Respiratory System in Humans
- The human respiratory system is divisible into two portions:
- Conducting Portion:
- Nose
- Pharynx
- Larynx
- Trachea
- Bronchi
- Lobular and terminal bronchioles
- Respiratory Portion:
- Respiratory bronchioles
- Alveolar ducts
- Alveolar sacs and alveoli
- Conducting Portion:
- There is a pair of external nostrils opening out above the upper lips. It leads to a nasal chamber through the nasal passage.
- The nasal chamber opens into the pharynx.
- The pharynx opens through the larynx region into the trachea.
- The larynx is a cartilaginous box which helps in sound production and hence called the soundbox.Larynx is made up of 9 cartilages out of which three are paired and three are unpaired
- During swallowing, glottis can be covered by a thin elastic cartilaginous flap called the epiglottis to prevent the entry of food into the larynx.
- The trachea is a straight tube extending up to the mid-thoracic cavity, which divides at the level of 5th thoracic vertebra into a right and left primary bronchi.
- Each bronchus undergoes repeated divisions to form the secondary and tertiary bronchi and bronchioles ending up in very thin terminal bronchioles.
- The tracheae, primary, secondary and tertiary bronchi, and initial bronchioles are supported by incomplete cartilaginous rings.
- Each terminal bronchiole gives rise to a number of very thin, irregular-walled and vascularised bag-like structures called alveoli.
- The branching network of bronchi, bronchioles and alveoli comprise the lungs.
