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 walls of the trachea are composed of connective tissue and smooth muscle. A number of C-shaped rings of cartilage, usually between 15 and 20, are contained in the tracheal wall. The C shape is open to the rear of the windpipe due to its nearness to the esophagus. This allows the esophagus to expand toward the front of the throat when food passes through it. The rings of cartilage also keep the trachea from collapsing due changes in air pressure that normally occur during respiration.
