1. alveoli

1. diaphragm

ii. directions describe each respiratory problem in the space provided.

1. asthma:

1. tuberculosis:

1. emphysema:

cardiovascular, respiratory, and digestive systems

Explanation:

1. Asthma is a chronic respiratory condition where the airways become inflamed, swollen, and produce extra mucus. This leads to difficulty in breathing, coughing, wheezing, and shortness of breath. Triggers can include allergens (like pollen, dust mites), exercise, cold air, and respiratory infections.
2. Tuberculosis (TB) is an infectious disease caused by the bacterium Mycobacterium tuberculosis. It mainly affects the lungs. Symptoms include a persistent cough (often with blood), chest pain, weight loss, fatigue, fever, and night sweats. It spreads through the air when an infected person coughs or sneezes.
3. Emphysema is a type of chronic obstructive pulmonary disease (COPD). In emphysema, the alveoli (air - sacs in the lungs) are damaged. This reduces the surface area for gas exchange (oxygen intake and carbon dioxide release). Symptoms include shortness of breath (especially during physical activity), a chronic cough, and wheezing. Smoking is a major risk factor.

Answer:

1. Asthma: A chronic respiratory condition with airway inflammation, swelling, mucus over - production, causing breathing difficulties, cough, wheeze, and shortness of breath. Triggers: allergens, exercise, etc.
2. Tuberculosis: Infectious disease (Mycobacterium tuberculosis). Mainly lung - affected. Symptoms: persistent cough (may have blood), chest pain, weight loss, fatigue, fever, night sweats. Spreads via air.
3. Emphysema: Type of COPD. Damaged alveoli reduce gas exchange. Symptoms: shortness of breath (worse with activity), chronic cough, wheeze. Smoking is a major risk.
