Respiratory System

Bradley Pate

What are the structures of the Respiratory System?

The respiratory system is divide into two parts; the upper respiratory tract and the lower respiratory tract. The upper respiratory tract includes the nose, sinuses, epiglottis, pharynx, and the larynx. The lower respiratory tract includes the trachea, bronchi, broncheoli, pulmonary alveoli, and the lungs.

What is the importance of the Respiratory System as it is related to the Immune System?

Of all body systems, only the respiratory system is completely exposed to the external environment. The respiratory system is continuously at risk for infection or damage from external agents. Lymphoid outposts from the immune/lymphatic system help protect the respiratory tract and enhance the defenses that the respiratory system itself erects.

How do you relate the body's use of nutrients to the Respiratory System?

Nutrition can influence the respiratory function. In particular, malnutrition can adversely affect lung function and the adverse effects of such malnutrition include: decreased ventilatory drive, decreased respiratory muscle function, alterations of lung parenchyma and depressed lung defense mechanisms. Therefore, nutrition support should be considered if a patients has a severe chronic pulmonary disease or an acute respiratory disease.
