Study Notes
Respiratory System Overview
- The respiratory system is responsible for breathing and gas exchange, providing oxygen to the body and removing carbon dioxide.
- It's composed of various structures.
Respiratory Structures - Upper Airways
- Nose (nasal cavity, nasal conchae, nasal vestibule): Warms, filters, and humidifies incoming air; opening of the nose is called the vestibule
- Vibrissae: Hair that lines the vestibule to filter out pollutants
- Paranasal sinuses: Air-filled spaces within the skull (frontal, maxillary, ethmoid, sphenoid), that help with sound resonance
- Pharynx: Funnel-shaped tube extending from nose to larynx
- Larynx: Voice box; acts as a clearance mechanism (cough)
- Trachea: Windpipe
- Carina: Point where trachea divides into the right and left main bronchi
- Cilia: Microscopic hair-like structures that move in a coordinated way to push out debris
- Right main bronchus: Right bronchus is wider and shorter than left.
- Left main bronchus: Left bronchus is narrower and longer
Respiratory Structures - Lower Airways
- Lower airways: Trachea, bronchi, bronchioles, and alveoli
- Trachea (windpipe): Tube-like structure where air passes to the lower airways
- Bronchial tubes (bronchi): Tubes that branch from the trachea
- Bronchioles: Smaller branches of the bronchial tubes
- Alveoli: Sac-like structures in the lungs where gas exchange occurs. Air sacs
Respiratory Processes
- Ventilation: Movement of gases into and out of the lungs (inspiration and expiration)
- Inhalation: Air moves into the lungs
- Exhalation: Air moves out of the lungs, involuntary process.
- Diffusion: Exchange of gases from an area of higher pressure to an area of lower pressure. Oxygen moves from the air into the blood, and carbon dioxide moves from the blood into the air.
- Perfusion: Availability and movement of blood to facilitate gas exchange. Blood carries gases, nutrients and waste products.
Dyspnea
- Difficulty breathing , can be acute (sudden onset) or chronic (persistent).
- Mild: Moderate difficulty breathing
- Chronic: Persistent breathing problems over a long time
- Severe: Significant difficulty breathing.
Respiration
- The process of gaseous exchange between the body and its environment (inhaling oxygen, exhaling carbon dioxide).
Other important notes
- The respiratory system is crucial for life.
- Breathing is a synonymous to life.
- The lungs are responsible for gaseous exchange.
- Various respiratory structures form a pathway for air.
