>Bronchial asthma<\/li>\n\n\n\n<li>Pulmonary fibrosis<\/li>\n\n\n\n<li>Pulmonary arterial hypertension (high blood pressure in the pulmonary circulation)<\/li>\n\n\n\n<li>Cystic fibrosis (CF, mucoviscidosis)<\/li>\n\n\n\n<li>Pneumonia (pneumonias); also tuberculosis (TB)<\/li>\n\n\n\n<li>Boeck&#8217;s disease (sarcoidosis)<\/li>\n\n\n\n<li>Acute respiratory distress syndrome (ARDS)<\/li>\n\n\n\n<li>Respiratory disorders in the context of other organ diseases (e.g., heart disease, brain disease, etc.)<\/li>\n\n\n\n<li>Lung tumors, benign and malignant<\/li>\n<\/ul>\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n<h3 class=\"wp-block-heading\"><strong>Here you will find several expert interviews related to <\/strong><br\/><strong>lung diseases:<\/strong><\/h3>\n\n<p class=\"wp-block-paragraph\"><strong>#08: Lung cancer diagnosis \u2013 what now?<\/strong><br\/><a href=\"https:\/\/letscast.fm\/sites\/thorax-schweiz-der-podcast-2ee5ab79\/episode\/08-diagnose-lungenkrebs-und-jetzt\" target=\"_blank\" rel=\"noopener\">Thorax-schweiz in conversation with Prof. Dr. med.
