Respiratory System

 * 1. The respiratory system is made of body parts that are in charge of your breathing. Two major muscle groups are used in the normal breathing process: the diaphragm and the rib muscles.The lungs are the main organs of the respiratory system. In the lungs oxygen is taken into the body and carbon dioxide is breathed out. The red blood cells are responsible for picking up the oxygen in the lungs and carrying the oxygen to all the body cells that need it. The red blood cells drop off the oxygen to the body cells, then pick up the carbon dioxide which is a waste gas product produced by our cells. The red blood cells transport the carbon dioxide back to the lungs and we breathe it out when we exhale . || [[image:http://hes.ucfsd.org/gclaypo/images/ressys.gif width="227" height="300" align="bottom"]][[image:http://hes.ucfsd.org/gclaypo/images/diaphragm.gif width="188" height="165" align="bottom"]] ||

The tissue that covers the wall of your nasal cavity contains many blood vessels. Heat from the blood in the vessels helps warm the air as you breath. Moisture is added to the air you breath by special cells in the walls of the nasal cavity. The trachea is sometimes called the windpipe. The trachea filters the air we breathe and branches into the bronchi. The trachea is surrounded by bands of cartilaginous tissue to prevent it collapsing in on itself, which would then cut-off our airway and prevent us from breathing. These cartilagenous ring are C shaped and are meant for particular purposes such as they give support and strength to the trachea, also cartilage contain much collagen fibres which are stress resistant they don't allow the trachea to shrink. The bronchi are two air tubes that branch off of the trachea and carry air directly into the lungs. Breathing starts with a dome-shaped muscle at the bottom of the lungs called the diaphragm. When you breathe in, the diaphragm contracts. When it contracts it flattens out and pulls downward. This movement enlarges the space that the lungs are in. This larger space pulls air into the lungs. When you breathe out, the diaphragm expands reducing the amount of space for the lungs and forcing air out. The diaphragm is the main muscle used in breathing.
 * You inhale air though your nose. As you inhale small specks of dirt are trapped by many tiny hairs in your nose. This cleans the air. The hairs stop the dirt from going further in your body. The moist inside surface in your nose traps even smaller pieces of dirt. The nasal cavity, the air passage behind the nose, plays an important role in breathing.

The basic function of alveoli is gas exchange. The alveoli structure is the site where the gaseous exchange during respiration takes place. These structures are surrounded by capillaries carrying blood. The exchange of carbon dioxide in the blood from these capillaries occurs through the walls of alveolus.The Alveoli has a moist lining, Because the gases must be dissolved in water in order to get through the walls. || === 2. Enzymes and hormones: All your body cells depend upon enzymes to help them run the chemical reactions they need to in order to maintain function. Some enzymes in the respiratory system are specific to that system, and others are more generalized in function. === === Carbonic Anhydrase- This enzyme is specific to the respiratory system. The role of Carbonic Anyhdrasse is to combine cabon dioxide and water to form carbonic acid. This allows carbon dioxide to move through the blood and into the lungs. === === Angiotensin- Converting Enzyme - This enzyme is also specific to the respiratory system. ACE helps maintain a constant volume of fluid outside of the cells in the body. It's called a converting enzyme because it converts angiotensin I to angiotensin II. === === 3. Air flow in the lungs is controlled by the nervous system, because of this, we breathe at a steady and constant rate. There are certain hormones like adrenalin which help stimulate respiratory activity. Endocrine hormones also important. They effect the dilation of the alveoli which impacts the amount of oxygen being absorbed by the lungs. ===

===4. Communication: In the Digestive System breaks down food so the body can get nutrients. The Respiratory System uses this nutrients for the lungs. And vise versa the Respiratory System gives oxygen to the Digestive System. The Skeletal System helps protect the lungs in the Respiratory System. In the Circulatory System helps clean the lungs and keeps it healthy. Vise Versa the Respiratory System helps keep air flowing.The Muscular System pushes air through the Respiratory System by the contraction and relaxtation of the diaphragm. The Respiratory System uses the lungs to deliver the air to the muscles. The Nervous System relates to the Respiratory System by allowing you to feel that you have control of your breathing. ===
