Study Notes

Human Respiratory System

The respiratory system enables breathing and comprises the nose, nasal cavities, pharynx, larynx, trachea, bronchi, bronchioles, and alveoli.

Nose and Nasal Cavities

The nose is the only visible part of the respiratory system, consisting of bones, cartilage, and fibro fatty tissues.
The appearance of the human nose is influenced by the ethmoid bone and the cartilages.
Nose hairs filter incoming air, acting as a defense mechanism against pathogens and particulate matter.
Both nostrils and nasal cavities are lined with mucous membranes and cilia that play a crucial role in air filtration.
Mucous membranes produce mucus, a sticky substance that traps foreign particles like microorganisms and dust.
Cilia work alongside mucus to help clear out trapped particles, preventing them from entering the lower respiratory tract.
