At the top of the respiratory system, the nostrils (also called nares) act as the air intake, bringing air into the nose, where it's warmed and humidified. Tiny hairs called cilia protect the nasal passageways and other parts of the respiratory tract, filtering out dust and other particles that enter the nose through the breathed air.

Cells lining the bronchus produce mucus that traps particles and pathogens, preventing them from reaching the alveoli. Cilia on the bronchial cells then move the trapped particles and mucus away from the alveoli, protecting them from damage or infection. Additionally, the bronchial cells secrete antimicrobial substances to further defend the alveoli against infection.

What has a single layer of epithelial cells?
Simple Squamous epithelial cells are found in the lung (alveoli), lining the lumen of blood vessels, and lymphatic vessels, and also in the kidneys.
Where is mucous made?
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.
How long do stomach lining cells live?
Stomach lining cells typically live for around 3 to 7 days before being replaced. The rapid turnover of these cells helps protect the stomach from the strong acids and enzymes it produces for digestion.
The lining of the coelom is called?
The lining of the coelom is called the mesothelium. It is a thin layer of cells that surrounds the coelomic cavity and helps to support and protect the organs within it.
What tissue is microvilli and goblet cells associated with?
Microvilli are associated with the epithelial tissue lining the small intestine, where they increase surface area for absorption. Goblet cells are specialized cells found in the epithelial tissue of the respiratory and digestive tracts, where they secrete mucus to protect and lubricate the lining of these organs.
How do the cells lining the bronchus protect the alveoli from damage?
I think that it protects them because they like swish them about and make them covered by a mucusy layer which then protects them further called bronchilus. this eventully stops any damage at all in the alveoli
What does the stem bronchus in the lungs do?
It sends oxygen to individual alveoli in your lungs, which sends oxygen to your body's cells.
What function of the Bronchus?
The function of the bronchus is to split up the air coming into the right and left lungEach bronchiole ends in a cluster of air sacs called alveoli. In the alveoli gases are exchanged during respiration. bronchus(bronchi-plural) held open by cartilage, they convey air into each lung. The bronchi are lined with mucous membrane and ciliated cells which trap and help in the removal of any dirt and dust that enters
What is the scientific name for lung cells?
Pneumocyte. There are two types: Type I cells make up the lining of the air sacks (alveoli) in the lung, type II cells produce a slick liquid called surfactant that helps coat the alveoli and keep them from collapsing when we exhale.
What has a single layer of epithelial cells?
Simple Squamous epithelial cells are found in the lung (alveoli), lining the lumen of blood vessels, and lymphatic vessels, and also in the kidneys.
Where is mucous made?
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.
What is the pathway of the blood flow through the heart and lungs in order to get oxygen?
In air through the passageways to the lungs, by diffusion through the alveoli into the blood, by diffusion out of the blood into the cells and through the cells into the mitochondria - where it ceases to exist as oxygen and becomes water.
Where are stem cells that make new cells to protect the intestines in adults?
in the bones
How long do stomach lining cells live?
Stomach lining cells typically live for around 3 to 7 days before being replaced. The rapid turnover of these cells helps protect the stomach from the strong acids and enzymes it produces for digestion.
What two places are goblet cells found?
Goblet cells are found in the respiratory tract, especially in the bronchi and bronchioles, where they produce mucus to protect and lubricate the airways. They are also present in the gastrointestinal tract, lining the mucosa of the intestines to secrete mucus that aids in digestion and protects the lining from injury.
What do the cells lining the nose do?
The cells lining the nose are called mucus which are considered as specialized cells. These are important because they prevent pollutants from invading and irritating the organs ...so they're there to protect us from infections etc Hope it helped.
How does the stomach survive with one ML of HCL in it?
The stomach is lined with a thick layer of mucus that helps protect its lining from the corrosive effects of hydrochloric acid (HCl). The mucus acts as a barrier, preventing the acid from damaging the stomach tissue. Additionally, the stomach has a rapid turnover of its lining cells, allowing damaged cells to be quickly replaced.
