cilia
How does it work(and explain about Cilia)
- cilia(singular, cilium) are relatively long, slender extensions of the cell membrane. they are found on cells lining the respiratory tract, on cells lining the reproductive tract, and at various other locations in the body. cilia have an internal arrangement similar to that of centrioles. However, in cilia, nine pairs of microtubules(rather than triplets) surround a nine pair of microtubules ( rather than triplet
- The Microtubules are anchored to a compact basal body situated just beneath the cell surface. the organization of microtubules in the basal body resembles the 9 +0 array of a centriole: nine triplets with no central pair.
- Cilia are important because the y can'' beat''rhythmically to move fluids or secretions across the cell surface the cilium is relatively stiff during the effective power stroke and flexible during the return stroke.
- ciliated cells along your trachea beat their cilia in synchronized waves to move sticky mucus and trapped dust particles toward the throat and away from delicate respiratory surfaces. if the cilia are damaged or immobilized by heavy smoking or a metabolic problem, the cleansing action is lost and the irritants will no longer be removed. As a result, a chronic cough and respiratory infections develop. ciliated cells also move oocytes along the uterine tubes, and waft sperm from the testes into the male reproductive tract.
- cilia, anchored by aa basal body, beat rhythmically to move fluids or secretions across the cell surface
why cilia is important?
- Cilia traps debris from entering our body. It works by moving "back and forth" pushing foreign matter out. For example our respiratory system, cilia is found in the trachea and traps the debris from entering our lungs.
- cilia is used to increase the surface area available for oxygen absorption, while in the reproductive system it can be used to help more efficiently transport sperm.
