Which of these signs, symptoms and pathological hallmarks is attributed to the correct disease?Question 44Answera.Increased protease and reduced anti-protease activity in alveoli - EMPHYSEMA.b.Excess chloride ion excretion from cells and thin, watery mucus in lungs - CYSTIC FIBROSIS.c.Reduced inflammation in lungs, no alveolar wall damage and high blood O2 saturation - COVID-19.d.Increased respiratory rate and reduced CO2 in blood - CHRONIC BRONCHITIS.e.Metaplasia of epithelial cells in the bronchi - PNEUMONIA.

The correct attributions of signs, symptoms and pathological hallmarks to diseases are as follows:

a. Increased protease and reduced anti-protease activity in alveoli - This is a characteristic of EMPHYSEMA. Proteases are enzymes that break down proteins. In emphysema, there is an imbalance between proteases and anti-proteases (which inhibit proteases), leading to destruction of lung tissue.

b. Excess chloride ion excretion from cells and thin, watery mucus in lungs - This is a characteristic of CYSTIC FIBROSIS. In this genetic disorder, a defect in the CFTR gene leads to abnormal transport of chloride and other ions across cell membranes. This results in thick, sticky mucus in the lungs and other organs.

c. Reduced inflammation in lungs, no alveolar wall damage and high blood O2 saturation - This is NOT a characteristic of COVID-19. In fact, COVID-19 often causes severe inflammation in the lungs, damage to the alveolar walls, and low blood O2 saturation.

d. Increased respiratory rate and reduced CO2 in blood - This is NOT a characteristic of CHRONIC BRONCHITIS. In chronic bronchitis, there is usually a decrease in respiratory rate and an increase in CO2 in the blood due to impaired gas exchange.

e. Metaplasia of epithelial cells in the bronchi - This is NOT a characteristic of PNEUMONIA. Metaplasia in the bronchi is more commonly associated with conditions like chronic bronchitis or lung cancer. Pneumonia is typically characterized by inflammation and infection of the alveoli in the lungs.

The correct attributions of signs, symptoms and pathological hallmarks to diseases are as follows:

a. Increased protease and reduced anti-protease activity in alveoli - This is a characteristic of EMPHYSEMA. Proteases are enzymes that break down proteins. In emphysema, there is an imbalance between proteases and anti-proteases (which inhibit proteases), leading to destruction of lung tissue.

b. Excess chloride ion excretion from cells and thin, watery mucus in lungs - This is a characteristic of CYSTIC FIBROSIS. This genetic disorder affects the cells that produce mucus, sweat and digestive juices, causing them to become thick and sticky.

c. Reduced inflammation in lungs, no alveolar wall damage and high blood O2 saturation - This is NOT a characteristic of COVID-19. In fact, COVID-19 often causes significant inflammation in the lungs, can damage the alveolar walls, and can lead to low blood O2 saturation.

d. Increased respiratory rate and reduced CO2 in blood - This is NOT a characteristic of CHRONIC BRONCHITIS. Chronic bronchitis typically results in a slower respiratory rate and higher levels of CO2 in the blood due to impaired gas exchange.

e. Metaplasia of epithelial cells in the bronchi - This is NOT a characteristic of PNEUMONIA. Pneumonia is an infection that inflames the air sacs in one or both lungs, which may fill with fluid or pus, but it does not typically cause metaplasia (abnormal change in the nature of a tissue) in the bronchi.
