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.
What is a Tracheostomy? A tracheostomy (trach) is a surgical procedure in which a doctor creates an opening (stoma) in the front of your neck into your windpipe. This opening allows air to flow in and out of your lungs. A small curved, plastic tube (tracheostomy tube) is then placed into the stoma. This tube serves as a pathway to make breathing and the clearing of secretions easier, and as a way to keep the stoma open. Back to top.
