NEET BIOLOGY

Detailed explanation-1: -The bronchus in the lungs are lined with hair-like projections called cilia that move microbes and debris up and out of the airways.

Detailed explanation-2: -Ciliary movement is referred to as the rhythmic movement of cilia, which causes movement of the fluid or the cell. Cilia are found in eukaryotic cells. An example is in Paramoecium, ciliary movement helps in the movement of the cell which is locomotion as well as in the movement of the food inside the cell.

Detailed explanation-3: -Cilia are little appendages that stick out from eukaryotic cells. They whip back and forth and help cells move around in cellular fluids. They also help particles move past the cell.

Detailed explanation-4: -The motile cilia found in the lungs, respiratory tract and middle ear of a human body prevent dust and mucus in the airways and facilitate the movement of sperms and eggs.

Detailed explanation-5: -Cilia and flagella are microtubule (MT)-based organelles that extend from the surface of eukaryotic cells. Ciliary and flagellar movements are generated by MT sliding with axonemal dynein motors and play important roles in cell migration and generation of external fluid flow.
