  The respiratory system is a system of the body that deals with breathing. It takes in oxygen that it needs, and removes the carbon dioxide it does not need. It starts off by inhaling, through the nose or mouth. It then travels through the trachea, other wise known as the windpipe, which looks like rings of cartilage. The trachea then breaks into two tubes called bronchi, which deliver air into each lung. Inside each lung are tubes that become smaller tubes known as bronchioles. At the end of each bronchiole are alveoli. Wrapped around the alveoli are capillaries, which are small blood vessels. The alveoli are so thin that air is able to seep through them. The oxygen inhaled that came from the capillaries, seeps into the bloodstream. During that same period of time, the carbon dioxide seeps into the alveoli and then departs from the body by the process of exhaling. To help the breathing course the diaphragm, a muscle that controls the breathing process, is used. When it contracts the lungs and chest expand and air flows into the lungs. Once it relaxes, the lungs deflate and the chest collapses, while the air then exits out of the lungs. This is the normal pattern of the respiratory system.

 The diagram above is of the human respiratory system.

Below is an up close diagram of the different parts of a human's lungs.

 Above is a diagram of the process of inhaling and exhaling. When a person inhales the chest expands and the diaphragm contracts. The chest and diaphragm relax when a person exhales.

Below is an animation of the lungs and diaphragm doing their part in the respiratory system.
