Hairs and mucus
In the lining of the respiratory tract.
The respiratory tract contains the ciliary escalator which is a mechanism where cilia in the respiratory tract lining help to remove particles and pathogens by moving them upwards towards the throat to be swallowed or expelled.
The tissue lining your inner nasal passages is made from ectoderm. However, the rest of the respiratory tract lining is made of endoderm.
The medical term for thin hairs attached to the mucous membrane lining the respiratory tract is "cilia." Cilia help to move mucus and foreign particles out of the airways to keep the respiratory system healthy and functioning properly.
Cilia are found in the lining of the trachea.
Ciliary dysfunction in the epithelial lining of the respiratory tract is responsible for the smoker's cough. Smoking damages the cilia, which are tiny hairs that help to move mucus and debris out of the airways. When cilia are impaired, mucus and irritants accumulate, leading to coughing as the body tries to expel them.

Mucus serves to protect and lubricate the body's tissues, such as the lining of the respiratory tract and digestive system. It helps to trap and remove foreign particles, bacteria, and viruses.

Phlegm is the thick mucus and sputum the material coughed up from the lining of the respiratory tract.
Cilia are the microscopic hairlike projections found in the cells lining most of the respiratory tract. They help to sweep mucus and trapped particles out of the airways to protect the lungs from infections and irritants.
Mucus is produced by specialized cells called goblet cells that are found in the lining of various organs such as the respiratory tract, digestive tract, and reproductive system. These cells secrete mucus, which helps to lubricate and protect the lining of these organs.
