Come Hell or High Water. The worst damage from floods, the loss of life and homes, is caused primarily by the sheer force of flowing water. In a flood, two feet (61 cm) of water can move with enough force to wash a car away, and 6 inches (15 cm) of water can knock you off your feet.ince there is a great deal of water collected in one area, flash-flood waters tend to move with a great deal of force, knocking people, cars and even houses out of the way. Flash floods can be particularly devastating when a heavy thunderstorm dumps a high volume of rain on a mountain.
The trachea is reinforced with cartilaginous rings in order to retain the shape while breathing and the rings are incomplete to allow the trachea to expand and move when food â¦ passes through the esophagus and while bending the neck.5 people found this useful.hey are C-shaped, with the opening in the back so that when you swallow food, the esophagus expands into the area of the trachea to allow the food (called a bolus) to go down â¦ . This process is called deglutition.
This lesson will describe the function and basic anatomy of your trachea, which is an important structure within your respiratory system. A post-lesson quiz will test what you have learned.
