- The respiratory system provides oxygen to the body’s cells while removing carbon dioxide, a waste product that can be lethal if allowed to accumulate. There are 3 major parts of the respiratory system: the airway, the lungs, and the muscles of respiration.The airway, which includes the nose, mouth, pharynx, larynx, trachea, bronchi, and bronchioles, carries air between the lungs and the body’s exterior.The lungs...Click to read more below. The cells of the human body require a constant stream of oxygen to stay alive.ulmonary ventilation is the process of moving air into and out of the lungs to facilitate gas exchange. The respiratory system uses both a negative pressure system and the contraction of muscles to achieve pulmonary ventilation.

Respiratory system X-ray video of a female American alligator while breathing. Breathing is the process that moves air in and out of the lungs, to allow the diffusion of oxygen and carbon dioxide to and from the external environment into and out of the blood. Breathing sometimes also refers to the equivalent process using other respiratory organs such as gills in fish and spiracles in certain arthropods.

Bronchioles: Definition & Function The respiratory system consists of a pair of lungs and a trachea through which we draw in air. Air pressure of the atmosphere forces the air inside. For this to happen, the body must lower air pressure inside the chest cavity. It does this by expanding the cavity, using muscles in the rib cage and a special muscle called a diaphragm located under the lungs. When we breathe, the air is first drawn in through the mouth and nose. Moving downward, it goes through the pharynx (or the throat) and through the larynx (or the voice box). From there, it enters the main airway called the trachea. The trachea has rings of cartilage supporting it. The trachea branches off into two bronchi, one for each lung.

Tracheal Diseases The trachea (windpipe) is the airway that extends downward from the larynx (voice box) and branches into two airways that lead to the lungs, called the left and right bronchi. Each bronchi divides into smaller tubes in a pattern that resembles an upside-down tree, with the trachea as the tree trunk.he trachea (windpipe) is the airway that extends downward from the larynx (voice box) and branches into two airways that lead to the lungs, called the left and right bronchi.

- Oxygen passes through the larynx and trachea. The respiratory system is made up of the mouth, throat, nose, sinuses, bronchial tubes, and lungs. The respiratory system facilitates breathing and is necessary to maintain life.

Trachea (Windpipe) Click to read more below. The trachea (or windpipe) is a wide, hollow tube that connects the larynx (or voice box) to the bronchi of the lungs. It is an integral part of the body’s airway and has the vital function of providing air flow to and from the lungs for respiration.

What Is Lungs Definition? Lungs are the major organ of our respiratory system, helping us obtain oxygen and get rid of carbon dioxide. Our chest cavity houses a pair of lungs which open to the external environment through the nose and mouth. A cylindrical tube, called trachea, is the main link between the lungs and the nose and mouth. When we breathe in, air travels through the trachea to our lungs. As the trachea moves down the chest, it splits into two branches called bronchus, one for each lung. Each bronchus then further subdivides into several smaller tubes called bronchioles.

- The trachea is a cartilage tube and represents the initial part of the lower respiratory tract. It connects the pharynx and larynx to the lungs and allows normal passage of the air to and from the lungs.

airway An airway device (formerly used in EMS systems) consisting of an esophageal tube with a 37-cm long tube attached to a mask. To be effective, the device requires an airtight mask seal on the patient’s face. A balloon at the distal end of the tube is inflated following blind insertion into the esophagus.

Airway management Airway management is a primary consideration in cardiopulmonary resuscitation, anaesthesia, emergency medicine, intensive care medicine and first aid. Airway management is covered under A In the ABC treatment mnemonic.n advanced airway management foreign objects are either removed by suction or with e.g. a Magill forceps under inspection of the airway with a laryngoscope or bronchoscope. If removal is not possible surgical methods should be considered.

Respiratory System The pharynx, also known as the throat, is a muscular funnel that extends from the posterior end of the nasal cavity to the superior end of the esophagus and larynx. The pharynx is divided into 3 regions: the nasopharynx, oropharynx, and laryngopharynx.here are 3 major parts of the respiratory system: the airway, the lungs, and the muscles of respiration. The airway, which includes the nose, mouth, pharynx, larynx, trachea, bronchi, and bronchioles, carries air between the lungs and the body’s exterior.

Trachea The trachea, colloquially called the windpipe, is a cartilaginous tube that connects the pharynx and larynx to the lungs, allowing the passage of air, and so is present in almost all air-breathing animals with lungs. The trachea extends from the larynx and branches into the two primary bronchi. At the top of the trachea the cricoid cartilage attaches it to the larynx. This is the only complete ring, the others being incomplete rings of reinforcing cartilage.
