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.
Types of Tracheostomy Tubes. A tracheostomy (trach) tube is a curved tube that is inserted into a tracheostomy stoma (the hole made in the neck and windpipe (Trachea)). There are different types of tracheostomy tubes that vary in certain features for different purposes. These are manufactured by different companies. However, a specific type of tracheostomy tube will be the same no matter which company manufactures them. A commonly used tracheostomy tube consists of three parts: outer cannula with flange (neck plate), inner cannula, and an obturator.
