Respiratory System 

   Why do we need the respiratory system? We use the respiratory system to breathe and it allows gas exchange in the lungs.

   What are the major components of the respiratory system? One major component is an air conducting component. It consists of:

• Nasal cavities
• Pharynx
• Larynx
• Trachea
• Extrapulmonary bronchi
• Intrapulmonary bronchi
• Terminal bronchioles.

    Extrapulmonary bronchi are the left and right bronchi that branches off of the trachea and enters the lungs. Intrapulmonary are bronchi the form within the lungs. The air conducting component also filters, moistens, and warms air before it enters the lungs.

    The second major component of the respiratory system is a respiratory component. It consists of: 

• Respiratory bronchioles
• Alveolar ducts
• Alveolar sacs
• Alveoli

  What are the organs involved in the respiratory system?

   What is the structure and function of the alveoli?  There are 150 million alveoli in your lungs that help you breathe. Alveoli are tiny air sacs in your lungs. Their function is to perform the gas exchange in your lungs.

  How does the respiratory system work with other systems? The respiratory system works with every system, but two of the more important systems that it works with is the nervous and skeletal system. It works with the skeletal system because the bones in the skeletal system protect organs such as the lungs, of the respiratory system.

   The other system it works with is the nervous system. The respiratory system relies on the nervous system to do normal bodily activities such as, breathing, without having to constantly think about doing it.
