What are the 5 main functions of the respiratory system?

Top 5 Functions of the Respiratory System: A Look Inside Key Respiratory Activities Inhalation and Exhalation Are Pulmonary Ventilation—That’s Breathing. External Respiration Exchanges Gases Between the Lungs and the Bloodstream. Internal Respiration Exchanges Gases Between the Bloodstream and Body Tissues.

What are the 6 functions of the respiratory system?

The functions of the respiratory system include gas exchange, acid-base balance, phonation, pulmonary defense and metabolism, and the handling of bioactive materials.

How many parts does the respiratory system have?

There are 3 major parts of the respiratory system: the airway, the lungs, and the muscles of respiration. The airway, which includes the nose, mouth, pharynx, larynx, trachea, bronchi, and bronchioles, carries air between the lungs and the body’s exterior.

What are the 5 diseases of the respiratory system?

The Top 8 Respiratory Illnesses and Diseases Asthma. Chronic Obstructive Pulmonary Disease ( COPD ) Chronic Bronchitis. Emphysema. Lung Cancer. Cystic Fibrosis / Bronchiectasis. Pneumonia. Pleural Effusion.

What is the structure of the lungs?

About the lungs The right lung has three lobes and the left lung has two lobes. The lungs are covered by a lining called the pleura, which has two layers. The inner layer covers the lungs. The outer layer lines the ribcage and a sheet of muscle called the diaphragm.

What is the main function of lungs in a human body?

The trachea (windpipe) conducts inhaled air into the lungs through its tubular branches, called bronchi. The bronchi then divide into smaller and smaller branches ( bronchioles ), finally becoming microscopic.
