What is the respiratory tract first line of defense?
Because normal breathing is done through the nose, most airborne particles are filtered through the nose. Thus, the nasal mucosa is the front line of defense against airborne particles.
What are three ways the nasal cavity helps to protect your respiratory system?

Which of the following membrane covers the lungs?
There are two layers The outer pleura (the mural pleura) attaches to the chest wall, while the inner pleura (the visceral pleura) covers the lungs and adjacent structures via blood vessels, bronchi, and nerves.
Which structure helps in protecting heart against any physical injury?
∙ So, the correct answer is thorax.
What is air sacs in lungs?
Listen to the pronunciation. (al-VEE-oh-ly) A small air sac (a small branch of the trachea of the lungs) at the end of a bronchus. Alveoli are places where the lungs and blood exchange oxygen and carbon dioxide in the process of breathing in and out.
Which of the following structures protects the lungs from rubbing against the chest wall?
Pleura. The outer or wall pleura covers the inner part of the rib cage and diaphragm, while the inner visceral or lung layer covers the lungs.
Can you live without your ribs?
One can lead a fairly normal life without one lung, a kidney, spleen, appendix, gallbladder, adenoids, tonsils, some lymph nodes, a fibula in each leg, and six ribs.
Which organ is protected by last two ribs?

What is pulmonary defense?
Overview. Lung defense involves a variety of mechanisms necessary to remove inhaled particles and organisms. The various innate immune processes that occur in the central or more distant airways are outlined.
How does the immune system protect the respiratory system?
The removal of this debris is an important part of the immune system that protects the respiratory system from infection. The epithelial layer of the lungs also contains specialized white blood cells called macrophages, which are able to swallow and destroy foreign particles in the lungs .
Is coughing a respiratory defense mechanism?
Coughing, along with mucociliary clearance, bronchoconstriction and phagocytosis, is a natural defense mechanism that effectively protects the airways from inhalation of foreign substances and clears excessive bronchial secretions (1).

How does the body defend itself against infection?
In general, your body fights disease by keeping foreign substances away from your body. The primary defense against pathogens is the physical barrier, such as the skin. It also produces chemicals that destroy pathogens, such as lysozyme. This is found in parts of the body without skin, such as tears and mucous membranes.
What is the body’s first defense against infection?
The innate immune system is the front line of defense against bacteria entering the body. It is sometimes called the “nonspecific” immune system because it reacts the same way to all bacteria and foreign substances.
Can the lungs repair themselves?
The lungs are self-cleaning. This means that when you stop smoking, your lungs will gradually heal and regenerate themselves. However, there are certain lifestyle behaviors that can be practiced to speed up the rate of lung healing.
