maybe trachea??
The opening into the trachea is called the tracheal orifice, or alternatively, the opening can also be referred to as the tracheal inlet. This is where air enters the trachea from the upper respiratory tract, allowing for the passage of air into the lungs for respiration.
The pericardial sac is lined with a double-layered membrane called the serous pericardium. The inner layer is the visceral pericardium (or epicardium) which is in contact with the heart, and the outer layer is the parietal pericardium which is attached to the surrounding structures.
The inside of the body is lined with a protective layer called the epithelium. This layer covers organs, blood vessels, and other internal structures to provide a barrier and regulate the exchange of substances between different body compartments.
The trachea, also known as the windpipe, is responsible for carrying air to and from the lungs. It is lined with a mucous membrane that helps to trap any dust or particles in the air before it reaches the lungs, protecting the respiratory system. The trachea also contains C-shaped rings of cartilage which provide structure and prevent it from collapsing.
The trachea is lined with cilia, which are tiny hair-like structures that beat in a coordinated manner to sweep away particles and dust trapped in mucus towards the throat where they can be expelled by coughing or swallowing.
Both the human and grasshopper respiratory systems have structures called trachea that are lined with epithelial cells.
The trachea is lined with ciliated columnar epithelium, which has hundreds of tiny hairs called cilia.
They are called Alveoli.
The turbinates are the bony structures inside the nose that help moisten and filter the air before it enters the trachea. They are lined with mucous membranes that trap particles and add moisture to the air.
The trachea is lined with a moist mucous-membrane layer made up of cells containing small hairs called cilia. The cilia project into the channel (lumen) of the trachea to trap particles. There are also cells and ducts in the mucous-membrane that secrete mucus droplets and water molecules.Cilia are whiplike, motile cellular extensions that occur, typically in large numbers, on exposed surfaces of certain cells. In the trachea, ciliated cells that line the respiratory tract propel mucus laden with dust particle and bacteria upward away from the lungs. Centrioles, referred to as basal bodies, are the originating source of cilia.

Your fallopian tubes are lined with tiny hair-like structures called cilia which are constantly swaying back and forth to help guide the egg and push it along to the uterus :)
The opening into the trachea is called the tracheal orifice, or alternatively, the opening can also be referred to as the tracheal inlet. This is where air enters the trachea from the upper respiratory tract, allowing for the passage of air into the lungs for respiration.
The tube is known as the trachea, or windpipe. It serves as a passageway for air to travel in and out of the lungs. The rings of cartilage help keep the trachea open, while the cilia and mucous membrane function to trap and remove any foreign particles or debris from the air before it reaches the lungs.
The pig esophagus is lined with a stratified squamous epithelium designed for food transport and protection from abrasion, while the trachea is composed of cartilage rings and lined with pseudostratified ciliated columnar epithelium to facilitate air passage and filtration. The esophagus lacks cartilage support, has a mucus-secreting submucosa, and undergoes peristalsis to move food to the stomach, unlike the trachea.
