Study Notes
Primary and Secondary Functions of the Respiratory System
- Primary function: Gas exchange (oxygen intake and carbon dioxide elimination)
- Secondary functions include:
- Regulation of acid-base balance
- Phonation (voice production)
Respiration Types
- External respiration: Exchange of gases between air and blood in the lungs
- Internal respiration: Exchange of gases between blood and tissues
Respiratory Structures
- Upper respiratory tract includes:
- Nasal passages
- Pharynx
- Larynx
- The nasal passages are lined with ciliated epithelium for mucus movement and filtration.
Nasal Passages and Turbinates
- Nasal passages: Warm and humidify incoming air, trapping particles in mucus.
- Turbinates are thin, scroll-like bones that divide each nasal passage, increasing surface area for air processing.
- Soft palate separates the nasal passages from the mouth.
Pharynx Functions
- Primary function: Conduct air to the larynx and food to the esophagus.
- Divided into nasopharynx (dorsal) and oropharynx (ventral).
- Caudal end opens into the esophagus (dorsally) and larynx (ventrally).
Larynx and Vocalization
- Larynx functions include voice production and protection of the airway during swallowing.
- The epiglottis covers the larynx during swallowing.
- Arytenoid cartilages control vocal cord tension.
Trachea and Bronchial Tree
- Trachea: Conducts air to the lungs, lined with ciliated epithelium and supported by C-shaped hyaline cartilage rings.
- Bronchial tree subdivides into bronchi, smaller bronchi, and bronchioles, eventually leading to alveolar sacs.
Alveoli
- Alveoli are tiny, thin-walled sacs where gas exchange occurs, surrounded by capillaries.
- Alveolar ducts end in clusters of alveoli, maximizing surface area for efficient gas exchange.
Regulation of Bronchi and Bronchioles
- Smooth muscle fibers in the bronchial tree are controlled by autonomic nervous system reflexes.
- Bronchoconstriction reduces airway size, aiding in the protection against irritants.
Pleural Cavity and Fluid
- Pleural fluid reduces friction between lung surfaces during respiration.
- The area between the lungs is known as the mediastinum.
Lung Lobes and Structures
- Lung lobes are arranged differently across species, often with a standard pattern.
- The diaphragm forms the caudal boundary of the thorax, assisting with inspiration.
Pulmonary Circulation and Functions
- Pulmonary circulation oxygenates blood in the lungs and returns it to the heart.
- The respiratory system works in conjunction with the cardiovascular system to maintain homeostasis.
