1. State and give one function each of 5 organ of the respiratory system in human
2. Mention five diseases of the respiratory system
1. The respiratory system in humans consists of several organs, including:
- Nasal Cavity: Functions to filter, warm, and moisten the air we breathe before it reaches the lungs.
- Pharynx: Provides a pathway for air to move from the nasal cavity to the larynx.
- Larynx: Helps produce sound and acts as a route for air to enter the trachea.
- Trachea: Allows air to pass from the larynx to the bronchial tubes.
- Lungs: The primary organs of respiration, where oxygen is taken in, and carbon dioxide is expelled.
2. Some common diseases of the respiratory system include:
- Asthma: A chronic condition characterized by difficulty breathing and narrowing of the airways.
- Chronic obstructive pulmonary disease (COPD): A progressive lung disease that causes breathing difficulties and airflow limitation.
- Pneumonia: An infection in one or both lungs that causes inflammation, cough, and difficulty breathing.
- Tuberculosis (TB): An airborne bacterial infection that primarily affects the lungs, causing chest pain, cough, and fatigue.
- Lung cancer: A malignant tumor that originates in the lungs and impairs the organ's function.
