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.
At the top of the trachea the cricoid cartilage attaches it to the larynx. This is the only complete ring, the others being incomplete rings of reinforcing cartilage. The trachealis muscle joins the ends of the rings and these are joined vertically by bands of fibrous connective tissue, the annular ligaments of trachea.The epiglottis closes the opening to the larynx during swallowing.The trachea develops in the second month of development. It is lined with an epithelium that has goblet cells which produce protective mucins. An inflammatory condition, also involving the larynx and bronchi, called croup can result in a barking cough.his is the only complete ring, the others being incomplete rings of reinforcing cartilage.
