What are the 2 protective measures that aid the respiratory system?

The respiratory system contains several protective mechanisms to avoid problems or tissue damage. In the nasal cavity, hairs and mucus trap small particles, viruses, bacteria, dust, and dirt to prevent their entry.

What are some protective mechanisms of the respiratory system?

Protection mechanisms of the respiratory system. 1 – mechanical filtration, 2 – electrostatic filtration, 3 – air-conditioning, 4 – humidification, 5 – reflex apnoea, 6 – laryngeal constriction, 7 – broncho- constriction. charged particles dispersed in the air.

What protect the lungs and heart?

The ribs are connected to the sternum with a strong, somewhat flexible material called cartilage. The rib cage help protects the organs in the chest, such as the heart and lungs, from damage.

Which equipment is used for protection of lungs?

Compressed airline breathing apparatus (CABA) with half mask. Compressed airline breathing apparatus (CABA) or powered fresh air hose breathing apparatus (FAHBA) with full face-mask. Compressed airline breathing apparatus (CABA) or powered fresh air hose breathing apparatus (FAHBA) with hood, helmet or visor.

What features of the respiratory system protect it from infection?

Cilia propel a liquid layer of mucus that covers the airways. The mucus layer traps pathogens (potentially infectious microorganisms) and other particles, preventing them from reaching the lungs.

When recovering from a respiratory illness like COVID-19, it’s important not to rush recovery.

What are the five main mechanisms of defense for the respiratory system?

Knowledge of these mechanisms is key when modulating immunity to increase defence mechanisms or decrease allergic phenomena.

  • Alveolar macrophages.
  • dendritic cells.
  • lung defences.
  • lung immunity.
  • lymphocytes.
  • neutrophils.

What is the defense mechanism that helps protect the lung from inhaled particles quizlet?

Respiratory defense mechanisms are efficient in protecting the lungs from inhaled particles, microorganisms, and toxic gases. Below the larynx, the movement of mucus is accomplished by the mucociliary clearance system, commonly referred to as the mucociliary escalator. Filtration of particles occurs in the nasopharynx.

How does cilia protect the respiratory system?

The bronchus in the lungs are lined with hair-like projections called cilia that move microbes and debris up and out of the airways. Scattered throughout the cilia are goblet cells that secrete mucus which helps protect the lining of the bronchus and trap microorganisms.
