The tissue lining your inner nasal passages is made from ectoderm. However, the rest of the respiratory tract lining is made of endoderm.
The membrane that lines most of the air distribution tubes of the upper respiratory system is called the respiratory mucosa. This mucosa is a specialized epithelial tissue that contains goblet cells, which produce mucus to trap particles and pathogens, and cilia that help move the mucus out of the respiratory tract. It plays a crucial role in warming, humidifying, and filtering the air we breathe.
The respiratory tract membrane primarily consists of epithelial tissue and connective tissue. The epithelial tissue is typically pseudostratified ciliated columnar epithelium, which helps in mucus secretion and trapping particles. Beneath this, the connective tissue provides structural support and houses blood vessels and immune cells. Together, these tissues facilitate the functions of gas exchange and protection in the respiratory system.
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.
The three most common are the skin, gastrointestinal tract and respiratory tract

Epithelial tissue lines the stomach, like most internal organs.
Epithelia tissue lines all the body's surfaces and cavities.It is found on the surface of the body (skin) and lines the entire digestive tract, reproduction tract, respiratory track and lungs, excretory system, and endocrine system.Epithelia tissues that line the spaces of the body that are not directly open to the outside of the body such as the lymphatic system, blood system, and endocrine system is called endothelium. (Endothelia is a type of epithelia tissue by definition.)
Pseudostratified ciliated columnar epithelium lines most of the respiratory tract. This type of epithelium helps to trap foreign particles and move them out of the respiratory system with the help of cilia.
All parts of the skin is affected in Chickenpox. Although most of them are in the trunk area of the patient. But the lesions can be everywhere.
Organisms can enter through the gastrointestinal tract,respiratory tract,genitourinary tract or even through the cutaneous route.
Most definitely yes. A semisynthetic analog of cephalosporin, it attacks Gram negative bacteria. It's used frequently for upper respiratory and urinary tract infections, but also has wide spectrum applications.
The respiratory system is most vulnerable to sulfur mustard exposure. When sulfur mustard is inhaled, it can damage the respiratory tract, causing inflammation, blistering, and potentially leading to respiratory failure.
