WebbA essential mechanism required for life is pulmonary ventilation. It describes how air enters and exits the lungs. The diaphragm and the intercostal muscles expand and contract to primarily drive this process. The diaphragm and intercostal muscles contract during inhalation, expanding the chest cavity and allowing the lungs to fill with air. highland housing register allocations policyWebbPulmonary arteries originate from pulmonary trunk towards the right ventricle of the human heart and present beneath the aorta. Pulmonary artery consists of two parts. One goes in the right lung and the other towards the left lung. It is the only artery that carries deoxygenated blood from the heart to the lungs.
