The Function Of The Lungs

The respiratory tract is the system that allows you to breathe air into your lungs and back out again. The passageway that air travels through is divided into two sections, the upper respiratory tract, and the lower respiratory tract.

Spirometry is the most popular lung function test. The patient performs a maximal inhalation and then forcefully exhales as quickly and as long as they are able. The spirometer measures the volume of the air exhaled by patients. These measurements are taken at two intervals. The first measurement is the forced expiratory volume in one second (FEV1), records the volume of air exhaled after one second. The second measurement is taken at the point where the patient has fully exhaled the volume of inhaled air; this measurement is the forced vital capacity (FVC) (Harpreet Ranu et al.,

There are two main categories of diseases that can affect the lungs, which are obstructive diseases and restrictive diseases. These lung diseases can have detrimental effects on the lung because they can result in decreased airway size, swollen or loss of alveolar sacs, and ultimately reduced gas exchange. Lung diseases, as well as the overall function of the lung can be evaluated using a method known as spirometry. Spirometry is a tool used to evaluate the breathing mechanisms of a patient and allow doctors to detect pulmonary diseases in patients displaying abnormal lung function. Spirometry can consist of static and dynamic tests to measure variables such as vital capacity, which is the highest volume of air that can be exhaled out of the

Exacerbations due to chronic obstructive pulmonary disease are one of leading causes of the increasing number of emergency room visits nationally as well as in the state of Kentucky (21,22). As stated there are many reasons for the development of chronic obstructive pulmonary disease and these reasons are also the cause of many of the acute exacerbations, the main risk factor is

Lung capacity is the total amount of air that a person’s lungs can hold. Lung capacity can be increased through aerobic exercises, resulting in a larger lung capacity to provide better oxygen transport throughout the body (2). Only one-third of lung capacity is used for normal activity, but is increased and requires more oxygen when undergoing strenuous activities. Lungs are apart of the respiratory system and help assist in breathing, so when air is inhaled, the lungs push out oxygen to the blood where it is then carried to each cell. Lung capacity varies from female to male and from athlete to singer. It has been proven that males have a larger lung capacity than females, and taller people usually have a larger lung capacity

There is a certain part of the body that is final 2 how the lungs function for them to be able to deliver oxygen and remove carbon dioxide for us to live and this is the pulmonary system. To find out how staple or healthy someone's pulmonary system is doctors can perform tests. One type of test is called the static test, in this test it focuses on the mechanical function of the pulmonary system. The second test is called the dynamic test, in this test refocus on the lungs ability to allow air ventilation. In today's lab we are to focus on the dynamic alone test. We are supposed to find the relationship of the dynamic function of the lungs and it's size.

-Trachea- Connects the larynx to the bronchi of the lungs in order to let air flow from the lungs to then respire.

The author, M.D. Jean-Paul Janssens, used changes in life expectancy as a clear alternation for respiratory diseases associated with age. Additionally, the author gathered from statistical studies on how those conditions affect daily respiratory mechanics over time. Therefore, the article is aimed towards enhancing a better understanding of respiratory changes in individuals. The three significant changes associated with age were a loss of function in respiratory muscles, modification of the chest wall, and the decrease in elasticity of lungs. In the review, the difficulty of performing a pulmonary function test on older aged individuals, due to airflow limitations, led to the development of new methods. Especially the observation on an elder’s mental capability of understanding a pulmonary function test, such as spirometry. Other methods used were tests on respiratory muscles, responses to different ranges of exercise, and observations of gas

The respiratory system is divided in two different tracks, upper tract including nose, nasal cavity, sinuses, and pharynx; Lower respiratory tract includes larynx, trachea, bronchial tree, and lungs. The system served the main purpose of transporting air into the lungs, and flows from the top to bottom.

The lungs function as an important part of the respiratory system. We, humans, have two lungs. Surprisingly, the two lungs have some differences; the right lung is slightly larger than the left lung because the left lung must leave space for the heart, and the right lung has three lobes while the left only has two. The lungs house the alveoli and the capillaries, which exchange oxygen (O) from the air that we breathe in with carbon dioxide (CO2) that has been released into the bloodstream by cells in the body. The diaphragm, a muscle which is located below the lungs, is what helps the lungs contract and expand.

Lung Capacity: The lung capacity of each person will be measured at both stages using a spirometer whilst the participant is seated and the following values will be recorded; FVC, FEV , Ratio (FEV1/FVC) and Peak Flow

The primary functions of your lung are to transport oxygen from the air you breath in into your

The respiratory system is divided into two main parts, the upper respiratory and lower respiratory tract. The upper respiratory tract consists of the nasal cavity which is a hollow space behind the nose, it is lined with mucous membrane and small hairs, which traps smaller particles entering with the air, the nasal cavities main purpose is to heat, humidify and filter the air before it passes into the lungs (Whittemore and Cooley, 2009 ). The sinuses are hollow areas in the bones of the skull and are lined with a mucous membrane that open into the nasal cavity, they help to keep the skull light. The pharynx is around 12.5 cm long and joins the posterior oral and nasal cavities to the larynx and oesophagus. It is a member of both the respiratory system and the digestive system as it allows food and air to pass through it, the food and air are both directed through their own passage ways which is controlled by the epiglottis, which is a flap of elastic tissue that acts like a lid to cover the trachea in order to avoid substances from entering the larynx (Callentine, 2015). The larynx is located at the upper part of the air passage the walls of the larynx are made up of muscle and cartilage, it contains the vocal cords, sound is produced by air passing through the larynx on the way to the lungs and connects the pharynx to the trachea (Wilkins and King, 2002). All of these organs which are situated in the respiratory system are located outside of the chest cavity.

The primary functions of the respiratory system include the following. The respiratory system takes in oxygen. It does this by using a process that is called breathing. In order to breath, the diaphragm flattens, thus, allowing the lungs to expand in order to transfer oxygen into the lungs, which transfers the oxygen into the circulatory system. The respiratory system also expels carbon dioxide. In other words, it breaths it out. The diaphragm rises to push the carbon dioxide out of the lungs in order to expel it from the body.

There are three major organs in the upper respiratory tract. The nose, the pharynx, and the larynx are all located outside of the chest cavity and play a major role in sustaining life. These three anatomical parts help draw in oxygen from the atmosphere to the lungs for gas exchange. However, these organs do not only contribute to the exchange of gases but also provide separate functions as well.
