Study Notes
Respiratory System
- Respiratory system is responsible for breathing, supplying oxygen, and removing carbon dioxide.
- Composed of various structures including airways, lungs, thorax, and diaphragm.
Respiratory Processes
- Ventilation: Movement of air in and out of the lungs. This includes inspiration (inhaling) and expiration (exhaling).
- Diffusion: Exchange of gases (oxygen and carbon dioxide) between alveoli and blood.
- Perfusion: Blood flow to the lungs for gas exchange.
Respiratory Structures
- Airways (nose, pharynx, larynx, trachea, bronchi, and bronchioles): Channels for air flow.
- Lungs: Contain alveoli for gas exchange.
- Thorax: Protects the lungs and heart. The diaphragm is the main muscle for respiration.
- Respiratory Center: Located in the brainstem (medulla oblongata and pons). Regulates breathing.
Dyspnea
- Difficulty in breathing (shortness of breath).
- Can be acute (sudden) or chronic (ongoing).
- Characterized as mild, moderate, or severe, based on intensity.
Thorax and Diaphragm
- The thorax (chest cavity) protects vital organs, and contains the lungs and heart.
- The diaphragm is a key muscle for inhalation and exhalation.
Pleura
- Two-layered membrane surrounding the lungs.
- Reduces friction during breathing.
Lungs
- Key organ in the respiratory system.
- Contains alveoli, where gas exchange occurs.
- Right lung has three lobes; left lung has two.
- Alveoli is the site for oxygen exchange with the blood stream.
Respiration
- It's the process of gaseous exchange between individual and an environment.
- The main process is breathing in oxygen and breath out carbon dioxide.
Respiratory Tests and Procedures
- Bronchoscopy: Direct inspection of larynx, trachea, and bronchi.
- Bronchography: Instilling a radiopaque medium into the bronchial tree for Xray visualization.
- Chest X-Ray: Used to visualize the lungs and chest structure.
- Pulmonary Function Studies: Assess lung function (e.g., spirometry).
- Lung Scan: Assess blood flow in the lungs.
- Arterial Blood Gases (ABG): Assess blood's oxygen and carbon dioxide levels.
- Thoracentesis: Removing fluid or air from the pleural space.
- Lung Biopsy: Removing tissue from the lungs for examination.
Important Information
- Diseases like pneumonia, tuberculosis, and asthma can affect the respiratory system.
- Smoking and pollution are associated with respiratory problems.
- Symptoms of respiratory problems include coughing, shortness of breath, and wheezing.
