Answer;
Lobules
Explanation;
- In respiratory system the lungs are two spongy, cone shaped organs in the thoracic cavity and are separated from each other by the heart and other structures found in the mediastinum.
- Deep grooves called fissures divide each lung into lobes. Each lobe receives its own secondary bronchus. Each lung lobe is divided into smaller segments that are supplied by a tertiary bronchus.
- The segments, in turn are subdivided into small compartments called lobules, which contains, lymphatic vessel, arteriole, venules and also a branch from terminal bronchiole wrapped in elastic connective tissue.
Each segment of lung tissue is divided into a number of bronchioles wrapped in elastic connective tissue.
Further Explanation:
The lower respiratory tract consists of lungs and tubes that control the air entering into the lungs. The tube that terminates into alveoli includes trachea, bronchi, bronchioles, and alveolar ducts. Lungs are present above the diaphragm and surrounded by the rib cage. They are a very crucial component of the respiratory system. The size of the lung is different; the left lung is less wide than the right one. Lung tissues are sub-divided into various numbers of bronchioles. The inner lining of bronchioles contains cilia and goblet cells that secrete mucus. The cilia help in the up and down movement of the mucus in the conducting airways. These cells are termed as mucociliary escalator and are responsible for preventing the entry of foreign particles and microorganisms into the lungs.
