Question

1. Explain the following in regard to the respiratory system:

Central chemoreceptors

Peripheral chemoreceptors

2. What is the purpose of a cough?

3. What would hemoptysis indicate?

4. Label the following diagram:

6. Describe the gas exchange at the alveolar level.

5. Describe the following respiratory patterns:

Kussmaul Labored Restricted Cheyne-Stokes

6.Or E 3.O 2.5 1.5 NA

Answer 1

1.The peripheral chemoreceptors located in the carotid and aortic bodies and Central chemoreceptors located in the medullary neurones primer really function to regulate respiratary activity this is an important mechanism for maintaining arterial blood tio2, pco2 and pH within approp physiological ranges.

2. Purpose of cough cough is the sudden expansion of air from the stages of the respiratory tract it serve the purpose of clearing our Airways of mucus, bugs and foreign particles.

Hemoptysis is the app of coughing up blood blood stained mucus from the bronchi, larynx, trachea, or lungs. this can occur with lung cancer ,infections such as TB, Bronchitis , pneumonia and certain cardiovascular conditions.

The exchange takes place in the millions of alveoli in the lungs and the capillaries that envelope them inhaled oxygen moves from the alveoli to the blood in the capillaries and carbon dioxide moves from the blood in the capillaries to the air in the alveoli.
