Wavelength. 1  Frequency tells us how many waves are passing a point per second, the inverse of time. 2  Wavelength tells us the length of those waves in metres, almost like a displacement. 3  If we multiply these two together, we are really multiplying 1/s and mâ¦ which gives us m/s, the velocity of the wave!
Best Answer: Connective tissue function:- The cartilage rings support the trachea and prevent it from collapsing when air is taken in. Epithelial Tissue function:- The ciliated epithelium cleans out the particulate material in the air before it enters the lungs.
the 3rd tracheal ring, it can be bluntly undermined and retracted superiorly to gain access to the trachea. If the isthmus overlies the 2nd and 3rd ring of the trachea, it must be mobilized and either a small incision made to clear a space for the tracheostomy (Fig. 2) or complete Fig. 1. Creating a surgical tracheostomy. After incising the skin
