The pathway of air in the respiratory system starts with the external organs of the nose and mouth. Nose: Air is inhaled through the nostrils and sometimes through the mouth where it is filtered by the hairs and cilia to remove dust particles and moistened. The nasal cavity also moderates the temperature of the inhaled air. Pharynx: This is a common passage for food, water, and air. It leads from both the nose and the mouth and leads to both the trachea windpipe and the oesophagus foodpipe. Larynx: This is the voice box situated just over the trachea and has a flap called the epiglottis which closes during swallowing to prevent food from entering the trachea and opens during breathing.

Trachea: Air now enters the windpipe which is situated behind the sternum breastbone and between the two lungs. Bronchus: From the trachea, two bronchi one bronchus for each lung enter the lungs and divide and subdivide into secondary and tertiary bronchi, getting narrower as they proceed into the lung. Bronchioles: The tertiary bronchi branch into fine tubules called bronchioles, the last passageways for air. Air ends its pathway in the alveoli sing. These alveoli are surrounded by capillaries that connect the pulmonary arteries and veins and that enable transfer of oxygen and carbon dioxide.

The complex yet flexible cellular response to pathogens is orchestrated by the interaction of multiple signalling and metabolic pathways. The molecular regulation of this response has been studied in great detail but comprehensive and unambiguous diagrams describing these events are generally unavailable.

However, these pathways are commonly viewed as separate entities rather than an integrated network of molecular interactions. Here we describe the construction of a logically represented pathway diagram which attempts to integrate these four pathways central to innate immunity using a modified version of the Edinburgh Pathway Notation.

The pathway map is available in a number of electronic formats and editing is supported by yEd graph editor software. The map presents a powerful visual aid for interpreting the available pathway interaction knowledge and underscores the valuable contribution well constructed pathway diagrams make to communicating large amounts of molecular interaction data. Furthermore, we discuss issues with the limitations and scalability of pathways presented in this fashion, explore options for automated layout of large pathway networks and demonstrate how such maps can aid the interpretation of functional studies.

The innate immune response is executed at the molecular level by a complex series of interwoven signalling pathways.

In this context, pathways may be defined as a network of directional interactions between the components of a cell which orchestrate an appropriate shift in cellular activity in response to a specific biological input or event.

Whilst our ability to perform quantitative and qualitative measurements on the cellular components has increased massively in recent years, as has our knowledge on how they interact with each other, we still struggle to translate these observations into graphical and computationally tractable models.

However without such models we can not hope to truly understand biology at a systems level. Traditionally, representations of molecular pathways have been produced ad hoc and frequently included in reviews and original papers. Whilst they are clearly useful aids to understanding cellular events, even at their best, they are not sufficient by themselves, relying on extensive textual descriptions to explain what is shown pictorially.

Recent years have seen considerable growth in the availability of public and commercial databases offering searchable access to pathways and interaction data derived from a combination of manual and automated text mining extraction of primary literature, reviews and large-scale molecular interaction studies.

Using these tools it is possible to view a range of canonical pathway views or generate networks of interactions based on a given query. However, all of these efforts are let down by one or a number of key factors.

The notation used in diagrams to depict one molecule's interaction with another is varied, often ambiguous and therefore limited in its ability to depict the exact nature of the relationship between components of a pathway. There is often a lack of direct access to the experimental evidence relating to the interactions depicted or to the dataset as a whole. Similarly, labelling of the pathway components often uses non-standard nomenclature or mixes protein names from one species with that of another, such that again the reader is left uncertain as to what exactly is being shown.

Finally, pathway diagrams usually focus only on a small part of a biological system and one which often reflects the curator's bias, such that the 'same' pathway described by different individuals may share little in common.

Whatever the source of these pathways and networks they generally suffer from graphically poor representation with ambiguity around the precise identity of what is being shown and the exact nature of their interaction. In order to address these issues the groups of Kohn and Kitano began to devise new approaches to pathway notation using many ideas adopted from the electronics industry [ 1 — 3 ]. In particular the MIM molecular interaction map notation [ 3 ] a form of entity-relationship representation and the process description notation PDN [ 1 ], respectively.This page will focus on airway anatomy and function for emergency medical technicians EMT.

Airway anatomy can be divided into the upper airway and the lower airway. First responders need to be familiar with respiratory system anatomy in order to keep patients healthy, breathing and adequately ventilated.

Below are detailed graphics of both the upper and lower respiratory tracts. The main components of upper respiratory tract anatomy are:. Air enters through the mouth and nose and travels into the oropharynx and nasopharynx. It is warmed and moistened before traveling through the glottic opening and past the larynx into the lower respiratory tract.

The main components of the lower respiratory tract anatomy are:. After passing through the upper airway, air travels down the trachea and into the left and right mainstem bronchi.

Deeper in the lungs, the mainstem bronchi divide smaller bronchi and then into bronchioles. The bronchioles terminate into the alveoli, which is where gas exchange takes place.

This is why the right bronchus is a common location of aspirated objects. The upper airway transitions into the lower airway here.

The right lung is made up of three lobes and the left lung is made up of two lobes. The right lung is separated by the oblique and horizontal fissures. The horizontal fissure divides the upper and middle lobes while the oblique fissure divides the middle and lower lobes.

In the left lung the oblique fissure separates the upper and lower lobes. This website uses cookies to improve your experience while you navigate through the website.

The gas exchange process is performed by the lungs and respiratory system. In the throat, the trachea, or windpipe, filters the air. The trachea branches into two bronchi, tubes that lead to the lungs. Once in the lungs, oxygen is moved into the bloodstream. Blood carries the oxygen through the body to where it is needed. An exchange of oxygen and carbon dioxide takes place in the alveoli, small structures within the lungs.

The carbon dioxide, a waste gas, is exhaled and the cycle begins again with the next breath. The diaphragm is a dome-shaped muscle below the lungs that controls breathing. The diaphragm flattens out and pulls forward, drawing air into the lungs for inhalation. During exhalation the diaphragm expands to force air out of the lungs. Adults normally take 12 to 20 breaths per minute. Strenuous exercise drives the breath rate up to an average of 45 breaths per minute.

Other roles of the respiratory system include the filtration of environmental air to remove harmful substances from air that is inhaled and to allow speech.

In order to fulfill this primary role, the respiratory system works in close concert to the cardiac system which consists of the heart muscle and the circulatory system which consists of the arteries, the arterioles, the capillaries, the venules, and the veins.

The circulatory and cardiac systems will be fully detailed below. The respiratory system is also in close proximity to the heart and the heart and lungs are connected to the circulatory system, as shown in the picture below. The respiratory system can be divided into the upper respiratory system, which can also be referred to as the upper airway and the upper respiratory tract, and the lower respiratory system, which can also be referred to as the lower airway and the lower respiratory tract, as shown in the picture below.

The upper respiratory tract consists of the nose and nares also referred to as the nostrils, the pharynx, and the larynx; and the upper respiratory tract consists of the trachea, the bronchi, the lungs, and the alveoli.

Air, including the oxygen in environmental air, enters the body through the nares and sometimes through the mouth when the person is a "mouth breather". The nose and the nares, with their tiny hair-like structures called cilia, filter environmental air to free it of bacteria and other harmful substances such as dust and air pollution.

As air moves through the nose, it is also warmed before it moves along to the pharynx and the other anatomical structures of the upper and lower respiratory system. The flow of air from the environment moves through the respiratory system in these sequential steps during inspiration:.

The human body has two lungs which are the right lung and the left lung. The lungs share space in the thoracic, or chest cavity, of the human body with the heart which lies between the left and right lungs, as shown in the picture above, and above the diaphragm which is the major breathing muscle of the body and at the level of the first rib of the body. Like the heart, the lungs are protected with boney structures like the ribs and the spine.

The left lung lies on the left side of the heart and the chest cavity, and the right lung lies on the right side of the heart and the chest cavity.

The right lung is larger than the left lung because of the left lung shares and occupies the left side of the chest cavity along with the largest part of the heart. The smaller left lung has two lobes and the larger right lung has three lobes. The two lobes of the left lung are the upper lobe and the lower lobe; and the three lobes of the right lung are the upper lobe, the middle lobe, and the lower lobe.

The pharynx is a part of the respiratory system and also a part of the gastrointestinal system. The pharynx receives air from the nares or the mouth and it also receives food from the mouth. When people say that their "food has gone down the wrong pipe", they are experiencing an abnormally small amount of food moving from the pharynx into the tracheal windpipe without the help of the epiglottis which, under normal situations, closes off the trachea from food and fluids.

The epiglottis is the "flap" like projection in the back of the mouth that is attached to the larynx. It goes up during breathing to allow the air to enter into the trachea and it moves down during the swallowing of food and drinking fluids to allow the food to enter the esophagus which is part of the gastrointestinal and digestive system.

This part of the respiratory and digestive system also plays a role in the gag and cough reflexes.
