Name _________________. Overview. In this activity, you will study the effects of gravity on the planets of the Solar System. First, you need to view movies from the lunar Apollo missions, then calculate your weight on other planets. Finally, you will propose your weight on newly discovered planets around other stars.
A tracheostomy is an opening cut into the windpipe, or trachea. It is used as an airway for breathing. After the opening is made, a small tube is inserted to let air in, and to attach a breathing machine (mechanical ventilator) if needed.
The translaryngeal tracheostomy is a percutaneous technique characterized by the exclusive procedure to carry out the stoma. A cone of soft plastic material, welded to a flexible cannula, is passed into trachea through the glottis, and then extracted outside of the neck through the pretracheal layers.
