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.
A tracheostomy is a surgically made hole that goes through the front of your neck into your trachea, or windpipe. A breathing tube, called a trach tube, is placed through the hole and directly into your windpipe to help you breathe. A tracheostomy may be used to help people who need to be on ventilators for more than a couple of weeks or who have conditions that block the upper airways.
