Mucociliary streaming is the process of the cleaning mechanism of the respiratory passage. It is one of the protective process that protects the respiratory passage from the effect of the particles of dust and pathogens before they reach up to the delicate lung tissues. This process maintains the pulmonary hygiene.
This takes the advantage of cleaning up the cilia present in the respiratory tract, this process penetrates the mucous layer of the cilia by wave-like motion. The cilia trap the large and small particles. The instrument used for this purpose moves at a speed of 6 to 20mm per minute. This helps in cleaning up of the cilia along with the mucous.

Explanation:
Reproduction is the process by which living organisms multiply themselves. They do this through two major ways namely: asexually and sexually. Sexual reproduction involves two organisms (male and female) that each donate a gamete (sperm and egg). In plants, the sexual reproductive structure is the FLOWER. The male flower is called STAMEN, while the female flower is called PISTIL.
