Respiratory System Overview
- The respiratory system is responsible for breathing
- Air enters through the nose and mouth
- It's cleaned, warmed, and moistened before reaching the lungs
Nasal Cavity
- Hollow spaces that filter, warm, and moisten air
- Part of the breathing process
Mouth
- Another entry point for air
- Can also humidify and filter air particles
Pharynx
- Also known as the throat
- Chamber for food and air
Larynx
- Hollow organ connecting the throat to the trachea
- Contains vocal cords (voice box)
Trachea
- Often called the windpipe
- Tube connecting the mouth/nose to the lungs
- Helps with breathing and talking
Bronchi
- Branches of the trachea
- Located within the lungs
- Allow air to travel deeper into the lungs
Bronchioles
- Narrow tubes branching off the bronchi
- Further divide the bronchial network
Lungs
- Extract oxygen when inhaling
- Release carbon dioxide when exhaling
- Main organs of the respiratory system
Diaphragm
- Dome-shaped muscle
- Helps with breathing by expanding and contracting the lungs
Alveoli
- Tiny air sacs in the lungs
- Where oxygen enters and carbon dioxide exits the bloodstream
