The Respiratory System includes the following organs:
Nose
Mouth
Throat (pharynx)
Voice box (larynx)
Windpipe (trachea)
Large airways (bronchi)
Small airways (bronchioles)
Lungs
TRACHEA Epithelium: Pseudostratified Columnar 3 main cell types: Goblet cells, Basal Cells, Cilia The TRACHEA is a long tube that connects to the voicebox and then to the Bronchi. It is a key part of the respiratory system as it functions as the windpipe. When the air goes to the trachea, it goes to the bronchi and then carries it towards the lungs. With the help of the Goblet cells, it helps secret mucus to maintain moisture and trap pathogens or debris away from the airway. The basal cells help in restoring a healthy layer of the epithelium. Cilia are tiny hairs that carry mucus in and out of the respiratory tract. It also functions as a filter to keep out dust or pathogens away from the airway tract.
LUNGS Epithelium: Ciliated Pseudostratified Columnar epithelium The lungs are covered by a thin-double layered serous membrane known as Pleura. It functions to remove oxygen distributing it to the bloodstream
EPIGLOTTIS Epithelium: Stratified Squamous non-Keratinized The Epiglottis is like a leaf-shaped flap located at the base of the tongue. It prevents food in going to the trachea. However, if this gets infected, it can cause blockage of the windpipe making it hard or unable to breathe.
Moreover, the respiratory tract is divided into two. The upper and lower respiratory tract. The upper respiratory tract includes: Nose Nasal cavity Sinuses Larynx Trachea The lower respiratory tract is consists of: Lungs Bronchi and bronchioles Air sacs (alveoli)
