In the right lung, there are three lobes, the superior, middle, and inferior. It is divided into three lobes by two interlobular fissures, transverse fissure and oblique fissure (Taylor, n.d.). The superior and middle lobe are separated by a transverse fissure and the middle and inferior lobe are separated by an oblique fissure (“Structure of the Lungs”, n.d.). The left lung and right lung are not the same though. As you see, the right lung has only three lobes, as the left lung has two. They are different in size as the left lung is smaller than the right. The reasoning for this is because your hearts sets in between the lungs so the heart uses some of the space that your left lung is (Taylor, n.d.). The function of the lungs is pulmonary ventilation, or breathing. Air is inhaled through your nostrils which pass through your trachea and enters the bronchi. Bronchi are two tubes that carry air to the lungs. Bronchioles are smaller branches of bronchi that split off (“Structure of the Lungs”, n.d.). Bronchioles divide into even smaller structures to form respiratory bronchioles which lead to the alveolar ducts. Then there are air sacs called alveoli. They are the basic functional units of lungs and have simple squamous epithelial cells. Alveoli cover about 60-70m. Oxygen is exchanged for carbon dioxide from the bloodstream by microscopic structures of the lungs called alveoli. Pleura protects the lungs with a…

C. Which structures found in the terminal bronchioles and alveoli normally would protect cari’s lungs from infectious pathogens and particulate matter? Normally goblet cells secrete mucous to trap particles while cilia works by moving mucous towards the pharynx for removal. Cigarette smoke damages and destroys cilia, and causes goblet cells to produce increased amounts of mucous. The damaged cilia combined with increased mucous obstructs airflow in and out of the lungs.…
