The pulmonary system is the group of organs consisting of
the trachea, bronchi, and lungs. This system facilitates the gas
exchange essential for life, allowing the absorption of oxygen
and the elimination of carbon dioxide from the body.
The respiratory epitheliumlines the airways,such as the tracheaand bronchi. It produces mucusand contains ciliathat help protect, clean, and humidify the air entering the respiratory system.
The respiratory mucous membranelines the tracheaand bronchi, producing mucusand using ciliato clean, protect, and humidify the air entering the respiratory system.
The respiratory system allows the body to obtain oxygen and remove carbon dioxide. Moreover, its organs work together to keep the body balanced. Therefore, understanding how breathing works helps protect respiratory health.
The respiratory systemincludes organs such as the nose, pharynx, larynx, trachea, bronchi, and lungs. These structures allow the exchange of oxygen and carbon dioxideduring breathing.
The rib cage is a skeletal structure made of ribs,
sternum, and thoracic vertebrae. It protects the
heart and lungs while supporting breathing
movements.
The structure of the bronchishows how these airways carry air from the tracheainto the lungs, branching into secondary bronchiand bronchiolesto distribute air throughout the respiratory system.
The structure of the pulmonary alveolusconsists of tiny air sacs surrounded by blood capillaries. These structures allow the exchange of oxygen and carbon dioxide, a vital process for breathing and body function.
Thoracic cavity layers include skin, subcutaneous tissue,
intercostal muscles, ribs, and costal cartilage. Together, they
protect the heart and lungs while supporting breathing
movements.
Thoracic cavity muscles assist breathing by moving the
ribs and diaphragm. They support lung expansion and
protect vital organs such as the heart, lungs, trachea,
and major blood vessels.
Thoracic wall layers include skin, subcutaneous tissue,
intercostal muscles, and ribs. These structures protect
vital organs and allow chest movements required for
breathing.
The three bronchial states show a healthy bronchus, one with
bronchitis, and another with asthma. Each one presents inflammation,
mucus, or constriction, affecting airflow and constriction in the airways.
