This essay will explain the physiologies of the respiratory system and the cardiovascular system and how they work in the metabolism of energy in the body.

• Pulse Oximetry - Tests the percentage of oxygen in the blood. 95% or more is a normal level,

The primary function of the respiratory system is the exchange of gases. The respiratory system allows oxygen and carbon dioxide exchange, this is necessary to sustain life. During the process of breathing air is inhaled and carbon dioxide is exhaled, this change of gases occurs in the alveoli. The inhaled oxygen passes into the alveoli and then diffuses into arterial blood. The waste rich blood from the veins releases carbon dioxide into the alveoli which is

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.

A cough reflex clears up sputum from the nasal passages and pharynx. In the trachea there are cilia that move mucus up from the lungs. The mucus causes the cough reflex.

➢ 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

Consist of the nasal passage, pharynx, esophagus, larynx, trachea, lungs, diaphragm, bronchi, and pulmonary artery and vein.

Air (oxygen) is inhaled into the body by the nose. The air is warmed filtered and moistured in the nasal cavity as the air needs to be cleaned before passing it along to the pharynx. Mucous is held in the sinus cavity. With the joint help from the mucous and the tiny hairs in the nose our nose ensures that the air is cleared of pathogens so that the air is clean to move on to the pharynx. The tiny hairs in the nose causes us to sneeze resulting in pathogens that may have been inhaled to be sneezed out and released back into the atmosphere.

passages. The nasopharynx serves as a passageway for air from the nose to the throat, and

On top of the nasal cavity, lies the olfactory epithelium (mucous tissue that covers the cribriform plate and contains the cilia necessary for olfactory receptors). The process starts when air enters the nasal cavity and makes its way to the olfactory receptors. These olfactory receptors are located in the olfactory epithelium and contain many bipolar neurons. These receptors send processes to the epithelium where it divides into 10 to 20 cilia. Molecules of odor then must dissolve in the mucus and stimulate the receptors in the cilia, which detect aromatic molecules. Next, each olfactory receptor cell sends an axon into the olfactory bulb, which is located at the end of the olfactory tract. Here, it forms synapse with dendrites of mitral cells (neurons of olfactory bulb), which takes place in the dendritic and axonal aborizations, called the olfactory glomeruli. From there, the axons travel to the rest of the brain, some terminating in the ipsilateral forebrain and contralateral olfactory bulb.

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

This concept is taken from Block 4, Module 6 which is entitled as ‘Assessment of respiratory system’. The respiratory system comprises of different organs used in respiration. Respiration involves inhalation and exchange of oxygen and carbondioxide between living organisms and the environment. The organs of respiration include; the nose, pharynx, larynx, trachea, 2 bronchi, bronchioles, 2 lungs and muscles of breathing (the intercostal muscles and the diaphragm).

Air enters your lungs through a system of pipes called the bronchi. These pipes start from the bottom of the trachea as the left and right bronchi and branch many times throughout the lungs, until they eventually form little thin-walled air sacs or bubbles, known as the alveoli. The alveoli are where the important work of gas exchange takes place between the air and your blood. Covering each alveolus is a whole network of little blood vessel called capillaries, which are very small branches of the pulmonary arteries. It is important that the air in the alveoli and the blood in the capillaries are very close together, so that oxygen and carbon dioxide can move (or diffuse) between them. So, when you breathe in, air comes down the trachea and through the bronchi into
