The Respiratory System Essay

Humans and the Rat Respiratory System The human respiratory system is very similar, if not practically identical, to the respiratory system of a rat. The only notable difference is the division of the lobes in human lungs. The left lung of a rat is composed of 1 lobe, while the right lung has 4 lobes. The right lung of a human contains 3 lobes and the left lung is composed of 2 lobes. Other than that (and some structural differences along with size) the human and rat respiratory systems work in the same…

RESPIRATORY SYSTEM The respiratory system consists of all the organs involved in breathing. These include the nose, pharynx, larynx, trachea, bronchi and lungs. The respiratory system does two very important things: it brings oxygen into our bodies, which we need for our cells to live and function properly; and it helps us get rid of carbon dioxide, which is a waste product of cellular function. The nose, pharynx, larynx, trachea and bronchi all work like a system of pipes through which…

1. How does the Respitory system work? The main Function of the respitory system is gaseous exchange. This refers to the process of oxygen and carbon dioxide moving between the lungs and blood. Gaseous exchange in the lungs refers to the movement of oxygen into the body, and the removal of carbon dioxide from the body. It takes place in the lungs, especially in the alveoli surface through diffusion. During inspiration, the diaphragm and the surrounding muscles contract. The diaphragm moves down…

So when we breathe air in, if we didn't humidify a little bit, it would potentially dry out our nasal passages. So as soon as we breathe the air in, the nasal cavity will moisten it up, filter it, and then send it down to the deeper parts of the respiratory tract. So again, those meatuses act as sped bumps. They're going to kick up turbulence in the air to sallow us to filter and humidify better. And we know that the air we take in is humidified because if breathed into your hand. And next we…

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…

A&P II Instructor: David Armoogam September 10, 2010 The respiratory system helps with breathing, inhaling and exhaling. The respiratory systems main function is to give oxygen to the body’s cells and get rid of the carbon dioxide the cells produce. Breathing would be impossible without the respiratory system, which includes the nose, throat, voice box, windpipe, and lungs. In this essay I plan on explaining how the respiratory system functions as well as its parts. The exchange of two gases called…

Respiratory System The respiratory system consists of a series of tubes that air passes on its journey from the nostrils. The nostrils open into the nasal cavities, which are lined with moist eiliateol epithelium. Whether one breathes through the nose or the mouth, a breath of air enters the body and flows through the nasal cavity to the pharynx (throat). The back of the nasal cavities is continuous with the throat region, or pharying. Air flows through the larynx (voice box) and into the…

Emphysema The human respiratory system includes the lungs, pathways connecting them to the outside environment and structures in the chest that help the movement of air in and out of the lungs. When the movement of air in and out of the lungs is limited, people experience a difficulty in breathing. Emphysema is a type of chronic lung-disease. It results when the air sacs walls are heavily damaged causing loss of elasticity. The main cause of emphysema is smoking and the treatments can’t reverse…

foods. The respiratory system is the collection of tissues and organs in your body that empower you to breathe. This system incorporates your airways routes, your lungs and the veins and muscles joined to them that cooperate so you can relax. The respiratory system essential role is to supply oxygen to all the parts of your body. It performs this through breathing: breathing in oxygen-rich air and breathing out air loaded with carbon dioxide, which is a waste gas. The respiratory system is made up…

how our body inhales oxygen and exhales carbon dioxide. This is possible because of the respiratory system. This system in the body is what allows us to breathe and continue our lives. An average human breathes fifty million times in their lifetime! The structure affects the function of this intricate and wonderful system that keep us alive. It all starts from the nose. The basic parts of the respiratory system are the lungs, nose, trachea, diaphragm and alveoli. When we inhale, the diaphragm, which…
