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 surgical cut is usually made in the middle of the abdomen. The bowel resection or repair is done as needed. For the colostomy, one end of the healthy colon is brought out through an opening made in the abdomen wall, usually on the left side. The edges of bowel are stitched to the skin of opening. This opening is called a stoma. A bag called a stoma appliance is placed around the opening to allow stool to drain. Your colostomy may be short-term. If you have surgery on part of your large intestine, a colostomy allows the other part of your intestine to rest while you recover.
