RESPIRATION IN HUMAN BEING

Respiratory tract includes external nostrils nasal cavities, pharynx larynx & trachea. Respiratory tract is not concerned with the gaseous exchange. Trachea has rings of cartilage that prevent collapse of trachea.

Respiratory organs are lungs which provide surface for exchange of gases. Lungs are pair in number, and lies in thoracic cavity. Lungs remain enclosed by pleura.
