Will Wheeler Respiratory System Organ Functions Nose Keeps the blood continuously supplied with oxygen while removing carbon dioxide The NOSE is the preferred entrance for outside air and the respiratory system.The nose helps you smell.
The PHARYNX opens into two passageways which is a common passageway for air and food.
The LARYNX most important function is to prevent choking.
The TRACHEA is known as the windpipe and its function is to help with air flow.
The BRONCHI job is to allow air to pass and preventing infection.
The purpose of the LUNGS is for oxygen to enter the body while removing carbon dioxide. The main function of the nose is to help us breathe. When we inhale through our nose, air passes through our nostrils into a short and narrow area known as the nasal passage that leads to the back of the throat (pharynx), and on down into the windpipe and lungs. From there it continues throughout the respiratory system.The main function of the nose is to help us breathe. When we inhale through our nose, air passes through our nostrils into a narrow area known as the nasal passage that leads to the back of the throat, and on down into the windpipe and lungs.
MAIN FUNCTION: to supply the blood with oxygen in order for the blood to deliver oxygen to all parts of the body. The respiratory system does this through breathing. When we breathe, we inhale oxygen and exhale carbon dioxide. This exchange of gases is the respiratory system's means of getting oxygen to the blood. Respiratory System Block 1 Pharynx Pharynx is a tube like structure that connects the nasal and oral cavities to the larynx. Pharynx is nothing but throat. The function of the pharynx is to provide a passageway for the respiratory and digestive tracts. The role of pharynx is very important in our human body because it has to coordinate both inspiration and swallowing while eating, otherwise may lead to aspiration and death. Larynx The larynx (sometimes called the voice box) is a tube-shaped organ in the neck region between the pharynx (throat) and the trachea (breathing tube). The larynx houses the vocal cords and has a cartilaginous skeleton and intrinsic and extrinsic muscles that help it to carry out its primary functions, which include voice production, control of airflow (breathing) and swallowing.

l Bronchi One of the primary function of bronchi is to allow air to pass through it. As the trachea splits into two parts, the inhaled air then enters the bronchi. From here, it passes through the further divisions of the bronchi, which are known as bronchioles. The bronchioles then divides to form alveolar ducts which eventually end into alveolar air sacs or alveoli. The bronchi are a complex system of airway tubes that carry air into and out of the lungs. The bronchi do not absorb oxygen or exchange it for carbon dioxide; gas exchange only occurs in the alveolar sacs at the very ends of the bronchial network. Lungs The function of the lungs is to receive air from the atmosphere through the nose and mouth with every inhale, and allows the transfer of the oxygen in the air to pass into the blood stream. Lungs store the body's oxygen supply and they are the pumps that push air around and out of the body. The lungs also filters out the carbon dioxide and adds oxygen to it, turning it into oxygenated blood. The blood you see through your skin is the blood with carbon dioxide. Asthma Asthma is a disorder that deals with the lungs. There are more than 22 million Americans who have asthma. Most of the time people are born with asthma and diagnosed at a early age. It can be passed down from generation to generation.The inside walls of an asthmatic's airways are swollen or inflamed. This swelling or inflammation makes the airways extremely sensitive to irritations. Asthma (continued) Symptoms of asthma include wheezing (a hissing sound while breathing), chest tightness, breathing problems, and coughing. Asthmatics usually experience these symptoms most frequently during the night and the early morning. Asthma can be deadly if you have an asthma attack you can die. Asthma messes up your breathing where you can go into cardiac arrest or could die from no air is passing through. Also you can pass out if you have an Asthma attack. There is no cure but you can live a long, healthy life with it. Citation Page

It is a bony tube, which connects the nose and mouth to the lungs, and is an important part of the respiratory system in vertebrates. The primary function of the trachea is letting of the air flow into the lungs. Any damage to the trachea which causes its collapse or blockage interferes in normal exchange of the previously mentioned air and if not treated urgently leads to death.
