The Function Of The Respiratory System

The way the Respiratory System works is complicated . It also is surprisingly fast in what it does. First the Diaphragm moves downwards which causes the lungs to expand creating a vacuum for air . Air enters the mouth or nose and goes through the Pharynx and into the Larynx to the vocal cords .The air then goes down the Trachea and into two Bronchi which feed into the lungs .Then air reaches tiny little itty bitty sacs called Alveoli .Which pass oxygen into the bloodstream.When the Diaphragm moves upwards air moves out the lungs up the Trachea through the Pharynx and out the mouth or

Exhalation, (breathing out), is the opposite of inhalation and occurs when the inspiratory muscles relax causing the diaphragm to depress which decreases the lung volume. This decrease in volume causes the alveolar pressure to increase therefore the carbon dioxide in the lungs flows from a high pressure to a lower pressure in the atmosphere. (Tortora & Derrickson, 2011)

The respiratory system’s organs bring in oxygen by inhaling and remove carbon dioxide by exhaling. Oxygen travels through the trachea, pharynx, bronchi, bronchioles, and alveoli. At the alveoli gas exchange occurs in which oxygen diffuses into the bloodstream of the circulatory system, and carbon dioxide is removed from the bloodstream and exhaled. The close connection of these two body systems is important to note when analyzing the effects of smoking on each system separately.

Gas exchange is when oxygen is delivered from the lungs to the blood stream and carbon dioxide is taken out of the bloodstream and into the lungs. Gas exchange occurs within the lungs between the alveoli and capillaries which are in the walls of the alveoli. The walls of the alveoli share a membrane with the capillaries in which oxygen and carbon dioxide move freely between the respiratory system and the bloodstream. Oxygen molecules attach to red blood cells, which travel back to the heart. At the same time, the carbon dioxide in the alveoli are exhaled out of the body.

➢ Inhaled air enters the nasal cavity, where it is cleaned, warmed and humidified on its way through the pharynx.

The respiratory system is a complex organ structure of the human body anatomy, and the primary purpose of this system is to supply the blood with oxygen in order for the blood vessels to carry the precious gaseous element to all parts of the body to accomplish cell respiration. The respiratory system completes this important function of breathing throughout inspiration. In the breathing process inhaling oxygen is essential for cells to metabolize nutrients and carry out some other tasks, but it must occur simultaneously with exhaling when the carbon dioxide is excreted, this exchange of gases is the respiratory system's means of getting oxygen to the blood (McGowan, Jefferies & Turley, 2004).

The Respiratory system is an integrated system of organs involved in the intake and exchange of oxygen and carbon dioxide between an organism and the environment. Your Respiratory system is made up of the organs in your body that help you breathe. The Respiratory system is the system of the body that deals with breathing. The trachea is a wind pipe. The trachea is a pipe shaped by rings of cartillage. A Bronchi are two tubes that carry air into the lungs. The Respiratory system consistes of many different organs. The organs are the lungs, trachea, bronchi, alveoli, diaphragm, nose, mouth, and pharynx. In the Respiratory system the right lung is larger and has more lobes that the left lung becuase the heart is normally located on the left side, and takes up space where the lung would had been. The functions of the Respiratory system is to supply the blood with oxygen in order for the blood to deliver oxygen to all parts of the body. The Respiratory system is also used for the of exchange gases. The importance of the Respiratory system is that it allows for the exchange of gases; meaning carbon dioxide and oxygen. These gas exchanges occur in the alveoli's and the capillaries. This gas exchange of gases is the Respiratory system's means of getting oxygen to the blood. The goal of breathing is to

Both tracts work together to obtain the oxygen and remove the gas. The upper respiratory tract takes care of air conduction and the lower respiratory tract works on gaseous exchange.

Passages that filter incoming air and transport it through the body, into the lungs and to many microscopic air sacs where gases are exchanges is called the respiratory system. Respiration is the process of exchanging gases between the atmospheres and the body’s cells. There are several events that happen in the respiratory system they

Small air sacks called alveoli are at the tips of the bronchioles. When air reaches them, the oxygen concentration is high, which causes diffusion into red blood cells travelling through pulmonary capillaries (7). The red blood cells then distribute the new oxygen to the rest of the body. When they reach the alveoli again, they exchange carbon dioxide (a form of cell waste) for new oxygen, and repeat the process. The carbon dioxide is moved through the bronchioles, bronchi, and trachea in the form of exhalation.

The main organs of the respiratory system are the lungs – they are the location where the gas exchange between oxygen and carbon dioxide takes place. The lungs therefore expand when you breathe in, and retract when you breathe out. This is done through the diaphragm – a sheet of muscle that is positioned under the lungs. As one inhales, their diaphragm contracts and moves itself downward, increasing the space for your lungs to expand to. The ribs also move to enlarge the possible area the lungs can expand to. This pressure causes air to be sucked through the body to the lungs. When one exhales, the opposite takes place – the diaphragm moves upwards and returns to normal, allowing the process to happen again.

The respiratory system is the process responsible for the transportation and exchange of gases into and out of the human body. As we breath in, oxygen in the air containing oxygen is drawn into the lungs through a series of air pipes known as the airway and into the lungs. As air is drawn into the lungs and waste gas excreted, it passes through the airway, first through the mouth or nose and through the pharynx, larynx and windpipe – also known as the trachea. At this point it then enters the lungs through the bronchi before finally reaching the air sacs known as alveoli. Within the lungs, through a process known as diffusion, the oxygen is transferred to the blood stream through the alveoli (air ducts) where it is then transported inside

e purpose of the respiratory system is to bring the air we breathe into close contact with the blood in order for the absorption of oxygen and expulsion of carbon dioxide. The respiratory system consists of a pair lungs which are connected to the mouth via the trachea and bronchi. The ribs and intercostal muscles are part of the respiratory system. This is because they not only protect the lungs, trachea and bronchi but also move and assist with breathing.

The air enters in your nose and mouth and goes through your throat and the pharynx and the larynx. Then it goes to the trachea where it separates into two tubes that are the bronchi. The bronchi

Normal respiration consists of inhalation and exhalation. Inhalation is taking in oxygen and delivering it to all cells in the body and exhalation is picking up carbon dioxide waster product of cells and taking it out. Air travel from the nose or mouth into the larynx into the trachea and ends up in the lungs where oxygen is dropped and carbon dioxide is picked up. Oxygen is really important for cell function and when oxygen is not delivered, cells begin to die. So when process of breathing does not work properly other methods of delivering oxygen are used such as tracheostomy.
