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.
