Study Notes
Primary Tissues in Respiratory System
- Tissues are composed of cells and extracellular matrix (ECM).
- Four primary types of tissues: epithelial, connective, muscle, and nerve.
Respiratory Airway Functions and Structure
- Study focuses on the bronchus as a model for general airway structure.
- Airways are divided into two structural groups: extrapulmonary and intrapulmonary.
- Extrapulmonary includes nasal cavity, pharynx, larynx, trachea, and bronchi.
- Intrapulmonary includes tertiary bronchi, bronchioles, respiratory bronchioles, alveolar ducts, and alveoli.
Conducting and Respiratory Portions
- Conducting airways: nasal cavity, upper airways, trachea, bronchi.
- Respiratory airways: respiratory bronchioles, alveolar ducts, and alveolar sacs.
- Each component features unique structural attributes that support specific respiratory functions.
Blood-Air Barrier
- The blood-air barrier is formed by cellular and structural elements that facilitate gas exchange.
- This barrier consists of alveolar epithelial cells, capillary endothelial cells, and the underlying basement membrane.
Histological Differences
- Active and inactive breast tissues exhibit distinct histological characteristics.
- Study involves identifying and annotating differences in cellular structure and arrangements.
Visual Aids
- Annotate sketches and photomicrographs to support understanding of bone histology.
Structural Components to Identify
- Trachea
- Bronchi
- Terminal bronchioles
- Respiratory bronchioles
- Alveolar ducts
- Alveoli
Basic Building Plan of Airways
- Airways structure includes a variety of epithelial cell types, glands, cartilage, smooth muscle, and connective tissue fibers.
- Understanding the distribution of these components is crucial for identifying respiratory tract structures.
Key Facts
- The respiratory system has distinct functional groups (conducting vs. respiratory).
- Knowledge of histology is essential for understanding respiratory function and pathology.
