Epithelium Ciliated

The ciliated epithelium is one of the important types of cells in the structure of the skin. It has a number of features that distinguish it from other types of epithelium.

What are ciliated cells? Ciliated cells (cilia and flagella) are found in the deep layers of the skin, on the mucous membranes and in the bronchi. They range from 4 to 30 micrometers in length and are made up of long filaments called microvilli or cilia. The cilia are covered with mucus and are designed to move dust, small particles, bacteria and other microscopic particles. Together they form ciliated plankton in the body.

Ciliated epithelium is one of the types of multilayered human tissues. Multilayer tissues consist of several layers of cells. In the ciliated epithelium, cells are arranged in several layers, and each layer moves in one direction. Typically, this direction is from the skin outward. This type of tissue is found in the human respiratory tract: bronchi and trachea, in the nasal cavity, paranasal sinuses, etc. The surface of the ciliated epithelium is covered with specialized cells - cilia. These cilia create air currents inside the cells, which promotes air movement. This is very important to ensure that the cilia do not come into contact with foreign elements or bacteria. The epithelium also has features in the form of proteins on the surface that make the cilia more mobile. When you have a cold, these proteins may fall out, but usually they are restored if the person is healthy and the treatment is carried out correctly. In addition, eyelashes help get rid of dust and other air pollutants.

Ciliated epithelium is epithelial tissue that contains cells that have cilia and facilitate the movement of secretions from the sensory organs in the body cavity. Its function is to transport substances in and out of the body. Cilia are microscopic structures consisting of membrane protein and dendrites. They create an impulse that causes movement of epithelial cells.

Ciliated epithelium exists throughout the human body. It covers the respiratory system, gastrointestinal tract, urinary tract and genitals. In each of these organons it performs its own special functions. For example, in the respiratory system, the ciliated epithelium in the lungs performs the function of air purification. This process occurs by rapid movement of the epithelial cilia and expulsion of bacteria and dust from the alveoli of the lungs. In the stomach and intestines, the epithelium also plays an important role in protecting the body from harmful microorganisms and toxins. Epithelial cilia quickly move along the intestine, capturing and removing metabolic products from the intestinal walls. In addition, it contains special cells called enterocytes that absorb nutrients and transport them into the blood for delivery to other organs.
