The Respiratory System Essay

Task 4 I will be taking about the digestive system, cardiovascular system and the respiratory system. DIGESTIVE SYSTEM The digestive system is very important in digesting food and breaking it down so it can be digested easily. The digestive system turns food into energy. Throughout the process there are nutrients which are absorbed. There are many things that contributed to the digestive system such as the mouth which produces saliva which helps to break down food and nutrients such as carbohydrates…

and each system within the body follows common principles for this exchange, but adapts to suit its own requirements and function. The human body has a smaller surface area to volume ratio in comparison to smaller organisms, which are able to gain all gases that are needed though simple diffusion, and therefore is not able to complete all of the exchanges of the materials it requires in the same way. To ensure that it obtains all of the materials that are needed, specialised systems are present…

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…

Respiratory Distress Consisting of respiratory circulation, upper and lower airways, and the chest wall the pulmonary system interchanges oxygen and carbon dioxide between our blood and the environment we live in. The pulmonary system works by moving air into and out of the lungs by ventilation, then diffuses the gases between pleural spaces in the lungs and bloodstream. The act of ventilation is involuntary, being controlled by the sympathetic and parasympathetic nervous system of the autonomic…

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…

1: The respiratory system and the effect of exercise Every living organism is composed of cells. Cells consume Oxygen (O2) and produce Carbone dioxide (CO2). The respiratory system has for main function to provide the Oxygen (O2) and dispose of the Carbon dioxide (CO2) produce by the cells through the process of respiration. During exercise the demand of Oxygen (O2) and the production of Carbon dioxide (CO2) raises which affect the respiratory system. This essay will discuss the respiratory system…

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…

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…
