The respiratory system is responsible for taking in oxygen from the air and releasing carbon dioxide, a waste product of cellular respiration, back into the air.

The trachea is part of the lower respiratory tract, while the nose, pharynx, and larynx are all part of the upper respiratory tract.

The epiglottis is a small flap of tissue that covers the opening of the larynx during swallowing, preventing food and drink from entering the trachea.

The pleura is a thin membrane that lines the chest cavity and covers the lungs, while the bronchi, bronchioles, and alveoli are all part of the lower respiratory tract.

The alveoli are small, thin-walled sacs in the lungs where oxygen and carbon dioxide are exchanged between the air and the bloodstream.

The diaphragm is the primary muscle of respiration, contracting and relaxing to move air in and out of the lungs.

The respiratory system is responsible for regulating blood pH, helping to regulate body temperature, and filtering toxins from the blood, but it does not produce red blood cells.

Ventilation is the process of inhaling and exhaling air, while respiration is the overall process of gas exchange between the air and the bloodstream.

Heart failure is a condition in which the heart is unable to pump blood effectively, while asthma, COPD, and pneumonia are all respiratory disorders.

Atelectasis is the condition in which the lungs are unable to fully expand, while pneumothorax, pleural effusion, and pulmonary embolism are all other respiratory conditions.

Mesothelioma is a type of cancer that affects the pleura, the lining of the chest cavity, while NSCLC, SCLC, and adenocarcinoma are all types of lung cancer.

Bronchitis is the condition in which the airways become inflamed and narrowed, while asthma, emphysema, and pneumonia are all other respiratory conditions.

Dialysis is a type of treatment for kidney failure, while oxygen therapy, nebulized therapy, and chest physiotherapy are all types of respiratory therapy.

Lobectomy is the surgical procedure in which a portion of lung tissue is removed, while pneumonectomy, thoracotomy, and mediastinoscopy are all other surgical procedures related to the respiratory system.

Gloves are personal protective equipment, but they are not specifically designed for respiratory protection, while N95 respirators, surgical masks, and face shields are all types of respiratory protective equipment.
