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.
This holder often is a strap that fits around the head. Sometimes the breathing tube is placed through a surgically made hole called a tracheostomy (TRA-ke-OS-to-me). The hole goes through the front of your neck and into your windpipe. The tube put into the hole sometimes is called a trach tube. The procedure to make a tracheostomy usually is done in an operating room. Anesthesia is used, so you won't be awake or feel any pain.
